Conventions used in this guide Typefaces

We use different typefaces for different items in this guide. In most cases the meaning is obvious from the context. If you are not sure what a certain typeface represents, you can check it here.

Convention

Usage

Bold

Bold indicates the names of keyboard keys. Bold is also used for general emphasis in text.

Arial bold

Any text that you see in the user interface appears in Arial bold. Items such as window and dialog box titles, field and button names, combo box options, and list box items are displayed in this typeface.

Italic bold

New terms are in italic bold when they appear in the current context for the first time.

Monospace

Extracts of Tekla Structures’s program code, HTML, or other material that you would normally edit in a text editor, appears in monospaced font. Filenames and folder paths appear in monospace. Also all the text you enter yourself appears in monospaced font.

Noteboxes

12

We use several types of noteboxes, marked by different icons. Their functions are shown below:

A tip might introduce a shortcut, or suggest alternative ways of doing things. A tip never contains information that is absolutely necessary.

A note draws attention to details that you might easily overlook. It can also point you to other information in this guide that you might find useful.

You should always read very important notes and warnings, like this one. They will help you avoid making serious mistakes, or wasting your time.

This symbol indicates advanced or highly technical information that is usually of interest only to advanced or technically-oriented readers. You are never required to understand this kind of information.

1.1 General information Tekla Structures is a tool for structural engineers, detailers, and fabricators. It is an integrated model-based 3D solution for managing multi-material databases (steel, concrete, timber, etc.). Tekla Structures features interactive modeling, structural analysis and design, and automatic drawing creation. 3D model

www.cadfamily.com

Using Tekla Structures, you can create a real-life model of any structure, including information necessary for manufacture and construction. The 3D product model includes the structure’s geometry and dimensions, and all the information about profiles and cross sections, connection types, materials, structural analysis, etc.

Up-to-date drawings

You can automatically produce drawings and reports from the 3D model, at any time. Drawings and reports react to modifications in the model, and are always up to date. Tekla Structures includes a wide range of standard drawing and report templates. You can also create your own templates using the Template Editor.

Sharing models

Tekla Structures supports multiple users working on the same project. You and your partners can work together on the same model, at the same time, even in different locations. This increases accuracy and quality, because you always use the most up-to-date information.

Main features

Tekla Structures includes:

Easy to use

• •

Useful modeling tools, such as 3D grids, adjustable work area, and clash checking.

•

Modeling tools to create complex structures, such as staircases and trusses.

•

Intelligent connections, such as end plates and clip angles, to automatically connect main members.

•

A custom component editor that you can use to create your own parametric connections, details, and parts.

•

Links to transfer data between Tekla Structures and other software, such as AutoCAD, STAAD, and MicroStation.

•

Drawing wizards to create several drawings with one click.

•

Data output for CNC machines.

Catalogs of available material grades, profiles, and bolts.

If you need assistance when working with Tekla Structures, use the F1 key to quickly access the context-sensitive online help. The online help is a comprehensive source of information, with full-text search and easy navigation.

Single-user mode vs multi-user mode Tekla Structures can be used in either single-user or multi-user mode. During the installation you are asked whether you want to install the multi-user facility. Single-user mode

When one user at a time is to work with a model, Tekla Structures should be run in single-user mode. In single-user mode, only one user can work with each model at any time.

Multi-user mode

If several users will work with a model simultaneously, you can choose to run Tekla Structures in multi-user mode. We recommend that you only run Tekla Structures in multi-user mode if the users will make use of the additional features of multi-user mode. To run Tekla Structures in multi-user mode, one machine in the network has to be set up as a server running the Tekla Structures server program. For more information, see Multi-user mode in the online help.

Tekla Structures editors Tekla Structures includes the following editors: Model, Drawing, Symbol, Template, Custom Component. Model

The Model Editor is the main and starting mode of Tekla Structures. You create and analyze models, and initiate drawing and report creation using the Model Editor.

Drawing

In the Drawing Editor, you work with drawings. Tekla Structures opens the Drawing Editor when you open any drawing.

Symbol

In the Symbol Editor (SymEd), you can create and modify symbols for use in drawings, reports, and templates. To open the Symbol Editor, click Tools > Symbols... in the Model or Drawing Editor.

Template

Use the Template Editor (TplEd) to create and modify templates used in drawings and reports. To open the Template Editor, click Tools > Templates... in the Model or Drawing Editor.

18





Custom Component

In the Custom Component Editor, you can create your own connections, details, and parts, and define their properties. You can build in dependencies between objects to make custom components parametric and have them adapt to changes in the model. To open the Custom Component Editor, select a component and click Detailing > Edit custom component.

1.2 Screen layout When you start Tekla Structures, a new window appears on the screen. The following illustration identifies the various areas of the Tekla Structures Model Editor window:

Status bar displays the prompt and the status of some settings Snap settings control which points you can snap to and pick Select switches determine selectable objects Pull-down menus contain all commands Steel beams, columns, plates Concrete footings, beams, columns Commands for creating views Toolbars can either be docked or floating Initially, most of the menu options and all the icons are gray indicating that they are inactive. When you open or create a model, the icons and available menu options will become active.

Screen components This section briefly describes several important screen components. Menu bar

The menu bar located under the blue title bar has pull-down menus containing all the Tekla Structures commands. To select a command, click a menu title and then select the command.

Toolbars

The toolbars are located under the menu bar. They contain icons which give easy access to the most frequently-used commands. To execute a command, click the appropriate icon. Use the icon as an alternative to selecting commands from a pull-down menu. For more information, see Toolbars (p. 23).

Tooltips

When you move the mouse pointer over an icon, a tooltip displays the name of the icon:

If the enhanced tooltips are switched on, the tooltips are not displayed. The enhanced tooltips are switched on by default.

Enhanced tooltips

20

The enhanced tooltips give more information about the command and how it can be executed. They also give examples, hints and tips:





On the basis of the information in the enhanced tooltip you are able to decide whether the command is the one that you need for your current task. You can also open the related online help topic by clicking the More... button. To hide or display the enhanced tooltips, click Tools > Options > Enhanced Tooltips. Menu tooltips

The menu tooltips provide the same functionality as the enhanced tooltips, but for menu commands. The menu tooltips are displayed in a separate window, which you can drag and drop to any position on the screen:

To hide or display the menu tooltips, click Tools > Options > Menu Tooltips. Dialog boxes

Tekla Structures displays a dialog box if you select a command whose name has three dots after it, e.g. Select.... You can also double-click an object or icon. For more information, see Inputting information (p. 28).

To display the current properties of an object type, double-click the corresponding icon. Tekla Structures displays a properties dialog box, and you can change the properties before applying the command. To display the properties dialog box of an individual object, double-click the object. Switches

Select switches and Snap settings are special toolbars containing switches which control the selection of objects, and snapping to points.

Use select switches to define which object types can be selected. With them you can limit selection. For example, if only the Select welds switch is active, Tekla Structures only selects welds, even if you select the entire model area. For more information, see Selecting model objects (p. 36).

www.cadfamily.com




21

The two circled pairs of switches control whether you can select:

• •

Components or objects created by components, or Assemblies or objects in assemblies.

You need to activate snap switches to pick different positions and points, e.g. line ends and intersections. For more information, see Specifying points (p. 33).

The two circled switches define whether you can pick reference points or any other points on objects, e.g. part corners. Either or both of these switches must be active for the other switches to work. Status bar

Tekla Structures displays prompts and messages on the status bar located at the bottom of the Tekla Structures window. The status bar also displays the following information:

• •

The status of Xsnap (T), SmartSelect (S), and Drag and drop (D)

•

The middle mouse button mode (Pan or Scroll)

•

The current phase

•

The number of selected objects and handles

The level in assembly or component hierarchy (0–9)

For more information, see Settings (p. 161). Warning messages

Tekla Structures displays warning messages when necessary, for example when you are about to copy or move objects outside the work area. To prevent Tekla Structures from displaying the warning messages again, select the Do not show this message again checkbox.

To re-display the warning messages, press Shift when the warning message should appear, for example when you are copying or moving objects outside the work area, and Tekla Structures displays the warning message again.

Using windows A typical Windows workspace can contain many windows. You can stack windows on the workspace, just like sheets of paper on a desk. Windows may partially or completely hide other windows. Only one window is active at a time, but Tekla Structures may also produce information in the inactive windows.

22





Use the commands on the Window menu and View menu to control the windows.

Buttons Fields

Components in dialog boxes Dialog boxes may have following components for described purposes:

Component

Field

Is used to Display, enter, and modify information. To select the field, point to it and click. An Ishaped blinking cursor appears at the beginning of the field and marks your typing position. Group related settings that allow only one selection at a time. To select an option, click the appropriate button.

Radio buttons Group settings that can be set in any combination, and are usually displayed as small square buttons.

Checkboxes

List box

Present a collection of options in a list. To select an option, point to the list you want to display, click, drag the pointer to highlight the desired option, and then single-click. Run a command immediately.

Button Select options from a list. A list can have both horizontal and vertical scrollbars for scrolling the visible portion of the list items. When you select a list item, it is highlighted. There are two ways to select an item on the list:

Multiple selection list

30

•

Point to the item you want to select and click.

•

Use the Down and Up arrow keys to move the highlight to the item you want to select, and press Enter.





Tabs Information in some Tekla Structures dialog boxes has been divided up on several tabs. This makes the dialog boxes easier to use. Moving from tab to tab does not affect the information they contain. The common buttons located at the top and bottom of a dialog box affect all the tabs in the dialog box. For example, when you click Save before closing the dialog box, Tekla Structures saves all information on all tabs. See also Common buttons (p. 31) and Save, Load, Save as, Help (p. 31).

Press Ctrl+Tab to switch between tabs.

Common buttons Most of the Tekla Structures dialog boxes contain common buttons. These buttons mean the same thing in all dialog boxes. The common buttons are:

Button

Description Retains the properties in the dialog box and closes the dialog box. Tekla Structures uses these properties the next time you create an object of this type. Retains the properties in the dialog box without closing the dialog box. Tekla Structures uses these properties the next time you create an object of this type. Closes the dialog box without retaining the properties in the dialog box or modifying objects. Modifies the selected object(s) using the properties in the dialog box, but does not retain the properties in the dialog box. See also Modify filter checkboxes (p. 32). Fills the dialog box with the properties of the selected object. When you select several objects, Tekla Structures takes the properties at random from one of the selected objects. Creates a new object using the properties in the dialog box. Toggles all the modify filter checkboxes in the dialog box on and off. See also Modify filter checkboxes (p. 32).

Save, Load, Save as, Help Many Tekla Structures dialog boxes have the Save, Load, Save as, and Help... buttons. You can use these buttons to save the information from the dialog box to a file, and reload it later from the file.

www.cadfamily.com




31

Button

Description

Save as

Stores the dialog box properties with the name given in the field. The Save as button also updates the Load list box. This is important if you add or delete files manually. Tekla Structures stores the properties files in the model folder. The files also include the properties in subdialog boxes. The file extensions are different for different dialog boxes. See Appendix D, File extensions, in the online help.

Load

Loads all previously stored properties to the dialog box. Tekla Structures also loads the properties of subdialog boxes, even if they are not open. You can select the name of the file you want to use from the list box.

Save

Stores the modifications of properties. Tekla Structures saves the properties in the file shown in the list box.

Help...

Displays the help topics for the dialog box.

Modify filter checkboxes The checkboxes located in front of the dialog box fields are modify filter checkboxes. They indicate the properties Tekla Structures modifies when you click the Modify button. When a checkbox is selected, Tekla Structures changes only the corresponding value.

This means you can modify a single property common to several objects. For example, to change the material of all parts in the model:

• •

Select all the parts.

•

Check only the Material field.

•

Click Modify.

Open a part properties dialog box, e.g. Beam properties.

Special keys You can use the keyboard to enter and modify text in dialog boxes, and to move the pointer in dialog boxes.

Tab

Moves the pointer to the next field or button in the dialog box. You can also scroll through lists using Tab.

Del, Backspace

Delete characters.

See also Appendix E, Reserved shortcuts, in the online help.

1.5 Specifying points Most Tekla Structures commands ask you to pick points to position objects in a model. Snap priority, snap switches, and snap settings all affect picking. Snap zone

Each object has a snap zone. It defines how close you need to pick to hit a position. When you pick within the snap zone of an object, Tekla Structures automatically snaps to the closest pickable point on that object.

You can set the snap zone using the variable XS_PIXEL_TOLERANCE. Enter the snap zone dimension in pixels.

Snap priority

If you pick and hit several positions simultaneously, Tekla Structures snaps to the position with the highest snap priority. To control which positions you can pick, use snap switches. They also define the snap priority of positions. See Snap switches (p. 33).

Snap switches Snap switches specify exact locations on objects, for example, end points, midpoints, and intersections. Snap switches help you to pick points to position objects precisely without having to know the coordinates or create additional lines or points. You can use snap switches any time Tekla Structures prompts you to specify a point, for example, if you are creating a beam. Main snap switches

www.cadfamily.com

The two main snap switches illustrated in the following table define whether you can pick reference points or any other points on objects, e.g. part corners. These switches have the highest priority. If both these switches are off, you cannot pick any positions, even if all the other switches are on.

Nearest point

Snaps to the nearest points on objects, e.g. any point on part edges or lines.

Free

Snaps to any position.





Symbol

If there is more than one point available to snap to, use the Tab key to cycle forward through the snap points, and Shift+Tab to cycle backwards through them. Click the left mouse button to select the appropriate point.

Overriding snap switches

To temporarily override current snap switch settings, do one of the following:

• •

Right-click and select the appropriate snap option from the pop-up menu. Click an icon on the Snap override toolbar.

This will only override the snap settings for the next point you pick. You can also key in position coordinates to snap to using the Enter a numeric location toolbar. For more information, see Snapping (p. 177).

Numeric snap locations

Snap settings The first list box on the Snapping toolbar defines the depth of each position you pick. The following options are available:

•

3D

Tekla Structures picks positions in 3D space.

•

View plane

Tekla Structures projects picked positions onto the view plane.

•

Auto

In perspective views, this option works like the 3D option. In non-perspective views, it works like the View plane option.

Snap switch settings Click Tools > Options > Options... > Mouse settings. Use the Mouse settings dialog box to:

•

Set Tekla Structures to display snap symbols and tooltips for the available snap points when you move the mouse pointer over objects.

•

Define a snap grid and switch it on.

Xsnap To make it easier to snap to points and position, you can use Xsnap and have Tekla Structures display visual cues when you pick. Click Tools > Options > Xsnap, or use the shortcut T. The cursor turns into a magenta crosshair. As you move the cursor over objects, you can see it snap to positions.

35

Binding objects to planes When you create distances to bind model objects together, use the second list box on the Snapping toolbar to select the plane to bind the object to. The options are boundary, center, outline, and cut planes of parts, and grid planes. Grid planes are available only in the Model Editor.

Grid plane For more information on other plane types, see Plane types in the online help.

