Introduction

In this chapter

This chapter provides an overview of the Tekla Structures user interface, and its basic features. It also explains how to use common commands.

Audience

This chapter has been written for beginners. This is the best chapter to start with to gain a basic understanding of Tekla Structures. If you are already familiar with Tekla Xsteel, you can move on to Chapter 3, Parts, to read about materials other than steel.

Contents

This chapter is divided into the following sections: • • • • • • •

General information (p. 7) Screen layout (p. 12) Toolbars (p. 15) Inputting information (p. 21) Specifying points (p. 26) Selecting model objects (p. 30) Using commands (p. 34)

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.

TEKLA STRUCTURES - MODELING MANUAL Introduction

7

3D model

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:

8

•

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

•

Catalogs of available material grades, profiles, and bolts.

•

Macros 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.

•

Integrated analysis and design with STAAD.Pro.


Easy to use

•

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.

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. Tekla Structures also supports undo and redo, so you can test solutions, and revert to the original, if needed.

Global but localized

Tekla Structures is used worldwide. It is available in a wide range of languages, and adapted to local requirements.

Languages and environments When you install Tekla Structures, you can choose the language(s) and the environment(s) you want to use. Language

Tekla Structures 11.0 software and manuals are available in the following languages: • • • • • • • •

Chinese – simplified (chs) Dutch (nld) English (enu) French (fra) German (deu) Japanese (jpn) Portuguese – Brazilian (ptb) Spanish (esp)

Some language-dependent file and folder names include the abbreviations listed above. Environment

The environment means region-specific settings and information. It defines which profiles, material names, default values, connections, wizards, variables, reports, and templates you use.


9

The environments available in Tekla Structures 11.0 are: • • • • • • • • • • • • • • • • • • • • •

Australasia Brazil China Europe France Germany India Japan Korea Netherlands Portugal South Africa South-East Asia Spain Switzerland (French) Switzerland (German) Switzerland (Italian) Taiwan United Kingdom United States (Imperial) United States (Metric)

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

Multiuser mode

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

Tekla Structures editors Tekla Structures includes the following editors: Model, Drawing, Symbol, Template, Custom Component. 10


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.

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.


11

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:

Select switches determine selectable objects. Steel beams, columns, plates.

Snap settings Commands for control which creating views. points you can snap to and pick.

Pull-down menus contain all commands.

Concrete footings, beams, columns.

Toolbars can either be docked or floating.

Status bar displays the prompt and the status of some settings.

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. For additional definitions of terms, see the Glossary (p. 185). Menu bar

12

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. When you move the mouse pointer over an icon, a tooltip displays the name of the icon. 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. 15).

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. 21). 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. 30).

The two circled switches control whether you can select model objects and/or objects created by components. Either or both of these switches must be active for the other switches to work. 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. 26).


13

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 the selected objects

For more information, see Settings (p. 126).

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. Use the commands on the Window menu to control the windows. Command

You cannot use the Cascade window, Tile horizontally, and Tile vertically commands for windows that you can move outside the Tekla Structures window. For more information on moving part and component basic views and zoom windows across the entire Windows desktop, see XS_MDIVIEWPARENT, XS_MDIZOOMPARENT, and XS_MDIBASICVIEWPARENT in the online help. You can control the representation of a model in the windows using the commands on the View menu. See Representation (p. 47) and Views (p. 45).

1.3 Toolbars The toolbars contain icons which give easy access to some of the most frequently-used commands. Using icons

Most of the Tekla Structures icons work as follows: • •

A single-click executes the command. A double-click displays the properties dialog box of the object type, and executes the command.

Managing toolbars Toolbars can either be floating or docked, i.e. located at the edge of the program window. To move toolbars, click the handle on the left or upper edge of a docked toolbar (or the title bar of a floating toolbar), and drag the toolbar to a new location. To drag toolbars beyond the program window, hold down the Ctrl key while dragging. The toolbars remain floating. You can resize floating toolbars by grabbing any edge with the mouse pointer. To display or hide a toolbar, click Window > Toolbars and click the toolbar name. Visible toolbars have a check mark against their name. For more information on menus and toolbars, and how to customize them, see Customizing the user interface in the online help.