1.6 Selecting model objects To use Tekla Structures effectively, you need to know how to select objects and use select switches. Selection filter settings also affect which objects you can select. See Selection filter (p. 153).

How to select objects You need to select objects to carry out many Tekla Structures commands. You can select objects as a sequence of single selections and/or area selections. Tekla Structures highlights the selected objects. You can use the following techniques to modify the current selection:

36





Technique

Description

Single objects

When you select objects using the mouse button, without pressing any other keys, every pick or drag selects objects. All previously selected objects are deselected.

Enclosing window selection

Drag the mouse from left to right to select all objects totally within that rectangular area.

Crossing window selection

Drag the mouse from right to left to select all objects totally or partly within that rectangular area.

Right-click

To select an object and open its pop-up menu, click the object with the right mouse button. This feature is active if you have a check mark next to Select on Right-Click in Tools > Options.

Nested components

To examine and work with nested components, hold down the Shift key and scroll with the mouse wheel. See also Main select switches (p. 38).

Nested assemblies

To examine and work on different assembly levels, hold down the Shift key and scroll with the mouse wheel. An orange box indicates the assembly which you can select.

See also Main select switches (p. 38). Assembly or cast unit

Press the Alt key while clicking a part to select the entire cast unit or assembly containing that part.




37

Technique

Description

Handles

When you want to select only the handles of a part, select the part, press the Alt key and select the part again with enclosing window selection.

See also Handles (p. 82). Adding

Press the Shift key and select objects, to add to the current selection.

Modifying

To toggle the current selection on and off, press the Ctrl key during selection. Tekla Structures deselects the objects, which are already selected and selects those, which are not previously selected.

Controlling the selection Main select switches

The main select switches shown in the following table set whether you can select objects in component or assembly hierarchy. These switches have the highest priority.

Icon

Selectable objects

Description

Components

When you click any object belonging to a component, Tekla Structures selects the component symbol and highlights (does not select) all component objects.

Component objects

Objects created automatically by a component can be selected.

Assemblies and cast units

When you click any object in an assembly or a cast unit, Tekla Structures selects the assembly or cast unit and highlights all objects in the same assembly or cast unit.

Objects in assemblies and cast units

You can select single objects in assemblies and cast units.

You can use the Select components

models, and the Select objects in components switch to select reference model objects. For more information, see Selecting reference models and reference model objects.

38





Shift + scroll

To define the level on which to select objects in nested components or assemblies, hold down the Shift key and scroll with the mouse wheel. See also How to select objects (p. 36). The active select switch defines on which level you start and toward which direction you move in the component or assembly hierarchy. The status bar shows the steps you take in the hierarchy. See Status bar (p. 22).

Example

If the Select assemblies switch is active, you can select objects in assembly hierarchy, starting from the assemblies on the highest level, move to their sub-assemblies, and finally select single parts, bolts, and so on.

is active, you start selecting from single If the Select objects in assemblies switch objects and move to bigger and bigger nested assemblies. Other select switches

For more information, see Selection filter (p. 153).

40





Canceling object selection You can cancel the object selection process if the selection takes over a defined period of time. For example, if you are working on a large model and you accidentally select all or part of the model, you can cancel the selection if it takes over 5000 milliseconds to complete. 1. 2.

Usage

Click Tools > Options > Advanced Options > Modeling Properties. Set the cancellation value for the variable XS_OBJECT_SELECTION_CONFIRMATION. The default value is 5000 milliseconds.

1.7 Using commands As you become familiar with Tekla Structures, you will find that there are several ways to do some operations. This section introduces most of the ways. Later in this manual, we refer to this section or present only the way(s) most useful for a first-time user. After some practice, you may choose a different way.

Executing commands There are several ways to execute commands in Tekla Structures. You can use icons:

Icon

• • Pull-down menu

Double-click an icon to display the properties of the object type, and to execute the command.

You can execute commands using pull-down menus. Tekla Structures contains two types of menus for basic objects:

• • Pop-up menu

Single-click an icon just to execute the command.

The commands on the Properties menu set the properties of different object types. The commands on the Points, Parts, and Create menus, for example, create objects using the properties of each object type.

A pop-up menu appears when you click the right mouse button. If you have an object selected, the commands on the pop-up menu relate to that object.

Repeating commands To repeat the last command, do one of the following:

• •

Click Edit > Repeat Last Command. Press Enter.

Creating objects Most of the commands you run in Tekla Structures create objects. To create an object, or multiple objects:

• •

Open the object type’s properties dialog box and set the object properties. Place the object(s) in the model.

You can carry out these steps in any order. For example

www.cadfamily.com

To create objects:




41

1. 2.

Double-click the icon of the object type you want to create. Tekla Structures displays the properties dialog box. Enter or modify the object properties.

3.

Click Apply or OK. See also Common buttons (p. 31).

4.

Pick points to place the object(s).

To position objects without defining their properties: 1. 2.

Single-click an icon, or a menu command. Pick points to place the object(s). Tekla Structures creates the object using the current properties of the object type. See also Modifying objects (p. 42).

To create several objects with the same properties, pick multiple points. The object commands in Tekla Structures run until you end them or use another command. See also Ending commands (p. 42).

Modifying objects To modify the properties of an object, or multiple objects:

• •

Select the object(s) to modify. Open the properties dialog box and modify the object properties.

You can carry out these steps in any order. For example

See also

To modify objects: 1. 2.

Double-click one of the objects you want to modify to open the object properties dialog box. Modify the properties. See also Modify filter checkboxes (p. 32).

3.

Select the remaining object(s) to modify. See also How to select objects (p. 36).

4.

Click Modify.

Getting Started

When you start a new Tekla Structures model, the first objects you create are grids, views, and points.

Introduction

This chapter explains the basic skills you need to create a new model, grids, views, and points in Tekla Structures. We will begin with the basic concepts, followed by general descriptions of the grid, view, and point properties. Finally we will show you how to create and manage these modeling aids in practice. Assumed background

If you are new to Tekla Structures, we recommend that you first read Chapter 1, Introduction (p. 15), to gain a basic understanding of Tekla Structures.

Points are red outside the view plane Grid is on the view plane Green dashed lines outline the work area Points are yellow on the view plane Arrow symbol indicates the work plane The coordinates symbol indicates the direction of the model View

To see your Tekla Structures model from virtually any angle, you can move and rotate the model. See Examining the model (p. 125). You can also create views. A view is a representation of a model from a specific location. Each view is displayed in its own window inside the Tekla Structures window.

Coordinate system

The symbol with three axes (x, y, and z) represents the local coordinate system and indicates the direction of the model. It is located in the lower right corner of the model view. The coordinate symbol follows the work plane.

The green cube in a wire frame view (see View type (p. 57)) represents the global coordinate system and lies at the global point of origin.

44


Getting Started www.cadfamily.com



Work plane

The red coordinate arrow symbol indicates the work plane, which is the current local coordinate system of the model. The arrow symbol shows the xy plane. The z direction follows the righthand rule. You can reset the work plane so as to ease modeling and placing objects. Most of the commands, which are dependent on the coordinate system, use work plane coordinates; e.g. creating points, part positioning, and copying always comply with the work plane coordinate system. The work plane is the same in all views.

Work area

Tekla Structures indicates the work area of a view using green, dashed lines. Defining the work area makes it faster and easier to work with the model. Objects outside the work area still exist, but they are not visible. So you can confine to a substructure, for example, and the views to the model are simpler and quickly updated.

Grid and view plane

Dash-and-dot lines show the projections of the grids which are visible on the view plane. The appearance of points also shows which view plane you are using. Points located in the view plane are yellow. Points outside the view plane are red.

Opening a model To open a Tekla Structures model: 1.

. Click File > Open... or You can only have one model open at a time. If you already have a model open, Tekla Structures prompts you to save that model.

2.

In the Open dialog box, select the model. By default, Tekla Structures searches for models in the folder you specified when you installed Tekla Structures. If your model is in another folder, click Browse... to browse for the model folder, or use the Look in list box with the recently used folders.

3.

www.cadfamily.com

Click OK to open the model.




45

If no views are visible after you have opened a model, Tekla Structures prompts you to select one. For more information, see Opening, closing, and deleting named views (p. 60).

You can also double-click a model on the list to open it, or use the Model name list box to open a recently used model.

You can sort models by clicking the column titles. When the models are sorted alphabetically by their names, you can use the keyboard to select models. For example, when you type N, Tekla Structures selects the first model starting with an N. The Open dialog box provides you with the following information:

• •

Whether the model was last saved in single-user

•

Designer

•

Description

•

Template that was used as a basis when creating this model

•

Environment

or multi-user

mode (Model type)

The version of Tekla Structures the model was created or last saved in

The Designer and Description columns show information from the Project properties dialog box. See Project setup (p. 47).

Switching between single-user and multi-user modes You can easily switch between single-user and multi-user modes by using the different options in the Open dialog box. To open a multi-user model in single-user mode: 1. 2.

In the Open dialog box, select the multi-user model. Right-click and select Open as single-user model from the pop-up menu.

To open a single-user model in multi-user mode:

Changing the server

1. 2.

In the Open dialog box, select the single-user model. Right-click and select Open as multi-user model from the pop-up menu.

3.

Tekla Structures asks for the name of the server. In the Open as multi-user model dialog box, enter the server name or select it from the list box, and then click OK.

To change the Tekla Structures server of a multi-user model: 1. 2.

In the Open dialog box, select the multi-user model. Right-click and select Change server from the pop-up menu.

3.

Tekla Structures asks for the name of the new server. In the Change server dialog box, enter the server name or select it from the list box, and then click OK.

If you change the server of a model, but the connection to the new server cannot be established, the old connection is restored.

46





The file .This_is_multiuser_model located in the model folder defines whether the model is a multi-user or a single-user model. The file includes also the name of the server. You can open the file using any standard text editor. For more information on the multi-user mode, see Multi-user Mode.

Creating a new model When you first open Tekla Structures, only some icons such as New and Open are active. To create a new Tekla Structures model: 1.

Click File > New... or . The New dialog box appears. You can only have one model open at a time. If you already have a model open, Tekla Structures prompts you to save that model.

2.

In the New dialog box, define the folder to save the model in. By default, Tekla Structures saves models in the folder you specified when you installed Tekla Structures. If you want to save the model in another folder, click Browse... to browse for the model folder, or use the Save in list box with the recently used folders. For more information on how to change the default model folder, see XS_RUNPATH in the System Manual.

3.

Enter the model name.

4.

In the Model type list box, select either Single-user or Multi-user.

5.

If you select Multi-user, enter the server name, or select a recently used server from the Server name list box. See also Overview of the multi-user system in the System Manual.

6.

Click OK to create the new model. The remaining icons become active and the model name appears in the title bar of the Tekla Structures window.

Every model must have a unique name. Tekla Structures does not allow duplicate model names. Do not use special characters ( / \ ; : | ) in model names.

You can use model templates as a basis when you create new models. For more information on creating model templates, see the Tekla Structures 14.0 Administrator’s Guide.

Defining the work area and shifting the work plane Work area

You can define the work area to suit particular situations, for example, to concentrate on a particular area of the model. You can shrink and expand the work area by picking the corner points of the new work area, or size the work area to include selected parts, or all model objects. You can define the work area in a selected view, or in all visible views. To define the work area, use a command from the View menu:

Command

Work plane

Icon

Description

Fit Work Area Using Two Points

Sets the work area based on two corner points you pick on the view plane. The depth of the work area is the same as the view depth.

To Entire Model in All Views

Fits the work area to include all model objects in all visible views.

To Entire Model in Selected Views

Fits the work area to include all model objects in the selected views.

To Selected Parts in All Views

Fits the work area to include the selected model objects in all views.

To Selected Parts in Selected Views

Fits the work area to include the selected model objects in the selected views.

The current work plane defines the local coordinate system of a Tekla Structures model. You can set the work plane to any position by picking points, parallel to one of the global basic planes, or on a part or view plane. The current work plane is model-specific, so it relates to all views. When modeling sloped parts, shifting the work plane helps you to place parts accurately. To shift the work plane, use the icons on the View toolbar, or select a command from the View menu. The following table lists the commands for setting the work plane, and gives a short description of each one:

Command

2.2 Grids Introduction

So that you can easily locate objects in your model, we strongly advise that you create a modular grid. The Tekla Structures grid is shown on the view plane by dash-and-dot lines. See also View plane (p. 56). You can have more than one grid in a model. You may want to create a large-scale grid for the entire structure, and smaller grids for some detailed sections. Grids are rectangular. You can also create single grid lines and attach them to an existing grid.

50





To position objects in a radial or circular pattern:

•

Create one grid line and use the Edit > Copy Special > Rotate command to copy it.

•

Use construction lines and circles. See Construction planes, lines, and circles (p. 62).

You can pick grid lines and grid line intersections. See also Specifying points (p. 33).

Grid properties To access the Grid dialog box, do one of the following:

Grid coordinates

•

Click Modeling > Create Grid....

•

Use the Select grid switch

and double-click an existing grid.

The x and y coordinates of a grid are relative. This means that the entries for x and y are always relative to the previous entry. The z coordinates are absolute meaning that entries for z are absolute distances from the work plane origin. There are two ways to enter the x or y coordinates of grid lines:

• •

individually, e.g. 0 4000 4000, or several grid lines with equal spacing, e.g. 0 2*4000.

Both create three lines with the spacing of 4000.

Use a zero at the start to represent a grid on the 0,0 coordinate and spaces as separators for coordinates. You can have a maximum of 1024 grid characters in the co-ordinates field.

Labels are the names of the grid lines shown in views. The names in the X field are associated with the grid lines parallel to the y axis and vice versa. The Z field is for the names of levels parallel to the work plane. If you wish, you can leave the label fields empty.

Labels

When working with very large grids, having the grid labels always visible might slow down Tekla Structures. To hide the grid labels when you zoom in, use the variable XS_ADJUST_GRID_LABELS.

Line extensions

www.cadfamily.com

You can also define the Line extensions over the given grid coordinates and the Origin of the grid.




51

Line extensions Work plane origin Grid labels Magnetism

You can make grids and grid lines act magnetically so that the objects on the grid lines follow if you move the grid line. To bind objects to grid lines, select the Magnetic grid plane checkbox. In the Extension for magnetic area field, enter a distance from the grid line to extend the area within which the objects are bound to the grid lines.

Grid line properties You can also create and modify single grid lines. To access the Grid Line Properties dialog box:

•

Use the Select grid lines switch

and double-click an existing grid line.

Working with grids Automatic grid

When you create a new model, Tekla Structures automatically creates a grid and a view according to the saved standard properties.

3.

To create the grid, click the Create button.

Tekla Structures prompts you to pick the origin when you create the grid. Pick a point in a view, and the coordinates of the picked point appear in the Grid dialog box as X0, Y0, and Z0. If you do not pick, Tekla Structures positions the origin according to the values you entered for X0, Y0, and Z0.

Creating grid lines To manually create a grid line: 1. 2.

Click Modeling > Add Grid Line. Select an existing grid to which to attach the grid line.

3.

Pick the starting point of the grid line.

4.

2.3 Views Introduction

There are several ways to create views in Tekla Structures. For example, you can create views:

• •

of the entire structure

•

along the grid lines

of selected part(s) and component(s)

Each view has properties which define its appearance. You can change the appearance of a view after you create it so choose the creation method that suits you. This section describes the viewspecific properties. You can open the view properties dialog box for each view, to view or modify the properties.

Unnamed views disappear when you close them. See Naming views (p. 56).

You can have up to nine views on the screen at the same time. If you try to open more than nine views, Tekla Structures displays a warning. If the view does not appear, check how many views you have open.

To switch between views, press Ctrl+Tab.

www.cadfamily.com




55

View plane Each view has a view plane on which the grids are visible and points are represented as yellow crosses. Basic view plane

Basic views are those parallel to the global basic planes, i.e. xy, xz, and zy. In basic views two axes always define the view plane and they appear in the plane name. The third axis is perpendicular to the view plane. It does not appear in the plane name. In the basic plane view, the model is shown from the direction of that third axis. The view plane options for basic views are:

View plane coordinate

For basic views, you also define at which distance from the global origin the view plane is in direction of the third axis. The view plane coordinate equals this distance.

Other views

For view types other than basic views, you define the view plane and coordinate by picking points, e.g. With three points, or they are defined automatically according to the chosen creation method/command, e.g. To work plane.

Moving the view plane

You can change the view plane by moving it like any other object. Click anywhere on the plain background, right-click and select Move Special > Linear... from the pop-up menu. See Copying and moving objects (p. 138) and Move (p. 140).

Moving a view plane may result in a situation such that view depth and work area do not intersect and thus nothing can be seen in the window.

View properties Naming views

Tekla Structures numbers views in order of creation, so you do not have to give each view a specific name. You should give a view a unique name if you need to open it in later sessions. See Opening, closing, and deleting named views (p. 60). When you exit the model, Tekla Structures only saves named views. Tekla Structures does not save unnamed views when you close them.

In multi-user mode, it is very important to give views unique names. If several users have different views with the same name, the view settings of one user may randomly override the settings of another user.

56





View type The view type defines the appearance of the view. It also affects what methods you can use to rotate the model. The view type options are:

•

Wire frame

Objects are transparent and their outlines are displayed. As the wire frame views use line graphics technique, redrawing views is quick.

•

Rendered

Objects look more realistic because they are non-transparent and their surfaces are displayed as shown in the illustrations below. However, you can also choose the Wireframe or Shaded Wireframe option in the rendered views. Rotating the model in the rendered views is very convenient with the mouse.

Representation In rendered views, you can define how Tekla Structures displays parts and component objects separately. The following options are available:

•

Wireframe

Part outlines are displayed, surfaces are not, i.e. parts are transparent. (In this example, component objects are displayed as Rendered.)

•

Shaded Wireframe

Part outlines are displayed. Parts are transparent, and their surfaces are shaded. (In this example, component objects are displayed as Rendered.)

•

Hidden Lines

Parts are not transparent, i.e. underlying parts are not visible. Part surfaces are not displayed.

www.cadfamily.com




57

•

Rendered

Part surfaces are displayed, i.e. parts are not transparent.

•

Rendered (Dark Colors)

Parts are not transparent. Part outlines are displayed with brighter color, and part surfaces with darker color than in the Rendered option.

In rendered views, use the shortcuts Ctrl+1...5 and Shift+1...5 to set the desired representation for parts in the model and components.

For more information on how objects are shown in views, see Displaying and hiding objects (p. 143).

Projection If you choose the rendered view type, the projection can be:

•

Orthogonal

All objects are of equal size (no perspective). When you zoom, text and point size remains the same. In addition, the zoom remains on part surfaces.

•

Perspective

Distant objects appear smaller than close ones, as do text and points. You can zoom, rotate the model, or fly through it. View angle

Views can be:

• •

Plane 3D

Use the shortcut Ctrl+P or click View > Switch to 3D / Plane to switch between 3D and plane view.

Rotation

58

Rotation is view-specific. You can rotate the model in 3D views using the mouse and keyboard (see Rotating the model (p. 129)), or by defining the rotation angle in the View properties dialog box. You can specify rotation angles around the z axis and around the x axis.





Every view has depth, which is the thickness of the displayed slice of model. You can define the depth separately upwards and downwards from the view plane. The objects within the displayed depth and the work area are visible in the model. However, objects created after the view are visible also outside the view depth. See Displaying and hiding objects (p. 143).

View depth

Defining grid view properties Grid views are views along the grid lines. Before creating grid views, you can define how many views Tekla Structures will create, how it will name the views, and which view properties it will use. Number of views

There are four options for the number of views:

•

None

Tekla Structures does not create any views.

•

One (First)

Tekla Structures only creates the view closest to the grid origin.

•

One (Last)

Tekla Structures only creates the view furthest from the grid origin.

•

All

Tekla Structures creates all views in grid planes in the relevant direction. View name prefix

View names consist of a prefix and a grid label, e.g. PLAN +3000. If the View name prefix field is left empty, no prefix is used. Tekla Structures adds a dash and a running number to the view name if view names are otherwise identical.

View properties

Each view plane has its own view properties. See View properties (p. 56). You can load the properties from the current view properties with the option or from saved view properties. The Show… button displays the view properties.

Creating and modifying views When you create a new model, you can select the Create default view and grid checkbox to have Tekla Structures automatically create a grid and a view according to the saved standard properties. Creating

To create views, use the commands on the View menu. The following table lists the commands for creating views and gives a short description of each one:

See also Using windows (p. 22).

2.4 Points Introduction

To place an object in a model you may need to pick points. To place an object where no lines or objects intersect, you have the following options to place objects:

• •

Use snapping commands. See Snapping (p. 177). Use construction planes, lines and circles. See Construction planes, lines, and circles (p. 62).

•

Create points.

There are many ways to create points in Tekla Structures. Which method is the most convenient at each time, depends on what you have already created in the model and which locations you can easily pick. When you create points, Tekla Structures always places them according to the work plane coordinate system. Points located in the view plane are yellow and points outside the view plane are red.

Point properties To view the properties of a point, double-click the point or click Tools > Inquire > Object and select the point. See also Inquire (p. 132). Phase and ID

Just like any other object, each point has an ID number which is used in log files. Points and parts have phase numbers. You can filter objects by their phase and ID numbers. See Selection filter (p. 153).

Coordinates

The point information you are most probably interested in is the local (work plane) and global x, y, and z coordinates of a point. Checking them convinces you of the correct location of the point or some other object related to it.

Creating points To create points, use the icons on the Points toolbar, or select a command from Modeling > Add Points. The following table lists the commands for creating points and gives a short description of each one:

Command

2.5 Construction planes, lines, and circles Construction planes, lines, and circles help you place other objects. For example, you can easily pick the points at intersections of construction lines and circles. The snap priority of construction objects is the same as with the other lines. Construction objects remain in the model when you update or redraw views and windows. They do not appear in drawings. To create construction objects, use the icons on the Points toolbar or select a command on the Modeling menu. The following table lists the commands for creating construction objects and gives a short description of each one:

Introduction

Parts

In Tekla Structures, we use the term parts to refer to the basic components of a model. These are the building blocks of the physical model. For structural analysis purposes, we use the term members to mean load-bearing parts. The main concrete parts are:

• •

beam

•

column

•

pad footing

•

strip footing

•

panel

•

3.1 Part properties Introduction

Every part has properties which define it (e.g. material, profile, location, etc.). This section describes the basic part-specific properties. Use the part properties dialog box to view or modify the properties of a part.

Filtering by properties

You can use part properties in filters. For example, you can select, modify, or hide parts based on their properties. See Filter (p. 152).

In reports and drawings

You can include part properties and user-defined attributes in drawing and report templates.

Name

The name of the part is user-definable. Tekla Structures uses part names in reports and drawing lists, and to identify parts of the same type, e.g. beams or columns.

Parts www.cadfamily.com



Finish

Finish is user-definable. It describes how the part surface has been treated, e.g. with anticorrosive paint, hot galvanized, fire retardant coating, etc.

Class

Use Class to group parts. To display parts of different classes in different colors, click View > Representation > Object Representation... and select Color by class in the Color list box. See also Colors (p. 166).

Profile Tekla Structures contains standard, parametric, and user-defined profiles. Standard profiles

When you first start Tekla Structures, the profile catalog contains standard, environmentspecific profiles. The properties of these library profiles conform to industry standards, so you should not edit them. You can add profiles to the profile catalog. See The profile catalog in the online help.

Parametric profiles

Parametric profiles are partly user-definable, they have a predefined shape, but you determine their size by giving one or more parameters. You can use parametric profiles to closely “model” profiles that are standard in specific environments, but do not exist in the Tekla Structures profile catalog. Parametric profile names have specific prefixes and include dimension values. These are described in Appendix A, Parametric Profiles (p. 221). If you want to define alternative prefixes for parametric profiles, see Customizing parametric profiles in the online help. Dimension values in parametric profile names are separated by standard separators -, X, /, or *. If you want to define additional separators, see XS_PARAMETRIC_PROFILE_SEPARATOR and XS_USER_DEFINED_PARAMETRIC_PROFILE_SEPARATORS in the online help.

User-defined profiles

You can also create your own profiles and save them in the profile catalog. For example, you could create a user-defined profile pitched, with different cross sections at the beginning and end of the profile. You can also define cross sections. To create user-defined cross sections, you pick the points which define the cross section corners. To create your own profiles, see Sketching and using cross sections (p. 195) and Adding a standard (fixed) user-defined profile in the online help.

Selecting a profile To select the profile of a part, click Select... next to the Profile field in the part properties dialog box. The Select Profile dialog box appears.

www.cadfamily.com




67

Standard profile Parametric profile You can select a profile from the tree which lists profiles contained in the profile catalog. Profiles are grouped in the tree according to rules (such as profile type) which you can define and modify. Only the profile types that are relevant to the material of the part are shown. For more information on how to modify the profile catalog and rules, and how to associate profile types with materials, see The profile catalog and Working with rules in the online help. If you select a parametric profile, enter the profile dimensions in the Value column. All profiles and details

If you select the Show all profiles checkbox, Tekla Structures includes all the profiles in the profile catalog in the tree. To see all the properties of profiles, select the Show details checkbox. For user-defined profiles Tekla Structures also displays cross section information. When you have selected a profile, click Apply or OK.

68





You can also:

•

Use the Profile name list box in the Select profile dialog box to select a recently used profile.

•

Enter a profile name in the Profile field in the part properties dialog box. Parametric profile names must be in the format shown in Appendix A, Parametric Profiles (p. 221).

Using standardized values for profile dimensions You can define standardized values for the dimensions of parametric profiles in the industry_standard_profiles.inp file in the ..\environments\*your_environment*\system folder. To use these values, in the Select profile dialog box, select a parametric profile for which you have defined standardized values and select the Use industry standardized values only checkbox. You can select the profile dimensions from a list box in the Value column. You can edit the industry_standard_profiles.inp file using any standard text editor (for example, Notepad). Use the following format:

Example

• •

Profile and profile subtype

•

Units for each parameter

•

Standardized values for each parameter (own row for each dimension combination)

Parameters separated by spaces

In the following example we define standardized combinations of dimension values for a C profile:

industry_standard_profiles.inp C h*b*t h b mm mm 75 35 75 35 75 35 100 40 100 40 100 40

t mm 5 6 7 7 8 9

Material The material catalog contains standard, environment-specific materials. You can add, modify, and delete materials and grades.

Defining the material of a part Select...

www.cadfamily.com

To select the material of a part, click Select... next to the Material field in the part properties dialog box. The Select material dialog box appears. You can select the material and grade from the tree, which displays all the materials in the material catalog.




69

Aliases and details

To include aliases for material grades in the tree, in the Select material dialog box, select the Show aliases checkbox. Aliases are alternative names. For example, they can be former names, or names used in different countries or standards. Tekla Structures automatically translates aliases into the standard name when you select a material grade. To see all the properties of materials, select the Show details checkbox.

Analysis

The Analysis tab contains information on the properties used in structural analysis, including the modulus of elasticity, Poisson’s ratio, and thermal dilatation coefficient.

Design

The Design tab contains information on design-specific properties, such as strengths, partial safety factors, etc.

User attributes

Use the User attributes tab to view or modify the user-defined properties of materials. For example, this tab could contain the maximum grain size, porosity, or surface quality class of a concrete material type, or country-specific properties. When you have selected the material for a part, click Apply or OK.

70





You can also enter a material name in the Material field in the part properties dialog box.

To modify the material catalog, see The material catalog in the online help.

User-defined attributes User-defined attributes provide extra information about a part. Attributes can consist of numbers, text, or lists. The following table explains what you can use attributes for:

Attribute

Can be used...

Comment

In part and weld marks in Tekla Structures drawings, or in projects.

Shorten

When drawings of the parts are created, Tekla Structures decreases the true length of the part by this value. This is useful when creating assembly drawings of bracing bars which should always be under tension.

Camber

In part marks in Tekla Structures drawings.

Prelim mark

To obtain preliminary marks for parts in reports. To assign part position numbers to preliminary marks, click Drawings & Reports > Numbering > Save Preliminary Numbers when you number parts. To check the preliminary mark of a selected object, click Tools > Inquire > Object.

Shear, Tension, and Moment

To save reaction forces for AutoDefaults. See AutoDefaults settings and Reaction forces and UDL in the online help. You can enter forces separately for each end of a part.

Locked

To protect objects from being accidentally changed. See Locking objects in the online help.

User field 1...4

User-defined fields. You can change the names of these fields and add new user-defined fields. See Adding properties in the online help.

Connection code

When importing information on connection types into Tekla Structures. You can then use the connection codes as rules in AutoConnection and AutoDefaults. Each end of a part can have a different connection code.

For more information on defining attributes using the objects.inp file, see Adding properties in the online help.

3.2 Cast units and assemblies Steel assemblies

Tekla Structures creates basic assemblies of steel parts when you use a workshop weld or bolt to join parts. Assemblies and their main parts are automatically defined when you:

• •

Create single workshop welds or bolts. Apply automatic connections which create workshop welds or bolts.

See also Detailing (p. 105). You can also create nested assemblies by adding sub-assemblies to existing assemblies, or by joining assemblies together. See Working with assemblies (p. 74). Concrete cast units

The concrete structures in Tekla Structures are modeled as single parts. By default, each part is considered a separate cast unit. For construction purposes you may need to merge several concrete parts into one cast unit. For example, a single cast unit could consist of a column with corbels. You need to specify which parts form the cast unit. Cast units can include reinforcement, as well as concrete parts. See Working with cast units (p. 77).

Main parts

The main part in a steel assembly has other parts welded or bolted to it. By default, the main part is not welded or bolted to any other parts. The main part in a concrete cast unit is the one with the largest volume of concrete. You can change the main part in an assembly or a cast unit. See Changing the assembly or cast unit main part (p. 79).