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

•

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.


23

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. 24) and Save, Load, Save as, Help (p. 25). 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. 25). 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. 25).

24


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.

Button

Description

Save as

Stores the dialog box properties with the name given in the field. 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.


25

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. Open a part properties dialog box, e.g. Beam properties. Check only the Material field. Click Modify.

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

Description

Arrow keys

Move the pointer within fields.

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

26

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. 27).


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

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. Icon

You can also key in position coordinates to snap to using the Enter a numeric location toolbar. For more information, see Snapping (p. 140).


Snap settings The first list box on the Snap settings 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 Setup > Snap settings... to open the Snap dialog box. Use it 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. On the Setup menu, click 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. Binding objects to planes

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

1.6 Selecting model objects To use Tekla Structures effectively, you need to know how to select objects and use select switches. Select filter settings also affect which objects you can select. See Select filter (p. 124).

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.

30


You can use the following techniques to modify the current selection: 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. 1

2 Crossing window selection

Drag the mouse from right to left to select all objects totally or partly within that rectangular area. 2

1 Assembly or cast unit

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

For more information, see Select filter (p. 124).

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

Pop-up menu

•

Single-click an icon just to execute the command.

•

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: •

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:

34

•

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

To create objects: 1.

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

2.

Enter or modify the object properties.

3.

Click Apply or OK. See also Common buttons (p. 24).

4.

Pick points to place the object(s).

To position objects without defining their properties: 1.

Single-click an icon, or a menu command.

2.

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. 35). 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. 36).

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

To modify objects: 1.

Double-click one of the objects you want to modify to open the object properties dialog box.

2.

Modify the properties. See also Modify filter checkboxes (p. 25).

3.

Select the remaining object(s) to modify. See also How to select objects (p. 30). TEKLA STRUCTURES - MODELING MANUAL Introduction

4. See also

Click Modify.

For information on how to resize and move objects, see Handles (p. 72) and Copying and moving objects (p. 119).

Using commands simultaneously Transparency

You can use some Tekla Structures commands transparently. This means that you can execute these commands while another command is still running. For example, the commands on the Points, Window, and Setup menus are transparent.

Ending commands To cancel or end commands, do one of the following:

36

•

Click the Interrupt icon

•

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

•

Press the Esc key.

•

On the Edit menu, click Interrupt.

Introduction

Getting Started

When you start a new Tekla Structures model, the first objects you create are grids, views, and points. 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, to gain a basic understanding of Tekla Structures.

Contents

This chapter is divided into the following sections: • • • • •

How to use this chapter

Basics (p. 37) Grids (p. 43) Views (p. 45) Points (p. 53) Construction lines and circles (p. 55)

You can start by creating either Views (p. 45) or Grids (p. 43).

2.1 Basics In this section

This section presents basic Tekla Structures vocabulary and concepts so that you can start modeling. For additional definitions of terms, see the Glossary (p. 185). The illustration below shows the modeling guides you use in Tekla Structures windows.

TEKLA STRUCTURES - MODELING MANUAL Getting Started

37

Green dashed lines outline the work area.

Points are red outside the view plane.

Cyan grid is on the view plane.

Green cube is in the global origin.

Arrow symbol indicates the work plane.

Points are yellow on the view plane.

View

To see your Tekla Structures model from virtually any angle, you can move and rotate the model. See Examining the model (p. 109). 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 green cube in a model view represents the global coordinate system and lies at the global point of origin. In Tekla Structures, both the global and local coordinate systems are cartesian, with three axes (x, y, and z) perpendicular to each other.

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 right-hand 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.

38


Grid and view plane

Cyan 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 an 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.

Select the model from the Model directories list on the right of the Open model dialog box.

3.

Click OK to open the model.

Use the Directories list on the left of the Open model dialog box and the following techniques to browse files and folders above and below the current folder: •

One dot at the end of an entry indicates the current folder.