Checking contents

To visually check the objects in a cast unit or an assembly, click Tools > Inquire > Assembly Objects. Select a part in the cast unit or assembly. Tekla Structures highlights the other parts that belong to the same cast unit or assembly. See also Inquire (p. 132). Tekla Structures uses different colors to highlight different objects:

Object type

Highlight color

Concrete – main part

magenta

Concrete – secondary part

cyan

Reinforcement

blue

Steel part – main part

orange

Steel part – secondary part

yellow

To check the sub-assemblies in a nested assembly, right-click the assembly and select Assembly > Show Assembly from the pop-up menu. Tekla Structures draws an orange box around each assembly.

To select an entire cast unit or assembly:

• •

Use the Select assemblies switch

Hold down the Alt key and select one of the parts in the cast unit or assembly.

See also How to select objects (p. 36).

72



, or



Drawings and reports

You can also produce drawings and reports for cast units and assemblies. See Cast-unit drawing, Assembly drawing, and Printing reports in the Drawing Manual. Assembly hierarchy in nested assemblies affects drawings and reports. You can create separate drawings and reports of the sub-assemblies and the nested assembly, and still produce dimensions, marks, fabrication information, etc. for all assembly levels.

Assembly examples •

A column corbel is fabricated in one workshop, and then attached to the column in another workshop. Model the corbel as a sub-assembly of the column. Then create an assembly drawing for each workshop: one assembly drawing showing how the corbel is welded together, another assembly drawing showing how the corbel and the other part are welded to the column.

Drawing 2, Workshop 2 Drawing 1, Workshop 1

www.cadfamily.com

•

Model the halves of a complex truss as assemblies. Create assembly drawings for the workshop to fabricate the truss halves. Then create another assembly drawing showing how the halves should be joined on site.

•

In a frame of built-up columns and beams, each built-up profile can be a sub-assembly. You can create an assembly drawing showing the entire frame and separate drawings showing how the columns and beams are built up.




73

Working with assemblies You can modify assemblies by:

• •

Adding objects to assemblies (p. 75)

•

Removing objects from assemblies (p. 76)

•

•

Changing the assembly or cast unit main part (p. 79)

•

Changing the main assembly (p. 79)

Creating sub-assemblies of assembly parts (p. 76)

To work with nested assemblies, you need to know how to use the Shift key and mouse scrolling to select objects on different levels in assembly hierarchy. See How to select objects (p. 36) and Controlling the selection (p. 38). You can work on any level of a nested assembly, from single parts and bolts, through the basic and sub-assemblies, up to the highest level of the nested assembly:

3.3 Numbering parts This section discusses the principles you need to consider when planning numbering. Tekla Structures uses numbers to identify parts, cast units, and assemblies when producing drawings and reports, and exporting models. You must have Tekla Structures number the model parts before you can create single-part, assembly, cast unit, and multdrawings, or some export files from a model. Tekla Structures uses part numbers in many tasks, for example:

Introduction

• •

Connecting a drawing with the right part, cast unit, or assembly.

•

Identifying part information for export another program.

Reporting the properties of identical parts, cast units, and assemblies.

See Numbering (p. 168) for information on how to set up and carry out numbering.

Defining numbers to be used for parts Numbering series

You use a numbering series to divide steel part, cast unit, and assembly numbers into groups. For example, you can allocate separate numbering series to different phases or part types. You can name the numbering series to which a part, cast unit, or assembly belongs, using the part properties dialog box. The numbering series name consists of a prefix and a starting number.

Example

www.cadfamily.com

For example, if you define a numbering series with the prefix P and starting number 1001, Tekla Structures numbers that series P1001, P1002, P1003, ...




79

By default, the steel part mark prefix is P, the concrete part prefix is Concrete, and the starting number is 1. You do not have to specify a part prefix (for example, you may want to omit the part prefix for minor parts). When you run numbering (see Numbering (p. 168)), Tekla Structures compares parts that belong to the same series with each other. All identical parts in the same numbering series are given the same part number.

By default, a part retains its number, as long as only one part has that particular number, regardless of the settings in the Numbering setup dialog box.

Cast units andassemblies

Tekla Structures numbers concrete cast units and steel assemblies using the same principles as it follows when numbering parts. The default starting number is 1. The prefix varies based on the part type.

Assembly and cast unit numbering may affect part numbering, if the variable XS_USE_ASSEMBLY_NUMBER_FOR is set.

Part numbering does not affect cast unit and assembly numbering. For more information on cast units and assemblies, see Cast units and assemblies (p. 72). Overlapping series

When planning numbering, ensure that you reserve enough numbers for each series. If one series overflows into another, Tekla Structures might allocate the same number to different parts. Tekla Structures warns you about series overlaps. View the numbering history log to check which numbers overlap. See Log files in the online help.

What affects numbering Identical parts

Tekla Structures treats parts as identical, and so gives them the same number, if the following basic part properties are the same:

Part property

Condition

Part geometry

Including the location, size, and number of holes, if you select the Holes checkbox in the Numbering setup dialog box. Tekla Structures gives parts the same number if the parts are identical in the fabrication or casting. If a part is deformed after fabrication or casting (for example if the part is cambered, shortened, or warped), the final geometry on site and in the model may be different.

Numbering series Name

If you select the Part name checkbox in the Numbering setup dialog box.

Profile

80





Part property

Condition

Material Finish Class and phase do not affect numbering. Tekla Structures gives the same number to identical parts that belong to different classes or phases.

You can set the degree of tolerance for part geometry in the Numbering setup dialog box. If the geometry of parts differs within this degree of tolerance, Tekla Structures treats the parts as identical for numbering purposes. Tekla Structures treats parts as different, and so numbers them differently, if the following properties differ:

Additional properties

Property

Condition

User-defined attributes

If a user-defined attribute has the variable special_flag set to yes, Tekla Structures takes this user-defined attribute into account when numbering. For more information on defining user-defined attributes, see Adding properties and Interpreting objects.inp in the online help.

Pop marks

E.g. if two parts have different pop marks, or one part has pop marks and the other one does not, Tekla Structures gives the parts different numbers. See Pop marks in the online help.

Beam orientation

If you select the Beam orientation checkbox in the Numbering setup dialog box.

Column orientation

If you select the Column orientation checkbox in the Numbering setup dialog box.

Reinforcement

If otherwise identical concrete parts have different reinforcement and if you select the Reinforcing bars checkbox in the Numbering setup dialog box, Tekla Structures gives the parts different numbers. See Reinforcement and Numbering reinforcement.

Cast-in embeds

If you select the Embedded objects checkbox in the Numbering setup dialog box.

Surface treatment

If you select the Surface treatment checkbox in the Numbering setup dialog box.

Cast units and assemblies

Tekla Structures numbers cast units and assemblies in the same way as it does parts. The orientation of assemblies also affects numbering if you select the Beam orientation and Column orientation checkboxes in the Numbering setup dialog box.

3.4 Part location In this section

This section describes the part position properties that vary according to the part type.

Part reference point

When you create a part, you position it by picking points. These are the part reference points. The position of a part is always relative to its reference point(s).

Part reference line

If you pick two points to position a part, these points form the part reference line, and handles appear at the line ends.

When creating horizontal parts, it is worth being consistent and always picking points from left to right, and from bottom to top. This ensures that Tekla Structures places and dimensions the parts in the same way in drawings, and that part marks automatically appear at the same part end. To see the part reference line in the model: 1. 2.

Click View > View Properties.... Click the Display... button to open the Display dialog box.

3.

On the Advanced tab, select the Part reference line checkbox.

4.

Click Modify and OK.

You can use part reference lines to help snapping to the middle points of parts, for example.

Handles

Tekla Structures indicates the direction of a part with handles. When you select a part, the handle at the first end is yellow, and the handle at the second end is magenta.

You can use handles to move the part end: 1.

82

Select the part to display the handles.





2.

Click the handle you want to move. Tekla Structures highlights the handle.

3.

Move the handle(s) like any other object. See Move (p. 140). If you have Drag and drop on, just drag the handle to a new position. See Drag and Drop (p. 142).

By default, the handles of contour plates and concrete slabs are not visible. To show them, set the variable XS_DRAW_CHAMFERS_HANDLES to HANDLES.

See also

For more information on selecting handles, see How to select objects (p. 36).

Position on work plane You can define the position of a part on the work plane as:

• •

Middle

•

Left

Right

You can also define the distance of a part from its original reference line. See Part reference point (p. 82). Beam

An example of the options for beams:

Middle Left Right Middle 200 Left 200 Right 200

www.cadfamily.com




83

Position depth You can define the position of a part in terms of its depth, perpendicular to the work plane, as:

• •

Middle

•

Behind

Front

An example showing the options for beams:

Beam

Work plane Middle Front Behind Middle 100 Front 100 Behind 100 Contour plate

84

Work plane Middle Front Behind

Rotation You can define the rotation of a part around its axis on the work plane as:

• •

Front

•

Back

•

Below

Top

You can also define the angle of rotation. Tekla Structures measures positive values clockwise around the local x axis. Beam

86





Vertical position You can define the vertical position of a part, relative to its reference point, as:

Column

• •

Middle

•

Up

Down


Middle Down Up Middle 100 Down 100 Up 100

Horizontal position You can define the horizontal position of a part, relative to its reference point, as:

Column

www.cadfamily.com

• •

Middle

•

Right

Left





87

Middle Left Right Middle 100 Left 100 Right 100

End offsets Use end offsets to move the ends of a part, relative to its reference line. You can enter positive and negative values. The options are:

Field

Result

Dx

Changes the length of the part by moving the part end point along the reference line

Dy

Moves the part end perpendicular to the reference line

Dz

Moves the part end in the z direction of the work plane

Levels For parts that you create by picking only one point (e.g. columns), you can enter the positions of the part ends, relative to the picked point, in the global z direction. Use Bottom to define the position of the first end. Use Top to define the position of the second end.

Bending In Tekla Structures, you create curved parts by defining a radius and the plane of curvature.

88





When you create a curved part, you pick three points to define the radius. You can also enter a specific value for the radius in the part properties dialog box.

Radius

The sector angle must be less than 180 degrees.

The plane of curvature is relative to the current work plane. The options are:

Plane

• • Number of segments

xz plane xy plane

To have Tekla Structures draw a curved part, you need to specify a number of segments. Tekla Structures does not show curved surfaces exactly in views, instead the number of segments determines how realistic the curved part looks: the more segments, the less angular the part appears. If you specify a large number of segments it affects how quickly Tekla Structures draws the model. See also How handles solids in the online help.

3.5 Surface treatment This section explains how to create various surface treatments and finishes for steel and concrete parts. It contains the following topics:

• •

Adding surface treatment to parts (p. 89)

•

If you use the To All Faces of Part command and select the Cut by father part cuts checkbox, Tekla Structures automatically adds surface treatment also to the cut faces.

Cutting surface treatment

To define the cut depth of a polygon cut, for example, to cut thick surface treatment, use the variable XS_POLYGON_CUT_EXTRA_THICKNESS: 1. 2.

Click Tools > Advanced options..., and go to the Modeling properties category. Set the cut thickness for the variable XS_POLYGON_CUT_EXTRA_THICKNESS. The default value is 5.0 mm.

Adding surface treatment to chamfered parts Take these things into account when adding surface treatment to chamfered parts:

• •

Surface treatment does not work on sketched profiles with chamfers.

•

The chamfers for the main part and surface treatment are separate. Modifying the main part chamfer does not affect the surface treatment chamfer.

•

The orientation of unsymmetric chamfers depends on the face where it was created (such as top, bottom, left, or right). To change the orientation of an unsymmetric chamfer, you must swap the chamfer's x and y values.

Add surface treatment before chamfering the part. If surface treatment is applied to a chamfered part, the surface treatment chamfer cannot be modified later on.

Creating and editing surface treatment options To create new options in the Surface treatment name list box in the Surface treatment properties dialog box, or to edit existing names, edit the product_finishes.dat file, located in the ..environments\*your_environment*\system folder.

Detailing

After you have created a frame of parts in your Tekla Structures model, you will need to complete the model by connecting these parts and adding minor parts and details.

Introduction

This section explains how to create details (bolts, welds, etc.) using Tekla Structures. It also gives you some techniques for “fine-tuning” part shape and an overview of detailing commands. You can find step-by-step instructions for all these commands in the online help. This section includes the following topics:

Contents

• •

Bolts (p. 105)

•

Fine-tuning part shape (p. 119)

•

Detailing commands (p. 124)

Welds (p. 112)

4.1 Bolts Introduction

There are two ways to create bolts:

• •

Create a single bolt group Apply a component that automatically creates bolt groups.

This section concentrates on creating single bolt groups. For more information on using components to automatically create bolt groups, see Defining bolts and welds in the Detailing Manual. You can create different part marks for holes and bolts in drawings. You cannot use bolt elements (such as screws, washers, and nuts) while you are creating holes, as Tekla Structures uses the same command to create bolts and holes. Creating assemblies

You can use bolts to create and connect assemblies. You can create nested assemblies by connecting sub-assemblies to an existing assembly, or you can just connect more parts to assemblies using bolts. Use the Connect part/assembly and Bolt type list boxes in the Bolt properties dialog box to control how Tekla Structures creates assemblies. The order in which you select parts when

Site

No assembly created.

For more information on creating assemblies, see Cast units and assemblies (p. 72). Bolt catalog

Tekla Structures treats bolts as pre-defined assemblies made up of individual elements (bolts, washers, nuts, etc.). Tekla Structures stores bolt assemblies in the bolt assembly catalog. The individual elements (bolts of different size and length, nuts, washers, etc.) are contained in the bolt catalog. For more information on catalogs, see Bolt and bolt assembly catalogs in the online help.

Creating a bolt group See Bolt in the online help for detailed instructions on how to create a bolt group. Work plane

The work plane only affects the rotation of the bolt group. The points you pick determine the position of the bolt group.

Bolted parts

It is important that the points you pick to create the bolt group are close enough to the parts you want to connect. The cut length property of a bolt group defines how far along the bolt axis the parts must be in order to hit the bolt group.

Bolt group origin

Dimensions are relative to the bolt group origin, which is the first point you pick when creating a bolt group. Tekla Structures sets the x direction of a bolt group using the second point picked. These points are shown as crosses in the illustration below. The dashed line indicates the x direction.

Creating by modifying (p. 107)

Creating by modifying You can also create a new bolt group by modifying an existing one. In most cases it is easier to create bolt groups by applying a component including bolt groups, using the following method: 1. 2.

Apply a component. Explode the component.

3.

Modify the bolt group.

Changing bolted parts You can change which parts a bolt group connects using the command Detailing > Bolts > Edit Bolted Parts. This command prompts you to reselect the main and secondary parts. Tekla Structures automatically updates bolt length to suit these changes. For more information, see Bolt length calculation in the online help.

Creating holes Tekla Structures creates holes in the same way as bolts, but you do need to change some of the properties in the Bolt properties dialog box. You can create the following types of holes:

• •

Round

•

Slotted

•

Tapped

Oversized

Creating round holes To create a round hole, follow the steps in Creating a bolt group (p. 106). Tekla Structures calculates the diameter of a round hole as the sum of:

• •

Bolt size Tolerance (hole)

To only create a hole, clear all bolt element checkboxes in the Bolt properties dialog box, as shown below:

www.cadfamily.com




107

Clean these checkboxes to create a mere hole

Creating slotted holes You also use the Bolt properties dialog box to create slotted holes. 1.

Select the checkboxes against Parts with slotted holes to indicate which parts should be slotted. Tekla Structures counts the pieces of steel from the head of the bolt down. For example, if you select the second checkbox from the head of the bolt, Tekla Structures slots the second piece of steel from the head of the bolt.

2.

To only create a slotted hole, clear all the Include in bolt assembly checkboxes.

3.

Select Slotted in the Hole type list box.

4.

Enter the allowance for the slotted hole in the x and y directions of the bolt group using the Slotted hole X or Slotted hole Y fields.

Tolerance Slotted hole X or Y Bolt size

108





You indicate the x direction of the bolt group when you create the bolt group (see Creating a bolt group (p. 106)).

5.

If the bolt connects several parts, you may want to rotate alternate holes by 90 degrees. This allows the bolt to move in different directions. To do this, select Even or Odd in the Rotate slots list box.

Crossing slotted holes to odd or even parts Parallel slotted holes

Creating oversized holes Use the Bolt properties dialog box to create oversized holes. 1. 2.

Select the checkboxes against Parts with slotted holes to indicate which plies of connection get oversized holes. To only create a hole, clear all the Include in bolt assembly checkboxes.

3.

Select Oversized in the Hole type list box.

4.

Enter the allowance for the oversized hole in the Oversize field. You can also use a negative value to create smaller (tapped) holes.

Bolt group shape You have the following options for bolt group shape:

• •

Array for rectangular

•

Circle for circular

xy list for any shape

Tekla Structures uses the values in Bolt dist X and Bolt dist Y to determine how many bolts the bolt group contains, as shown in the table below:

Single bolt

Bolt dist X

Bolt dist Y

Array

Spacing between bolts, in the x direction of the bolt group.

Bolt properties

The bolt properties are:

Field

Description

Bolt size

Bolt sizes available in the selected bolt standard.

Bolt standard

Bolt assembly standard, which is defined in the bolt catalog.

Bolt type

Indicates if bolts are assembled on-site or in the shop.

Bolt length Tekla Structures calculates bolt length automatically, using the material thicknesses of the connected parts, and other factors. The following settings in the Bolt group properties dialog box affect bolt length calculation:

• •

Thread in material

•

Extra length

Cut length

Thread in material indicates if the thread of the bolt can extend beyond the bolted parts. Tekla

Structures does not use this value when calculating the length of full-threaded bolts. Cut length indicates the area Tekla Structures should search for parts that belong to the bolt group. Using cut length you can determine whether the bolt will go through one flange or two. In the illustration below, A is the cut length and B is the bolt origin. Tekla Structures calculates the search area as A/2 in both directions from point B.

Tekla Structures warns you if the cut length is too small (i.e. the bolt group contains no parts) and makes the bolt length 100 mm.

If you want to force a bolt to be a certain length, enter a negative value for length (e.g. -150).

110





Using Extra length to increase the material thickness Tekla Structures uses when calculating bolt length. For example, you might need extra bolt length to allow for painting. You can also build additional lengths into bolt assemblies .

If there are large gaps between connected parts, the gap is added to the length of the bolt. Tekla Structures calculates bolt length using the the total distance between the first and last surfaces.

Bolt catalog

See also

Bolt length calculation Clash check (p. 134)

Bolt group location Tekla Structures determines the location of the bolt group using the following values:

• •

Bolt group x axis Work plane

The two points you pick to create the bolt group determine the bolt group point of origin and its x direction. Position on plane

Position on plane moves the bolt group perpendicular to the bolt group x axis.

Position at depth

Position at depth moves the bolt group perpendicular to the current work plane.

Rotation

Rotation defines how far the bolt group is rotated around the x axis, relative to the current work

plane. For example, you can use this field to indicate on which side of the connected parts you want the bolt head to be.

Front Top Offsets

You can also use offsets to change the position of the bolt group. Offsets move the bolt group by moving the x axis of the bolt group. The starting point values Dx, Dy and Dz move the first end of the bolt group, relative to the bolt group x axis. The end point values move the second end of the bolt group.

• •

www.cadfamily.com

A positive Dx value moves the starting point towards the end point. Dy moves the end point perpendicular to the bolt group x axis on the current work plane.




111

• Example

Dz moves the end point perpendicular to the current work plane.

4.2 Welds Introduction

To create welds in Tekla Structures, you can:

• • Creating assemblies

Create single welds Apply components that automatically create welds

Tekla Structures forms assemblies based on where the weld should be made. You can create:

• •

Workshop welds Site welds

The Connect part/assembly setting in the Weld properties dialog box also affects assemblies. See Weld properties (p. 115).

Tekla Structures uses the order in which you select the parts when creating the weld to determine the primary and secondary parts of the assembly. This affects drawings. The first part you select becomes the primary part of the assembly. Tekla Structures dimensions secondary part(s) relative to the primary part in assembly drawings. The largest primary part in the weld becomes the main part of the assembly. When you connect assemblies, the first part you select determines the assembly to which you weld sub-assemblies. Visibility in views

To have welds visible in views, open the Display dialog box and set weld visibility to Exact. See Displaying and hiding objects (p. 143). Tekla Structures displays all weld types in a similar way.

Creating welds You can create the following types of welds:

112





•

Regular welds. Tekla Structures welds the two parts together using the weld position in the Weld properties dialog box. The length of the weld depends on the length of the connection between the welded parts.

•

Polygon welds. You define the exact position of the weld by picking the points you want the weld to traverse.

•

Single part welds.

If you move welded parts, polygon welds move with the primary part.

For detailed instructions on how to create welds, see:

Weld symbols in drawings Weld properties

Tekla Structures shows the properties of the weld in the weld symbol in drawings, as shown below. See also Weld properties (p. 115).

Effective throat Root opening Reference line and arrow

The weld symbol also contains a reference line and an arrow. The arrow connects the reference line to the arrow side of a connection.

Arrow and other side

When parts are welded together, you can place welds on:

• •

The arrow sides only

•

Both the arrow and other sides

The other sides only

The welds on the arrow and other sides of a part can have different weld properties. By default, the properties you define for a weld on the arrow side appear above the reference line in drawings. The properties of an other-side weld appear below the reference line in the weld symbol.

To show the arrow-side weld properties below the reference line in a weld symbol and the other-side properties above, use the variable XS_AISC_WELD_MARK.

114





Weld properties This section describes weld properties. See the image below.

Size

Size Root face thickness (RFT) If you enter a zero or negative weld size, Tekla Structures creates the weld, but does not display it drawings. Type

See Weld types (p. 116)

Weld preparation groove angle

When parts are prepared for welding, their edges can be beveled to produce a groove for the weld. This type of weld preparation is commonly used for V-type welds. You can define the angle of bevels and grooves. Tekla Structures displays the angle between the weld type symbol and the fill type contour symbol. For more information on weld preparation, see Weld preparation (p. 119).

Contour

The fill type contour of a weld can be:

Finish

• • •

None

•

Concave

Flush Convex

Tekla Structures displays the finish symbol above the weld type symbol in drawings. The options are:

• •

G (Grind)

•

C (Chip)

M (Machine)

Length

The length of a regular weld depends on the length of the connection between the welded parts. You can set the exact length of a polygon weld by, for example, defining the start and end points of the weld.

Pitch

To create a non-continuous weld, define the center-to-center spacing and the pitch of the welds. Tekla Structures calculates the distance between the welds as the pitch minus the length of the weld.

By default, Tekla Structures uses the character - to separate weld length and pitch, e.g. 50–100. To change the separator to @, for example, set the variable: XS_WELD_LENGTH_CC_SEPARATOR_CHAR=@.

Root face and RFT

www.cadfamily.com

Root face is the height of the narrowest part inside the root opening. The RFT fields in the connection dialog boxes also refer to the root face (thickness).




115

Neither root face nor RFT values appear in drawings, but you can use the WELD_ROOT_FACE_THICKNESS field in reports to show the root face dimension in the weld list. Effective throat

Effective throat is the weld size used in weld strength calculation.

Root opening

Root opening is the space between the welded parts.

Edge/Around

Either one edge (Edge) or the entire perimeter of a face (Around) can be welded. A circle in the weld symbol in drawings indicates the Around option has been used.

Workshop/Site

Tekla Structures indicates site welds in the weld symbol using a flag.

Where weld is to be made (workshop or site), affects assemblies and drawings.


Use the Connect part/assembly and Workshop/Site list boxes in the Weld properties dialog box to control how Tekla Structures creates assemblies. The order in which you select parts when creating the connection determines the main and secondary parts of the assembly, or the assembly hierarchy.

Stitch

To create stitch welds, select Yes in the Stitch weld list box. Stitch welds are staggered on both sides of the part being welded. Tekla Structures shows the weld type symbols as staggered in weld symbols.

User-defined attributes

Create additional properties for welds with user-defined attributes. See Adding properties in the online help.

Reference text and Wtext

To enter additional text for the weld symbol, use the Reference text and Wtext fields. For example, information on the weld specification or process, etc.

Weld preparation When preparing welds, Tekla Structures bevels the parts to be welded using an anti-material cutting part. Tekla Structures subsequently deletes this cutting part. Tekla Structures displays weld preparations using cyan dash-and-dot lines. Some weld types and connections also automatically prepare the parts to be welded. See Weld types (p. 116).

To prevent automatic weld preparation, set the variable XS_DISABLE_WELD_PREP_SOLID=TRUE.

4.3 Fine-tuning part shape Introduction

www.cadfamily.com

This section describes the various tools you can use to fine-tune the shape of a part.




119

Chamfer Some part corners can be chamfered. You can use the Chamfer command to shape the following parts: polybeam, contour plate, strip footing, concrete polybeam, concrete slab, and concrete panel. Tekla Structures creates chamfers using the current properties in the Chamfer Properties dialog box. Click Detailing > Properties > Chamfer... to open the dialog box, or double-click an existing chamfer.

Default chamfer Modified chamfers When Tekla Structures creates a part, by default it has a rectangular chamfer at each corner, which does not change the geometry of the part. To change the shape of a part corner: 1. 2.

Set the chamfer properties. Click Detailing > Create Chamfer.

3.

Pick the corner(s) of the part to be chamfered.

See the online help for more information on using this command.

Fitting Use the Fitting command to fit the part end to a picked plane. You can use fitting to make part shorter, for example.

We recommend to move part Handles (p. 130) to make the part longer.

Fitting symbol This command adjusts the end of a beam on a plane, perpendicular to the view plane, which passes through the cutting line you pick. Tekla Structures displays the fitting in the model using a blue fitting symbol. This command has no effect on contour plates.

Cuts Use cut to shape parts. Cut is not meant for cutting the entire part end. Either move part Handles (p. 82) or use the Fitting (p. 120) command instead. You can create the following types of cuts for a part:

Line cut

• •

Line cut

•

Part cut

Polygon cut

A line cut shapes end of the beam or column. Line cut cuts the end of a beam on a plane, perpendicular to the view plane, which passes through the cutting line you pick. Tekla Structures displays the cut in the model using a blue cut symbol.

121

Exact representation (without symbol) Fast representation (Cut symbol) By default, line cuts do not affect beam length in NC files. To change this, see Fittings affect NC datathe online help. See the online help for more detailed information on using this command. Polygon cut

This command cuts a part using a polygon. Tekla Structures displays the cut using dot-dash lines. You must create cuts in a plane view.

Exact representation (without symbol) Fast representation Polygon-shaped cut

You should always define the polygon so that there is some tolerance between the edges. If the edge of a cutting polygon is in exactly the same position as the edge of the part to be cut, it can be unclear whether the edge should be cut away. See online help for more detailed information on using this command. Part cut

This command creates an anti-material cutting part. Tekla Structures does not delete the original cutting part. An anti-material part only cuts the selected main part. Tekla Structures displays the anti-material part using dot-dash lines. You can cut parts that already have cuts. For example, you can cut anti-material parts to create more sophisticated cut shapes.

122





Cut symbol Hidden lines Hidden lines (cutting part deleted)

Do not create cuts with the same planes or vertices. This makes it unclear what should be cut away.

See online help for more detailed information on using this command.

Polygon shape You can modify the shape of a polygonal part using the Detailing > Modify Polygon Shape command. You can use this command on the following parts:

www.cadfamily.com

• •

polybeam

•

strip footing

•

concrete polybeam

•

5.1 Examining the model Introduction

This section describes a variety of tools you can use to view your model by changing its position and orientation within the view window. It also covers flying through the model.

Zoom commands The zoom tools allow you to focus in on a particular area, or pull out for a wider view. You can use a mouse, or keystrokes, or a combination of both. You use the majority of these tools within an existing view. However, a zoom window must be open to use the Magnifier and Pan tools. The Zoom commands are:

www.cadfamily.com



TEKLA STRUCTURES 14.0 Settings and Tools

Zoom command

Icon

Description

Zoom in

Works within the existing view.

Zoom out

Works within the existing view.

Zoom original

Restores the original level of zoom. Works within the existing view.

Zoom previous

Restores the previous zoom. Use this to switch between the last two zooms. Works within the existing view.

Create zoom window

Creates a new zoom window from an existing view. You can only create zoom windows from wire frame views. The zoom window contains two additional commands, Magnifier and Pan.

Active window

The commands below Active window automatically zoom the active window. So you do not need an extra click to complete the command.

Magnifier

See Magnifier (p. 127). Only available in a zoom window.

Pan

See Pan (p. 129). Only available in a zoom window.

Zooming with mouse Use the Zoom in tool to focus in on a specific area of the model. The Zoom out tool pulls out for a wider view. Both work within an existing view window. How you use the zoom tools depends on the pointing device you are using: a 3-button mouse, or a wheel mouse.

3-button mouse To use zoom with a 3-button mouse: 1. 2.

Open the model. Click the zoom in or zoom out icon on the Zoom toolbar.

3.

Click the area of the model that you want to examine.

4.

Continue to click to zoom further in or out.

Wheel mouse Tekla Structures has two zoom modes you can use with a wheel mouse:

• •

In mouse-wheel mode, scroll the wheel to zoom in and out. In scroll mode, you can also hold down the wheel when scrolling.

To use zoom with a wheel mouse: 1. 2.

126

Open the model. Click the zoom in or zoom out icon on the Zoom toolbar.

Using keystrokes To zoom using keystrokes: 1. 2.

Open the model. With the mouse cursor over the model, press Page Up to zoom in, Page Down to zoom out.

Zoom settings Centered zooms

To keep the center point of the view in the middle of the view window, regardless of the position of the pointer, check Centered zooms on the Setup menu. If Centered zooms is not checked, the pointer does not move.