•

To move up, double-click an entry followed by two dots.

•

To move down, double-click the desired entry.

•

Enter directory paths in the Filter field and click the Filter button.

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

Click File > New... or

. The New model 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 model dialog box, click after the path, for example C:\Tekla Structures_Models, in the field at the bottom of the dialog box. Then type \ and the model name in the field.

3.

Select the Create default view and grid checkbox if you want Tekla Structures to automatically create a grid and a view using the standard properties. See Working with grids (p. 44).


39

4.

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.

The Directories list and the Filter field and button in the New model dialog box work in a similar way to those in the Open model dialog box. See Opening a model (p. 39). Every model must have a unique name. Tekla Structures does not allow duplicate model names. Do not use special characters ( / \ ; : | ) in model names.

Project setup Update the project information at the beginning of a project to make reports and drawings to display the correct information automatically. To update the project information, click Properties > Project.... The Project dialog box appears. Tekla Structures displays this information in different reports and drawing titles. The names in the image below refer to template fields, which you can use when designing your own reports and templates.

Before starting a new project, read also Using Tekla Structures effectively in the online help.

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.

Work plane

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.


41

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

Icon

Description

Work plane...

Sets the work plane parallel to xy, xz, or yz plane.

With one point

Sets the work plane according to one picked point.

With two points

Sets the work plane according to two picked points.

With three points

Sets the work plane according to three picked points.

To view plane

Sets the work plane to be equivalent to the view plane of a picked view.

To part plane

Sets the work plane on the front, top, back, or bottom plane of a picked part. The icon is for the top plane.

Saving a model and exiting Tekla Structures To save a model, click File > Save or

.

Save as

Click File > Save as... to save a model with a new name, or to give a new model a specific name.

Autosave

Tekla Structures automatically saves the model at set intervals. To set the interval and define the location of autosave files, see Autosave in the online help. Saving models differs in multiuser mode. See Multiuser mode in the online help.

Exit

42

To exit Tekla Structures, close the Tekla Structures window, or click File > Exit. A confirmation dialog box appears and you can choose whether or not to save the model.


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 cyan dash-and-dot lines. See also View plane (p. 46). You can have more than one grid in a model. You may want to create a largescale grid for the entire structure, and smaller grids for some detailed sections. Grids are always rectangular. You can create rotated grids by changing the work plane. To position objects in a circular pattern, use construction circles. See Construction lines and circles (p. 55).

You can pick grid lines and grid line intersections. See also Specifying points (p. 26).

Grid properties To access the Grid properties dialog box,

Grid coordinates

•

On the Points toolbar, double-click or

•

click Points > 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

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.


43

Line extensions

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

Line extensions

Work plane origin

Working with grids Automatic grid

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 grids To manually create a grid: 1.

Click Points > Grid... or .

2.

Fill in the properties described in Grid properties (p. 43).

3.

To create the grid, click the Create or OK button.

This is all you need to do so far if you have started your model by creating the grid manually. As you do not have any views yet, you cannot see the grid. See Views (p. 45). If you have already created views as described in Views (p. 45), Tekla Structures prompts you to pick the origin after 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. 44


Initially, a small grid appears in the bottom left corner of the view. To enlarge the grid, click in the view to activate it. Then, click View > Fit work area.

Modifying grids To modify a grid, double-click any of the grid lines. The Grid dialog box appears, and you can modify the properties. Click the Modify button to save the changes.

Deleting grids To delete a grid, click any grid line, right-click and select Delete from the popup menu. When you delete a grid, do not have any other object(s) selected. Tekla Structures only deletes the objects, not the grid.

See also

Grids (p. 43)

2.3 Views Introduction

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

of the entire structure of selected part(s) and component(s) along the grid lines

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 view-specific 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. 46).

You can have up to nine views on the screen at the same time. If the view does not appear, check how many views you have open. To switch between views, press Ctrl+Tab.


45

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: XY

XZ

ZY

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 > Translate... from the popup menu. See Copying and moving objects (p. 119) and Move (p. 121). 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. 51). When you exit the model, Tekla Structures only saves named views. Tekla Structures does not save unnamed views when you close them.