Zoom ratio

The following variables control how much you zoom in or out with each click.

3-button mouse

Use the variable XS_ZOOM_STEP_RATIO to control the zoom ratio when using a 3-button mouse. The default value is 0.25. Increase this value to zoom in or out more with each click.

Wheel mouse

See also Wheel mouse (p. 126). To set the zoom ratio when scrolling (not holding down) the wheel, use the variable XS_ZOOM_STEP_RATIO_IN_MOUSEWHEEL_MODE. To set the zoom ratio when scrolling and holding down the wheel, use the variable XS_ZOOM_STEP_RATION_IN_SCROLL_MODE.

Creating a zoom window Opening a zoom window gives you access to additional tools, the Magnifier (p. 127) and Pan (p. 129). These appear on the toolbar within the zoom window.

You can only create zoom windows from wire frame views.

To create a zoom window: 1. 2.

In the View Properties dialog box, click Wire frame in the View type list box. Click Modify.

3.

Click View > Zoom > Create Zoom Window.

4.

Click a starting corner for the zoom window, then drag the pointer to size the window. Release the mouse button to create the window.

5.

Move the zoom window to a convenient location on the screen.

6.

Resize the zoom window by dragging the window boundaries.

Magnifier The Magnifier is useful when you need to keep a general view of the model open, and examine particular areas in detail, at the same time. To use theMagnifier, you must have both a general view window containing the model and a zoom window open. See Creating a zoom window (p. 127).

www.cadfamily.com




127

Click the Magnifier icon in the zoom window. As you move the pointer in the general view, the zoom window displays the area around the pointer in detail, as shown in the example below. Change the level of magnification by zooming in and out in the zoom window.

Moving the model in the view window In Tekla Structures you can move, pan, rotate or fly through a model, in the view window.

Move The Move commands move the viewpoint (or camera) rather than the model itself. Use the up, down, left and right arrows on the keyboard to move the viewpoint. You can also click View > Move to use the move commands. Center by cursor

128

To center the model on a particular point, click View > Move > Center by Cursor, then click anywhere in the view to center the view on that point.





Pan The Pan command moves the model itself. Activate dynamic panning using the P key on your keyboard, or click View > Move > Pan. The pointer will change to a hand. Click and drag the mouse to move the model anywhere within the view window. You can also pan while using the Fly command. To do this, activate the Fly command, and use the middle mouse button to pan when needed. Flying through the model (p. 130)

Clash check When you have completed your model, run the Clash check to find parts, bolts, or reference model objects that collide.

Clashes of objects that are only touching one another are not included in the clash check log.

Steps

1. 2.

Select the objects you want to check. Click Tools > Clash check.

3.

The clash check progress is displayed in the status bar. You can continue working during the clash check. If there are no colliding parts, Tekla Structures displays the message No collisions detected on the status bar.

If parts, bolts, or reference model objects collide, Tekla Structures highlights them in yellow and displays the clash check log in the List dialog box. If you start clash checking while another clash check is still running, you can choose whether to continue checking, restart the operation and check the currently selected parts, or stop checking. 4.

Set bolt clearance

134

To quickly locate and view colliding parts in the model, select the line containing the ID numbers of colliding parts from the list. Tekla Structures highlights the parts in the model. Hold down the F key while you do this to have Tekla Structures fit the work area.

To define bolt clearance for clash checking, click Tools > Options > Options... > Clash check. Enter the values in the Bolt clash check settings dialog box.





d is the larger value of the bolt head or nut diameters Clash check clearence The clash checking clearance area is grey. Select the checkbox in front of the field if you want to use the clearance value. If you clear the checkboxes, the clearance will be zero.The clearance in front of the bolt head is equal to the bolt length. If you do not enter values for clearances, Tekla Structures uses the default value of 1.00. You need to save the clearance values to use them in future sessions. Click Tools > Defaults > Save Defaults.

If Tekla Structures cannot find the bolt head or nut diameter in the bolt catalog, it uses the shank diameter. Reference models

The following reference model file types are supported in clash checking:

• •

IFC

•

DGN

DWG

If you are working on a large model, running the clash check may sometimes be slow. In that case you can use the old clash checking functionality, which does not recognize clashes with reference models. For more information, see XS_USE_NEW_CLASH_CHECK and XS_CLASH_CHECK_BETWEEN_REFERENCES.

Compare Use this tool to compare two assemblies or parts.

www.cadfamily.com

5.3 Copying and moving objects Use the Copy and Move tools to copy and move objects linearly, with rotation, or with mirroring. Copy creates a new object, leaving the existing object in its original position. Move relocates the existing object. Copy Special and Move Special provide additional options for copying and

moving objects. You can also move the view plane of a selected view. When you move a view, Tekla Structures only uses the vector perpendicular to the view plane. Limitations

Tekla Structures does not mirror connection properties, so Mirror does not fully mirror objects if they include connections that contain, for example, asymmetrically positioned parts.

Duplicate objects

When you copy or move objects, Tekla Structures checks for duplicate objects in the location where you are about to copy or move the objects to. Tekla Structures also checks for duplicates if you create new parts in the same location with an existing part.

Tekla Structures considers two objects duplicates if they have the same orientation and the same size of bounding box.

Use the variable XS_DUPLICATE_CHECK_LIMIT_FOR_COPY_AND_MOVE to define the maximum number of objects that are checked for duplicates while copying or moving objects. If duplicates are found, you can choose whether to keep or delete the duplicate objects.

This functionality does not apply to objects that you copy by using a modeling tool, such as the Array of Objects (29) component.

Copy To create copies of selected object(s):

138

1. 2.

Select the objects to copy. Click the Copy icon, or click Edit > Copy.

•

object representation settings

view depth

Work area and view depth are like two virtual boxes. Objects which have their center line partially or totally inside both boxes are visible. Newly created objects are visible also outside the view depth but never outside the work area. Redrawing a view only shows the objects inside the view depth (for redrawing, see also Refreshing the screen display (p. 60). Object visibility

To define which objects are visible and how they are displayed in a view: 1. 2.

Double-click the view. In the View properties dialog box, click Display.... The Display dialog box appears.

3.

Set the visibility and representation for different object types and for components.

Creating object groups To create a new object group: 1. 2.

Click View > Representation > Object Representation... to open the dialog box. Select Create new group... in the list box in the Object group column, and the Object group - representation dialog box opens.

3.

Enter the name of the object group and click Save as.

• 4.

• •

The object group you create is saved in the model’s attributes folder. See Object group files (p. 147). Click Add row to define a rule. Rule is based on selected Category, Property, Condition, and Value. See Object group rules (p. 148) for more information on creating rules.

5.

Use the Add row button to add rows for more rules. Use the Delete row and Delete all buttons when needed.

6.

When the set of rules is ready, click Save.

7.

Click Close.

8.

The new object group is shown in the Object representation dialog box.

Object group files Filenames

Tekla Structures saves object group representation files with filename extension *.PObjGrp. Tekla Structures has three different object group types: view filter, selection filter, and object representation. All these use different object group files, so you cannot, for example, use selection filter object groups in the view filter.

Filename extension

File location

Object group filename extensions depend on the purpose the group was created for:

Filename exten-sion

Created in dialog box

*.PObjGrp

Object group - representation

*.VObjGrp

Object group - view filter

*.SObjGrp

Object group - select filter

Object groups are saved in the current model’s attributes folder.

•

To make an object group available in another model, copy its file to the attributes folder of the destination model.

•

To make an object group available in all models, copy its file to the system folder.

You must restart Tekla Structures to apply the changes. Tekla Structures searches for the object group files in the default order. For more information, see Folder search order in the online help.

www.cadfamily.com




147

A consistent naming policy for created object groups is important, as handling the object group files is done manually in the model, project, firm, and system folders.

Deleting an object group

To delete an object group, delete the object group representation file located in the attributes folder.

5.5 Filter Introduction

The Filter option is useful when you want to perform an operation on several objects or properties at the same time. This section describes the Selection and View filters.

• •

Use the Selection Filter to avoid making errors when selecting objects. Use the View Filter to define which objects appear in each view. This is particularly useful for complicated models containing a large number of objects.

The view and selection filters are based on the object group functionality. Fore more information, see Object groups (p. 146).

View filter Use the View filter to define which objects are displayed in a view, according to object properties. Work area, view depth, view setup, and the object representation settings also affect whether an object is visible. See Displaying and hiding objects (p. 143). To display the View filter dialog box: 1.

Double-click the view to open the View properties dialog box, or click View > View Properties....

2.

152

Click the Object group... button.





Selection filter Use the Selection Filter to define which objects can be selected. Tekla Structures also contains several switches that control whether you can select an object (see Controlling the selection (p. 38)).

To use the Selection Filter on an object, the object must be visible in the relevant view. See View filter (p. 152) for more information.

Selection filter dialog box To display the Object Group - Selection Filter dialog box:

• •

www.cadfamily.com

Click the Selection Filter icon

, or

click Edit > Selection Filter....




153

Use object properties to define whether or not an object can be selected. To use the Selection Filter dialog box that was available in previous versions, set the variable XS_USE_OLD_FILTERING to TRUE.

Using the variable XS_USE_OLD_FILTERING affects only the appearance of the dialog box. Internally Tekla Structures uses the new filters in all filtering.

See also

XS_USE_OLD_FILTERING

Standard selection filters Tekla Structures contains several standard selection filters. The selection filter list box on the Selecting toolbar lists both standard and user-defined filters.

154





To apply a filter, select one from the list. Standard filters always appear first on the list.

Converting old selection filters The selection filter list box is divided into two parts:

• •

www.cadfamily.com

New selection filters (file extension .SObjGrp), which you can use in selection filtering Old filters (file extension .msf)




155

When you select an old filter, Tekla Structures automatically converts it to a new filter and saves the new filter. The old filter is then removed from the list box.

Defining your own filters To define your own filters: 1.

, or click Edit > Selection Filter... to open the Object Click the Selection Filter icon Group - Selection Filter dialog box.

2.

Find a filter which has close to the same settings as you need.

3.

Modify the settings, then enter a new name in the Save as field.

4.

Click Save as, then OK to exit. You can now choose the new filter from the dropdown list.

To have the filters you define appear at the top of the list, right after the standard filter, use capital letters in the filter name.

Examples

The Selection Filter is very useful when using the drawing wizard to automatically create drawings. For example, if you only want to produce drawings of the beams in the model, use the Selection Filter to select them. Use the Selection Filter to select the parts you want to carry loads.

156





Filtering techniques Filter by multiple properties

You can define filters containing several properties. You can also have multiple filtering values for each property. If you use multiple values, separate the strings with blank spaces (for example, 12 5). If a value consists of multiple strings, enclose that particular value in quotation marks (for example, "custom panel"). By using conditions, parentheses, and the And/Or option you can create filters that can be as complex as needed.

When you create rules between objects that represent different categories, use the And option when possible to avoid potential problems with more complex rules.

Set filtering on

To set filtering on for a particular property, select the corresponding checkbox. The checkboxes define which rows of the filter are enabled and effective. In the following example, only the second row affects filtering:

To use complement filtering (in other words, defining which parts not to select), select Does

Complement filtering

not equal in the Condition column.

Template properties

You can select objects according to template properties. To do this, select Template in the Category column, and then select the desired property in the Property column.

www.cadfamily.com




157

In the Object Group - Selection Filter dialog box, use the following units for template properties, even when using the US Imperial environment:

• •

mm for lengths

•

kg for weights

•

degree for angles

mm2 for areas

To check which units Tekla Structures uses for certain template properties, use the Select from model... option in the Value column. Assembly types

If the category you have selected is Assembly, the property you have selected is Assembly type, and you use the option Select from model... in the Value column, Tekla Structures returns the value as a number. The number indicates the type of assembly in question. The following table lists the numbers and the corresponding assembly types:

Filtering examples Beams and columns

To create a selection filter for beams and columns: 1. 2.

Click Add row twice to add two new rows. Fill in the part names, BEAM and COLUMN.

To select the value directly from the model, click Select from model... and pick an object.

3.

Select the Or option. The filter is now looking for an object that has the Name BEAM or COLUMN.

The same result is accomplished if you write BEAM COLUMN in the Value column in the first row. If you use multiple values, you must separate the strings with blank spaces.

4.

158

Enter the filter’s name next to the Save as button, and click Save as.





To create a selection filter for all parts in phases 1 and 2:

Phases

Complement filter

www.cadfamily.com

1. 2.

Click Add row. Fill in the part phases, 1 and 2. Separate the strings with a blank space.

3.


If you only want to select certain parts, use complement filter to filter out the remaining parts.




159

Select switches also affect the selection of objects. See Controlling the selection (p. 38).

To create a filter that selects all parts except for those with the profile BL200*20: 1. 2.

Click Add row. Fill in the profile, BL200*20.

3.

In the Condition column, select Does not equal.

4.


Using wildcards You can use wildcards to shorten filter strings. A wildcard is a symbol that stands for one or more characters. Tekla Structures uses the following wildcards:

Wildcard

Description

Example

* (asterisk)

Matches any number or characters

HE* matches all parts with a profile name that begins with the characters "HE". You can also this symbol at the beginning of a word: *BRAC*.

160





Wildcard

Description

Example

? (question mark)

Matches a single character

HE?400 matches parts with profile names such as HEA400, HEB400, and HEC400

[ ] (square brackets)

Matches whatever is enclosed in the brackets

L[78]X4X1/2 matches parts with the profile names L7X4X1/2 and L8X4X1/2

The characters * and ? can also be used in object names. If the object name you want to filter contains * or ?, enclose * or ? in square brackets. E.g., to find the profile P100*10, enter P100[*]10 in the filter field.

Filter in dialog boxes The Filter also appears in many dialog boxes. In a Filter field you can enter characters from the name of the object you are looking for, and then click the Filter button to find the matching names. See also Using wildcards (p. 160).

5.6 Settings This section explains how to modify various settings in Tekla Structures.

In this section

Units and decimals To configure how units and decimals are input, output, stored and displayed, click Tools > Options > Options... > Units and decimals. Update

When you click OK in the Units and decimals dialog box, Tekla Structures updates the format of units and decimals in all open dialog boxes.

Input and output data

Different types of data are separated onto three tabs in the Units and decimals dialog box. Input data appears on the Modeling and Catalogs tabs. Output data appears on the Analysis results tab (output data only relates to structural analysis).

www.cadfamily.com




161

Modeling functions

The settings on the Modeling tab affect the data you use when using modeling commands, such as copy, move, create grid, create point, part location, and dimensions.

Catalogs

Settings on the Catalogs tab affect the data stored in the profile and material catalogs.

No effect

Settings in the Units and Decimals dialog box have no effect on drawings, reports, or the Inquire and Measure tools.

The number of decimals affects input and storage accuracy. Always use a sufficient number of decimals.

The decimal point symbol is always a period (.). It cannot be changed. Exponent notation

You can use positive exponent notation, but not negative exponent notation.

Imperial units You can input length in imperial units in the following ways:

Fractional notation

162

• •

Inches in decimals (e.g. 300.5")

•

Fractional notation (e.g. 60'-6")

Feet in decimals (e.g. 62.7')

In fractional notation, all input is shown in feet (') and inches ("). If you are using imperial units and want to use fractions, you must use fractional notation.





Mouse and pointer settings You can configure your mouse and pointer settings to suit the way you work using:

• •

Pan (p. 163)

•

Xmouse (p. 163)

•

Xsnap (p. 164)

•

Rollover highlight (p. 164)

Drag and drop (p. 163)

Pan Pan toggles the function of the middle mouse button between panning and scrolling. To switch between scrolling and panning, click Tools > Options > Middle Button Pan, or press Shift+M.

Scrolling moves the “viewer”, and panning moves the model. Hold down the middle button and drag the pointer away from the origin of the object. To scroll faster, drag the pointer farther from the origin mark; drag closer to slow down. You can use Scroll and Pan when other commands are active.

Drag and drop With Drag and drop active, you can use drag and drop to move or copy parts. You can also modify polygon shape using drag and drop. You cannot drag and drop components, component parts, bolts, or welds. To toggle Drag and drop on and off, use the keystroke D, or Tools > Options > Drag and Drop. It remains active until you switch it off.

Activate

Tekla Structures remembers this setting between sessions by user name.

To avoid accidentally dragging and dropping parts, de-activate drag and drop when you are not using it.

With both Drag and Drop and Smart Select active, you can drag and drop handles without selecting them first.

Smart Select

To toggle SmartSelect on and off, use the keystroke S, or select Tools> Options > Smart Select. It remains active until you switch it off. Tekla Structures remembers this setting by session and user name.

Xmouse With Xmouse active, moving the pointer over a view activates the view. Without Xmouse you have to click on a view to activate it. To toggle Xmouse on or off, click Tools > Options > Xmouse. A checkmark appears next to the menu option if Xmouse is already active. Using Xmouse

www.cadfamily.com

Xmouse is useful when you are using two views that partly overlap. See the following examples:

•

If you want to pick beam positions from two overlapping views, with Xmouse active you simply move the pointer over the view to activate it.

•

With Xmouse active, you can also use the Page Up, Page Down and arrow keys in overlapping views, without having to click a view to activate it first. See Moving the model in the view window (p. 128).




163

Xsnap Xsnap helps you to snap to the correct points by giving you visual cues. As you move the pointer

over an object, Tekla Structures automatically highlights the points it suggests you snap to. Activate

To toggle Xsnap on and off, use the keystroke T or Tools > Options > Xsnap. It will stay active until you turn it off. Tekla Structures remembers this setting by session and user name.

Snap switches

Use snap switches to control the kind of items to which the cursor reacts. See Specifying points (p. 33).

Rollover highlight As you move the mouse pointer over objects in rendered model views, Tekla Structures highlights the objects in yellow, so that you can easily see which objects you can select.

Activate

To turn Rollover highlight on and off, press H or click Tools > Options > Rollover highlight.

Phases In Tekla Structures, you can use phases to break up a model into different sections. Phases are often used to indicate erection sequences. You can create reports and views, hide objects, and copy objects from other models, according to their phase number. Example

For example, you have a large project on which several users will work simultaneously in singleuser mode. First create a basic model which includes, for example, the columns. This is phase 1. You then copy this basic model to all users. Each user then works on a separate part of the building. As each part of the model is completed, you can copy it back to the basic model as a separate phase (phase 2, 3, etc.).

Working with phases

164

To work with phases, click Tools > Phase Manager.... The Phase manager dialog box appears.





The following table explains how to use the buttons in the Phases dialog box.

Additional properties

5.7 Numbering This section explains how to change numbering settings and apply numbering in Tekla Structures.

Numbering settings To open the Numbering Setup dialog box, click Drawings & Reports > Numbering > Numbering Settings...:

168





You can use various numbering options:

www.cadfamily.com




169

Option

Action if checked

Renumber all

Tekla Structures renumbers all parts. All information on previous numbers is lost.

Reuse old numbers

Tekla Structures reuses numbers assigned to parts that have subsequently been deleted. These numbers may be used to number new or modified parts.

Check for standard parts

If a separate standard part model has been set up, Tekla Structures compares the parts in the current model to those in the standard part model. If the part to be numbered is identical to a part in the standard model, Tekla Structures assigns it the number of the part in the standard model.

New parts

Modified parts

Options when numbering new parts:

Option

Action

Compare to old

A new part gets the same number as a previously numbered similar part.

Take new number

A new part gets a number not used in previous numbering, even if a similar numbered part already exists.

Options when numbering modified parts:

Option

Action

Compare to old

Same as for new parts (above)

Take new number

Same as for new parts (above)

Keep number if possible

Modified part maintains its previous number if possible.

Always carry out full numbering on the model after you have changed numbering settings. See Number All Partsthe online help.

Family numbering With family numbering you can group objects within the same numbering series into different “families”. When you use family numbering, the cast unit position numbers consist of family number and qualifier. For example:

170





Family number Qualifier

See also

•

The family number is the same for assemblies and cast units which match the criteria you define in the Numbering setup dialog box.

•

Assemblies or cast units which have the same family number but different exact geometry or materials get unique qualifier numbers.

Assigning family numbers for series (p. 171) Assigning family numbers for parts (p. 173)

Assigning family numbers for series On the Family numbering tab, you can assign family numbers for series. For example, the following two beams both have the numbering series prefix B:

Assembly position: B/1 Assembly position: B/2 The beams are otherwise similar, but the connections used are different. To assign family numbering for the series: Usage

1. 2.

www.cadfamily.com

Click Drawings & Reports > Numbering > Numbering Settings... to open the Numbering Setup dialog box. On the Family numbering tab, click Add series to open the Add series dialog box, which lists all the assembly and cast unit numbering series in the model.




171

Select the numbering series B/1 and click Add. The numbering series appears in the family numbering list.

4.

Use the Compare section of the dialog box to define what to compare for the numbering series. Define the compare criteria for each numbering series separately. a Select at least one checkbox, but not all of them. b If you select all checkboxes, the family number will be the same as the normal assembly position, and the qualifier number will be 1 for all. If you do not select any checkboxes, only one family number per series is assigned.

5. 6. 7.

Click Apply or OK. Update the numbering in the model. Tekla Structures assigns the beams family numbering.

Tekla Structures considers beams different according to the compare criteria you defined, and they get different family numbers:

Result

172

3.





Assembly position: B/1-1 Assembly position: B/2-1

Assigning family numbers for parts To assign a family number and/or family qualifier for parts: Usage

1. 2. 3. 4.

Select the objects whose family numbers you want to change. Click Drawings & Reports > Numbering > Change Number > Family Number.... In the Assign Family Number dialog box, enter the desired values in the Family number and Family qualifier fields. Click Assign.

Assembly position numbers You can sort the order in which assemblies are given their position numbers. To do this, use the options in the Numbering Setup dialog box:

You can sort the position numbers in ascending or descending order.

www.cadfamily.com




173

The sort order can be based on the following criteria:

• •

The x, y or z coordinates of the main part of the assembly.

•

The user-defined attribute of the main part.

The user-defined attribute of an assembly.

If your sorting is based on user-defined attributes, Tekla Structures displays a list box that includes all the available user-defined attributes.

When sorting by x, y or z coordinates, the sorting is based on the center of gravity of the reference axis.

Sorting by user-defined attributes or by location does not affect the part position.

If you add new parts, already numbered objects are not renumbered to suit the sorting order by, for example, the x coordinate. In this case you should renumber the parts.

Numbering Settings...

Numbering examples Part numbers

This example explains how different numbering settings result in different part numbers when you modify a part. 1. 2.

Create three identical beams with the numbering series prefix P and start number 1. Number the model. All the beams have the part position number P1.

3.

Modify one of the beams.

4.

Number the model. You should now have two beams P1 and one P2.

5.

Change beam P2 to be identical to the others.

6.

Number the model.

Tekla Structures assigns different part position numbers to this part, according to which numbering settings you used, as follows:

Project phases

174

• •

Compare to old: P1

•

Take new number: P3

Keep number if possible: P2

When you start modeling a project, the required numbering settings may be totally different from what they are after the project has been issued for the first time and you start revising the model.





To control numbering settings on different phases of the project, create pre-defined numbering settings for the different phases of the project. Save the settings with the Save as button. For example:

•

Phase 1 - Stick modeling Doing only modeling before any drawings are released. At this stage you may even want to select Renumber all, or at least Re-use old numbers.

•

Phase 2 - Drawing issue When the first set of drawings is issued, but modeling continues, you may want to minimize the effects to already issued drawings. You can do this for example by selecting Keep number if possible in the Modified list box.

•

Phase 3 - Revisions At some point the project is more or less finalized, and any changes to the model should be handled in a different way than before. You may want to take a new number for all modified parts, not comparing them to any of the existing parts. To do this, select Take a new number in the Modified list box.

When you reach the next step in a project, you can load pre-defined settings, and then save them as standard. This way the standard settings are always automatically loaded from that point on when someone opens the model.

Applying numbering When you apply numbering, Tekla Structures assigns marks to parts and assemblies. Numbering is carried out according to the settings in the Numbering Setup dialog box (see Numbering settings (p. 168)). Pop-marking

Pop-marking for NC files also affects numbering. When pop-marking is activepop-marks, Tekla Structures will assign different numbers to identical parts if they have different pop marks.

Example

Two main parts in different assemblies are identical, apart from a difference in the position of the plates welded to them. In this case, Tekla Structures assigns them different numbers.

Interrupt numbering

You can safely interrupt numbering before it is complete by clicking Cancel in the dialog box Tekla Structures displays while it is running. If you interrupt numbering, parts and assemblies retain their original numbers.

5.8 Tools Introduction

This section describes various tools in Tekla Structures that help you to model more effectively, as well as tools that you can use to check a model and prepare it for fabrication.

Snapping Tekla Structures includes many tools you can use alone or together with other tools to snap to specific locations. These tools are:

• •

Snap switches (p. 33)

•

Orthogonal snapping (p. 178)

•

Tracking (p. 179)

•

Temporary reference points (p. 179)

Numeric snapping (p. 177)

See also Snapping examples (p. 179).

Numeric snapping Use the Enter a numeric location toolbar to key in position coordinates you want to snap to.

www.cadfamily.com




177

To display the toolbar, initiate a command that requires you to pick positions, and then do one of the following:

• •

Start entering the coordinates using the keyboard. Click Tools > Enter a Numeric Location and select an option. To access additional options, click Tools > Options > Shortcuts > Enter a Numeric Location.

The following table explains the types of information you can enter.

You can enter

Description/Example

Special character

Cartesian coordinates

The x, y, and z coordinates of a position separated by commas, e.g. 100,-50,-200.

, (comma)

Polar coordinates

A distance, an angle on the xy plane, and an angle from the xy plane separated by angle brackets, e.g. 1000<90<45.

<

Angles increase in the counterclockwise direction. Absolute coordinates

The coordinates based on the origin of the work plane.

Set with the variable XS_KEYIN_ABSO LUTE_PREFIX

Relative coordinates

The coordinates relative to the last position picked, e.g. @1000,500 or @500<30.

Set with the variable XS_KEYIN_RELA TIVE_PREFIX

One value

A distance to an indicated direction.

Two coordinates

If you omit the last coordinate (z) or angle, Tekla Structures assumes that the value is 0.

Three coordinates

In drawings, Tekla Structures ignores the third coordinate. After you enter the coordinates, press Enter or click OK to snap to the position. Snapping mode

Tekla Structures has two snapping modes, relative and absolute. Use the variable XS_KEYIN_DEFAULT_MODE to indicate the default snapping mode.

See also

XS_KEYIN_ABSOLUTE_PREFIX XS_KEYIN_RELATIVE_PREFIX

Orthogonal snapping Use the shortcut O (Tools > Ortho) to snap to positions in orthogonal directions on the work plane (0, 45, 90, 135, 180 degrees, etc.). To control orthogonal snapping, use the variables XS_SEMI_ORTHO_ANGLE and XS_USE_SEMI_ORTHO. For more information, see Appendix C, Variables, in the System Manual.

178





Tracking Tracking means that you follow a line and pick a point at a specified distance along the line. You usually use tracking in combination with other snapping tools, such as snap switches, or orthogonal and numeric snapping. See also Snapping examples (p. 179).

Temporary reference points You can create a temporary reference point to use as a local origin when snapping in models or drawings. 1. 2.

Initiate a command that requires you to pick positions. Hold down the Ctrl key and pick a position. A green cross indicates that this position is now a temporary reference point.

3.

Use this temporary reference point with snap tools to define directions and distances.

See also Snapping examples (p. 179).

Snapping examples When you have snap switches on and you use a command that requires you to pick positions, the mouse pointer locks onto a snap point. Tekla Structures displays a magenta line between the last point picked and the snap point.

You can track along the line towards a snap point, and use the Enter a numeric location toolbar to specify the distance from the last point picked. You can also track along an orthogonal direction. See Orthogonal snapping (p. 178). In the illustration below, we snapped to a grid line midpoint and tracked along the tentative line for 1000 units.

www.cadfamily.com




179

You can also track beyond the snap point, for example, 4000 units from the last point picked.

Track in the opposite direction by entering a negative value, for example, -1000.

Reference points

180

In this example, we create a beam using a grid line midpoint as a temporary reference point and tracking along an orthogonal direction (shown as green dashed line) for 500 units. Click OK, and Tekla Structures creates the beam along the magenta line.





You can lock the x, y, and x coordinates on a line. This is useful when you need to determine a point to pick and the needed point does not exist on the line.

Locking coordinates

To lock the x coordinate, for example, press x on the keyboard. To unlock the coordinate, press x again.

Sequencer Use Sequencer to name sequences and assign incremental numbers to parts. There are many uses for the Sequencer, including defining erection sequences. You can define several sequences for different purposes. You can include the same parts in several sequences at the same time. The Sequencer works by assigning user-defined attributes to parts. So you can use the Sequencer to create user-defined attributes when you only need to use numeric values. With Sequencer you can also assign numeric values to existing user-defined attributes.

Creating a report To include the sequence number in reports, enter the sequence name in the text field. You can also use the sequence number in a report by entering the sequence name in the table part row.

To create a list showing all the parts belonging to a sequence, use the following rule in a row or intermediate row in the Template Editor: if(curr("SEQUENCENAME") != 0) then do()

Checking the sequence value You can check the name and number of a sequence using the Inquire object command. To do this, the sequence name must appear as a user-defined attribute in the objects.inp file. For more information, see Adding properties in the System Manual.

Using Sequencer Click Tools > Sequencer to open a dialog box displaying existing sequences. You can enter the following information:

Introduction

This chapter introduces the advanced modeling techniques available in Tekla Structures. It also includes some modeling tips.