46


In multiuser 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.

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 Wire frame or Shaded wire frame option in the rendered views. Rotating the model in the rendered views is very convinient with the mouse.

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

Wire frame

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

•

Shaded wire frame

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


47

•

Hidden lines

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

•

Rendered

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

•

Rendered (light colors)

Parts are not transparent. Part surfaces are displayed more in lighter colors 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.

48


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 Window > 3D / Plane to switch between 3D and plane view.

Rotation

Rotation is view-specific. You can rotate the model in 3D views using the mouse and keyboard (see Rotating the model (p. 114)), 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.

View depth

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 in views (p. 51).

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. TEKLA STRUCTURES - MODELING MANUAL Getting Started

49

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. 46). 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 icons on the View toolbar, or click View > Create view.... The following table lists the commands for creating views and gives a short description of each one. Command

Click

.

•

Click View > Named views... to display the Views dialog box.

Tekla Structures lists all invisible named views on the left, and all visible views on the right. To display or hide views, select the view(s) and use the arrows between the lists. You can move selected views between both lists using the middle arrow. To delete a named view, select the view and click Delete. See also Naming views (p. 46).

Displaying and hiding objects in views The visibility of objects in views depends on the following settings: • • • •

work area view depth view setup view filter

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. 52)).


51

Object representation

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

Double-click the view.

2.

In the View properties dialog box, click Display.... The View setup dialog box appears

52


2.4 Points Introduction

To place an object in a model you may need to pick points. Tekla Structures automatically creates points at part ends, and grid line and part intersections. To place an object where no lines or objects intersect, you have the following options to place objects: • • •

Use snapping commands. See Snapping (p. 140). Use construction lines and circles. See Construction lines and circles (p. 55). 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 Inquire > Object... and select the point. See also Inquire (p. 116). 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 Select filter (p. 124).

Coordinates

The point infomation 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.


53

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

2.5 Construction lines and circles Construction 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 lines and circles 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 Points menu. The following table lists the commands for creating construction objects and gives a short description of each one: Command

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 slab

The main steel parts are: • • • • • • •

beam curved beam orthogonal beam polybeam column twin profile contour plate

In this chapter

This chapter explains how to create and modify parts using different materials and profiles. It also includes a general description of part properties and an overview of part commands. You can find step-by-step instructions for all these commands in the online help.

Assumed background

We assume that you have read Chapter 1, Introduction, or have comparable knowledge of Tekla Structures. Before you start to create parts, you need to create grids, views, and points, as explained in Chapter 2, Getting Started.

Contents

This chapter is divided into the following sections: • • • • • • •

Part properties (p. 58) Cast units and assemblies (p. 67) Numbering parts (p. 68) Part location (p. 71) Surface treatment (p. 78) Steel part commands (p. 84) Concrete part commands (p. 85)

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. 122).

In reports and drawings

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

58


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.

Finish

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

Class

Use Class to group parts. To display parts of different classes in different colors, click Setup > Colors... and select By class in the Colors list box. See also Colors (p. 134).

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


59

Standard profiles

When you first start Tekla Structures, the profile catalog contains standard, environment-specific 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. 177). If you want to define alternative prefixes for parametric profiles, see Customizing parametric profiles 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. When you save user-defined profiles in the profile catalog they become library profiles. To create your own profiles, see Adding a standard (fixed) user-defined profile in the online help.

60


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.


61

Library profile

If you select Library profile in the Profile category list box, you can select a profile from the tree. The tree lists all the profiles contained in the profile catalog. Library profiles are grouped in the tree according to rules (such as profile type) which you can define and modify. For more on how to modify the profile catalog and rules, see The profile catalog in the online help.

Rules and details

If you select the Show empty rules checkbox, Tekla Structures includes the rules which do not contain any profiles or subrules in the tree. To see all the properties of profiles, select the Show details checkbox. Tekla Structures only displays cross section information for user-defined profiles.