Contents

This section includes the following topics: Sketching and using cross sections (p. 195) Parametric modeling (p. 212) Warping, cambering, and shortening parts (p. 214) Modeling tips (p. 217)

6.1 Sketching and using cross sections Tekla Structures includes a cross section sketch editor, which you can use to create your own profile cross sections. Sketched cross sections are parametric, so you can change their dimensions each time you use them in a model. The Sketching toolbar is embedded in the Cross section sketch editor. It contains the tools you need to define and save cross sections:

This section explains how to create and edit your own cross sections, and use them in models. It contains the following topics:

Description

Sketch polyline

Sketch lines.

Sketch arc

Sketch an arc.

Sketch circle

Sketch a circle.

Ensure that you create a closed shape:

•

Try to start sketching at a point that is easy to pick, such as a gridline intersection.

•

If necessary, use the Coincident constraint tool to close it.

Next you need to add constraints and dimensions, and save your sketch. See:

196

• •

Using constraints to lock cross section shape (p. 197)

•




Advanced Modeling www.cadfamily.com EMail:[email protected]


Tekla Structures will not save a cross section that does not have dimensions.

Using constraints to lock cross section shape After you have sketched the outline of a cross section, use the constraint tools to refine your sketch and lock the shape, for example, to straighten lines, create 90° angles, force lines to meet, and close the shape. The Sketching toolbar includes the following tools to create constraints:

Command

Icon

Description

Sketch radial dimension

Creates a radial constraint for an arc or circle.

Sketch angle dimension

Creates an angle constraint for an arc or circle.

Parallel constraint

Force a line to be parallel to another line.

Perpendicular constraint

Force a line to be perpendicular to another line.

Coincident constraint

Force two lines to meet (extends or shortens one or both lines.) Useful when you need to close a shape. Tekla Structures automatically creates coincident constraints:

Fixed constraint

www.cadfamily.com

• •

Where 2 lines meet

•

Between the start of the first line segment and the end of the last line segment in a shape, if they are within a certain distance of each other.

Between line segments when you draw them with the Sketch polyline tool.

Locks the position and angle of a line, so that other constraints do not affect it.




197

Command

Icon

Horizontal constraint

Description Force a line in the sketch to be parallel to the local x axis. Use with other constraints to straighten the entire profile. Tekla Structures automatically creates horizontal constraints for horizontal lines, and lines that are almost horizontal.

Vertical constraint

Force a line in the sketch to be parallel to the local y axis. Use with other constraints to straighten the entire profile. Tekla Structures automatically creates vertical constraints for vertical lines, and lines that are almost vertical.

See the online help for a step-by-step example on using these tools. See also

Sketching cross sections (p. 196) You can choose to create chamfers in your cross section. Then you need to add dimensions, and save your sketch. See:

• •

Defining chamfers (p. 199)

•



Tekla Structures will not save a cross section that does not have dimensions.

Deleting constraints To delete a constraint:

Right-click and select Delete from the pop-up menu:




Defining chamfers When you use the Create polyline tool to sketch a profile, Tekla Structures automatically creates coincident constraints between the line segments and displays a chamfer symbol where line segments meet

.

To change the shape or dimensions of a chamfer: 1. 2.

For each chamfer you want to change, double-click the chamfer symbol in the sketch. Tekla Structures opens the Chamfer properties dialog box. Change the shape and dimensions of the chamfer.

Select chamfer shape Enter chamfer dimensions 3.

Click Modify to modify the chamfer.

4.

Click OK to close the Chamfer properties dialog box.

5.

Click the Save sketch icon to save the changes.

Adding dimensions to cross sections After you have sketched a parametric cross section, use the dimension constraint tools on the Sketching tool bar to create dimensions for it. You can use these dimensions to define the size of the profile cross section when you use it in a model. Tekla Structures also adds the dimensions you create to the list of variables that you can use in calculations. See Using variables to define cross section properties (p. 201).

Tekla Structures will not save a parametric cross section that does not have dimension constraints.

The Sketching toolbar includes the following tools to create dimensions.

www.cadfamily.com

Command

Icon

Description

Sketch free distance

Creates a dimension between any two points.

Sketch horizontal distance

Creates a horizontal dimension.

Sketch vertical distance

Creates a vertical dimension.

Using planes to position parts and connections By default, Tekla Structures determines the position of parts using the outline of the part or connection, together with the options you select in the Positions section of the Position tab in the part properties dialog box. For example, the Middle option positions a part based on the geometric center of the part profile. See also Part location (p. 82). Part positioning planes

You can have Tekla Structures use part positioning planes instead of the part profile outline to calculate the On plane and At Depth part position options. For example, you can create part positioning planes that define the Middle option of an asymmetrical profile:

Part positioning planes Middle option based on the intersection of part positioning planes, not part outline The part positioning planes appear as blue lines in the Cross section sketch editor view. Connection positioning planes

Tekla Structures uses connection positioning planes to define the position of components relative to parts. Connection positioning planes appear as green lines in the Cross section sketch editor view. The following image shows the default connection positioning planes and locations where you can place details when the part is a double tee slab created as sketched cross section.

200




The green line illustrates the default connection positioning planes When creating a detail to the slab, select the detail location using the following checkboxes on the General tab in the component dialog box.

If you want to place details as in the image below, you need to move connection positioning planes.

Show or hide part positioning planes

Allows you to move part positioning planes. When you use the profile in a model, the On plane and At depth part position options are based on these planes, not the outline of the profile.

Show or hide connection positioning planes

Allows you to move connection positioning planes.

Using variables to define cross section properties You can define variables to define the properties of a sketched cross section. Variables can define fixed properties, or they can include formulas, so that Tekla Structures calculates the property value each time you use the profile in a model. For example, you can create a variable that calculates a dimension:

Display variables

More information View, add or change variables in parametric model objects, including sketched cross sections. Works the same way as Display variables in the Custom component editor.

Display sketch browser

Opens the sketch browser, which shows the elements in a sketched parametric cross section. Works in the same way as Custom component browser.

Example: Symmetric C This example shows how to use the Variables dialog box and Sketch Browser. We create a symmetric C-shaped cross section with b1 = b2 and h2 = h3. When you use the profile in the model, you can change the following dimensions:

202

• •

Thickness (P1)

•

Height (h2)

•

Width (b1)

Total height (h1)




First, create the cross section and distances: 1.

Click Modeling > Profiles > Define Cross Section in Sketch Editor... to open the sketch editor. Use the Sketch polyline command to create a C-shaped cross section.

2. 3.

Use the Sketch horizontal distance and Sketch vertical distance commands to create all distances. All the created distances are automatically displayed in the Variables dialog box.

• •

www.cadfamily.com

To change the distance value, click the Formula cell and enter a new value. To make the profile symmetric, type =h2 in the Formula cell of distance h3 and =b1 of distance b2.

Creating a picture of a cross section Library profiles include pictures which illustrate the shape and dimensions of each profile. To add pictures of sketched parametric cross sections: 1. 2.

Using screenshot

Using any image editor, e.g. Paint, create an image that shows the shape and dimensions of the profile. Save the image in the folder ..\TeklaStructures\*version*\nt\bitmaps, using the cross section name as the filename, with the file extension .bmp. For example, mysketch.bmp.

To use a Tekla Structures screenshot as a picture: 1. 2.

Open the sketch in the cross section sketch editor view. If necessary, click in the sketch to ensure it is the active view. Press F12 on your keyboard to take a screenshot of the sketch, without the borders.

3.

In any file manager, e.g. Microsoft Explorer, rename the screenshot file to have the same name as the sketch, with the extension bmp.

4.

Copy the renamed file to the folder ..\TeklaStructures\*version*\nt\bitmaps.

5.

Tekla Structures displays a picture of the sketch when you browse for profiles.

Naming, saving, and closing cross sections Tekla Structures saves sketched cross sections in the profile catalog in the current model folder.

Tekla Structures will not save a cross section that does not have dimensions. See Adding dimensions to cross sections (p. 199).

The Sketching toolbar includes the following tools to name and save sketched cross sections:

6.3 Parametric modeling Tekla Structures models are parametric, which means that each model object, such as a beam or column, has parameters which define various properties, including its geometry, location and relationship to other parts. You can use these parameters to:

•

Create dependencies, or relationships, between model objects, so the properties of one model object adjust if you change the related model object,

•

Create variables that define the properties of the model object.

We call this technique parametric modeling. This section describes the parametric modeling tools in Tekla Structures. It contains the following topics: Creating dependencies (p. 212) Creating variables (p. 213)

Creating dependencies Tekla Structures includes several tools that you can use to create dependencies, or relationships between model objects. For example, you might create a dependency that offsets a column a fixed distance from a plane on a wall, so that when you move the wall, the column follows.

Warping concrete beams using the Deforming options To warp a concrete beam: 1. 2.

214

Double-click the beam to open the Beam properties dialog box and go to the Deforming tab. In the Start field, enter the angle of the beam at its start point, relative to the part reference line.

3.

In the End field, enter the angle of the beam at its end point, relative to the part reference line. For example, to warp the beam 45 degrees at the end point, enter 0 in the Start angle field and 45 in the End angle field.

4.

Click Modify to warp the beam.

5.

Click OK to close the dialog box.




Warping concrete slabs using end offsets (S62) To warp a concrete slab created using the Slab generation with points (62) component:

1. 2.

Click the Select objects in components on the Selecting toolbar Double-click the slab to open the Beam properties dialog box and go to the Position tab.

3.

In the End offsets section, enter the Start and End offsets of the slab, in the x, y or z direction, relative to the part reference line.

4.

Click Modify to warp the slab.

5.


Using the Move Special tool to warp concrete slabs Use the Move Special command to warp slabs created using the Slab generation with points (S62)component, by picking a single point on the slab. To warp a slab using the Move Special tool: 1.

2.

Click the following icons on the Selecting toolbar:

•

Select objects in components

•

Select points

Use a Crossing window to select the point you want to move.

For example, select the corner point of a slab component to warp that end of the slab

www.cadfamily.com

3.

Right-click and select Move Special > Linear from the pop-up menu.

4.

In the Move - Linear dialog box, enter a value in the appropriate direction field. For example, enter 100 in the dZ field to lift that corner up 100 mm.

5.

Click Move. Tekla Structures moves the point in the direction you selected, which warps the slabs.




215

6.

Right-click and select Interrupt from the pop-up menu to finish.

7.

To see the warping angle of a slab, double-click a slab to open the Beam properties dialog box. Go to the Deforming section of the Position tab.

• •

The Start field shows the warping angle at the start point of the part. The End field shows the warping angle at the end point of the part.

Warping concrete slabs using chamfers To warp concrete parts created using the Concrete slab component on the Concrete toolbar: 1.

Double-click a chamfer on the part to open the Chamfer properties dialog box. Enter values in the following fields:

• •

dz1 to move the upper corner of the chamfer dz2 to move the lower corner of the chamfer

2.

Click Modify to warp the concrete slab.

3.

Click OK to close the Chamfer properties dialog box.

If the chamfers on a concrete slab are invisible, set the variable XS_DRAW_CHAMFERS_HANDLES=CHAMFERS.

Cambering parts Use the cambering option to pre-camber parts, that is to curve long heavy sections that will settle on site and become flat.

Tekla Structures cambers parts in the local z direction. To camber a part:

216

1. 2.

Double-click the part to open the part properties dialog box. Go to the Deforming section of the Position tab.

3.

In the Cambering field, enter the degree of camber.

4.

Click Apply to modify the part.

5.





You can also use the warping and cambering tools together to model parts.

For the cambering to work correctly, you need to bind the objects to a cambered part, and the objects need to be part of an assembly or cast unit.

Limitations

Parts assembled on-site cannot follow a cambered seam. Only embedded parts and custom parts follow the deformations of their parent part.

Shortening parts When drawings of the parts are created, Tekla Structures decreases the true length of the part by this value. This is useful when creating assembly drawings of bracing bars which should always be under tension. To shorten a part: 1. 2.

Double-click the part to open the part properties dialog box. Go to the Deforming tab.

3.

In the Shortening field, enter the degree of shortening.

4.

Click Apply to modify the part.

5.


To have a concrete part lengthened in cast unit drawings, type a negative value in the Shortening field.

Modeling tips This section includes the following topics:

• •

General tips (p. 217)

•

Working with custom components (p. 218)

Detailing (p. 218)

General tips Keep the ’Move Special’ or ’Copy Special’ dialog boxes open if you are going to use them often, for example, when you creating the grids and levels in a new model. To keep a dialog box open, start the command, then right-click and select Interrupt from the pop-up menu. Each time you want to use the command: 1.

www.cadfamily.com

Click in the appropriate dialog box to activate it, then click an object in the model.




217

2.

Enter the values you want to use, then click the Move or Copy button in the dialog box.

3.

Tekla Structures moves or copies the object you selected.

Leaving dialog boxes open uses up system memory and may slow down processes on your computer.

Detailing These detailing tips will help you to detail models more quickly and accurately, and avoid potential problems with templates, drawing, and exports. Always model beams in the same direction. Do not cut the end of a part to shorten it. This can cause shop errors, because cuts do not always affect part length when you export information to NC files. Move the part handles, or use Detailing > Fitting instead. Do not use fitting to lengthen parts. It can cause problems with connections and details. Move the part handles instead. Create a basic part view when you need to see a specific part clearly. This places the part in the center of the view. To further improve the view, use the Hide command to hide adjacent parts.

Working with custom components These tips will help you to efficiently create, save, and share parametric and non-parametric custom components: General

Use library profiles when possible. So you do not have to copy user-defined profiles when you copy the component to other locations. Use short, logical names. Use the description field to describe the component and explain what it does. Store custom components together. It makes them easy to find and export. Consider creating a component model. Use this model to create and test custom components. Provide essential information. If you distribute your component to other users, remember to list the profiles it works with. Remember to copy user-defined profile cross sections with your custom component.

Creating nonparametric components

218

Use the simplest part you can. For example, if all you need is a rectangular shape, use a rectangular plate, not a contour plate. Rectangular plates only have 2 handles, so you only need to create a few bindings or magnetic planes to manipulate them. Contour plates require more because they have 4 chamfers and handles, when you set the variable XS_DRAW_CHAMFERS_HANDLESto CHAMFERS or HANDLES.




Rectangular plate Contour plate Only model parts as accurately as you need. If the only part information required is a part mark on the GA drawing and a quantity on the materials list, create a simple bar or plate. If, later, you need to include it in a detailed view, simply re-model the part more accurately. Creating intelligent (parametric) components

Plan to use magnetic planes to bind objects together. This makes intelligent components simpler, and easier to use, because it reduces the number of dimensions and parameters the user must enter. Model as many parts on the same plane as you can, and then use offsets to position them accurately.

Not using magnetic planes: Pick all 10 handles to bind the parts together Using 3 magnetic planes: Pick 3 points to bind the parts together (pick 1 point on each magnetic plane) Model embeds as custom parts and include them in components. Create simple components for specific situations. It is faster and easier to model simple components. They are also much easier to use. Avoid creating a ’super’ component to use in every possible situation.