62


Parametric profile

Use Parametric profile in the Profile category list box to review profile shapes according to profile type, subtype, and prefix, and enter profile dimensions in the Value column. Select a profile, then click Apply or OK.


63

You can also 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. 177).

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...

64

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.


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. 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.


65

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 Tools > Numbering > Preliminary marks when you number parts. To check the preliminary mark of a selected object, click 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.

66


3.2 Cast units and assemblies Steel assemblies

Tekla Structures creates 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. 87). 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. There are no connecting welds or bolts in cast units, so you need to specify which parts form the cast unit. See Working with cast units (p. 68).

Main parts

The main part in a steel assembly has other parts welded or bolted to it. 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.

Checking contents

Cast units can include reinforcement, cast-in fittings, and steel assemblies, as well as concrete parts. To visually check the objects in a cast unit or an assembly, click Inquire > Assembly. Pick 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. 116). Tekla Structures uses different colors to highlight different objects: Object type

3.3 Numbering parts Introduction

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: • • •

Connecting a drawing with the right part, cast unit, or assembly. Reporting the properties of identical parts, cast units, and assemblies. Identifying part information for export another program.

See Numbering (p. 135) for information on how to set up and carry out numbering.

68


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

For example, if you define a numbering series with the prefix P and starting number 1001, Tekla Structures numbers that series P1001, P1002, P1003, ... 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). Use the variables XS_CONCRETE_PART_NUMBERING_PREFIX and XS_CONCRETE_PART_NUMBERING_START_NUMBER to define the prefix and starting number for concrete parts. See Appendix C, Variables in the online help. When you run numbering (see Numbering (p. 135)), 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 and assemblies

Tekla Structures numbers concrete cast units and steel assemblies using the same principles as it follows when numbering parts. By default, A is the prefix for assembly marks. The default starting number is 1. 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. 67). 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. TEKLA STRUCTURES - MODELING MANUAL Parts

69

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.

Numbering series Name

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

Profile 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.

70


Additional properties

Tekla Structures treats parts as different, and so numbers them differently, if the following properties differ: 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 fittings

If you select the Components 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.

See also

For more information on numbering settings, see Numbering (p. 135).

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). TEKLA STRUCTURES - MODELING MANUAL Parts

71

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.

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.

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. 121). If you have Drag and drop on, just drag the handle to a new position. See Drag and drop

(p. 128). 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. 30).

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

Middle Right Left

You can also define the distance of a part from its original reference line. See Part reference point (p. 71). 72

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. Radius

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. The sector angle must be less than 180 degrees.

Plane

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

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 Tekla Structures handles solids in the online help.

Introduction

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. 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.

Contents

This section includes the following topics: • • • •

Bolts (p. 87) Welds (p. 94) Fine-tuning part shape (p. 101) Detailing commands (p. 106)

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 the Defining bolts and welds section in the Detailing Manual. You can create different part marks for holes and bolts in drawings.

TEKLA STRUCTURES - MODELING MANUAL Detailing

87

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. Type determines assembly

Tekla Structures only creates assemblies from parts with the fastener type Workshop (bolts assembled in a workshop). The order in which you select parts when creating the connection determines the main and secondary part(s) of the assembly. The first part you pick usually becomes the main part in the assembly.

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 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.

Bolt dist X: 75 175 Bolt dist Y: 100 100

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.

Apply a component.

2.

Explode the component.

3.

Modify the bolt group.

Changing bolt parts You can change which parts a bolt group connects using the command Edit > Bolt 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 Oversized Slotted

Creating round holes To create a round hole, follow the steps in Creating a bolt group (p. 88). Tekla Structures calculates the diameter of a round hole as the sum of: • •

Bolt size Tolerance (hole)


89

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

Clear 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 90


You indicate the x direction of the bolt group when you create the bolt group (see Creating a bolt group (p. 88)).

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.

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

Select the checkboxes against Parts with slotted holes to indicate which plies of connection get oversized holes.

2.

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.

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

Array for rectangular xy list for any shape Circle for circular

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

Shape

Bolt dist X

Bolt dist Y

Array

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

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

xy list

x coordinate of each bolt, from the bolt group point of origin.

y coordinate of each bolt, from the bolt group point of origin.

Circle

Number of bolts.

Diameter of the bolt group.

To create a single bolt, set Bolt group Shape to Array and enter "0" for both bolt distances.

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 Cut length Extra 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 fullthreaded 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.

92


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).

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 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

Offsets

Top

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. TEKLA STRUCTURES - MODELING MANUAL Detailing

93

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. • • • Example

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

An example showing the parameters of a bolt group.

Bolts created using the bolt properties: • • •

Bolt group Shape = Array, Bolt dist X = 100 100, Bolt dist Y = 200 Slotted hole X = 28, Bolt size = 20, Tolerance = 2 (overall dimension = 50) Starting point, Dx = 100.0

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 Tekla Structures only forms assemblies from parts connected using workshop welds.

94


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. Visibility in views

To have welds visible in views, open the View setup dialog box and set weld visibility to Exact. See Displaying and hiding objects in views (p. 51). Tekla Structures displays all weld types in a similar way.

Creating welds You can create the following types of welds: •

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. If you move welded parts, polygon welds do not move with them.

For detailed instructions on how to create welds, see the online help.

Weld symbols in drawings Weld properties

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 The other sides only Both the arrow and other sides

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.

96


Weld properties This section describes weld properties. Size

See the image below.

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. 98)

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. 101).

Contour

The fill type contour of a weld can be:

Finish

•

None

•

Flush

•

Convex

•

Concave

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

G (Grind) M (Machine) C (Chip)

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=@.


97

Root face and RFT

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). 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. Tekla Structures only forms assemblies when you use workshop welds.

Position

See Weld position (p. 99).

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 antimatter 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. 98).

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

4.3 Fine-tuning part shape Introduction

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

Chamfer Some part corners can be chamfered. You can use the Chamfer command to shape the following parts: polybeam, contour plate, strip footing, concrete beam, concrete slab, concrete panel. TEKLA STRUCTURES - MODELING MANUAL Detailing

101

Tekla Structures creates chamfers using the current properties in the Chamfer properties dialog box. Click 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.

Set the chamfer properties.

2.

Click Detailing > Chamfer.

3.

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

See 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. 72) to make the part longer.

102


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. 72) or use the Fitting (p. 102) command instead. You can create the following types of cuts for a part: • • • Line cut

Line cut Polygon cut Part 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 a blue cut symbol. Exact representation (without symbol)

Fast representation Cut symbol


103

By default, line cuts do not affect beam length in NC files. To change this, see online help. See 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 as an antimatter part indicated by dot-dash lines. You must create cuts in a plane view. Exact representation (without symbol)

Fast representation

Antimatter part

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

104


Hidden lines Cut symbol

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.

Part add Click Detailing > Part add to model complex parts (e.g. folded plates) that are otherwise difficult to model. You can also use Part add to model prefabricated parts that are delivered to the workshop already attached to profiles. Part adds can also be nested, i.e., a part add can be added to an part add. Cuts and fittings can also be applied to part adds. The Part add command creates a part to be attached to the selected main part. Tekla Structures deletes the part you use to create the attached part when it creates the part add. The Part add only gets one mark in drawings. The attached part is shown in magenta. See online help for more detailed information on using this command.


105

Polygon shape To modify the shape of a part, click Edit > Polygon shape. You can use this command on the following parts: • • • • • •

polybeam contour plate strip footing concrete beam concrete slab concrete panel

Tekla Structures prompts you to Pick polygon corner: 1.

Pick one of the corners of the part.

2.

Pick a new location for the corner.

3.

End the command by picking any existing corner.

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

4.4 Detailing commands To “fine-tune” or detail your model, use the icons on the Detailing and Steel toolbars, or select commands from the Detailing menu. The following table lists the commands for detailing and gives a short description of each one. Detailing command

2.

Click Tools > Clash check.

3.

If parts or bolts collide, Tekla Structures highlights them in yellow and displays the clash check log in the List dialog box.

4.

To quickly locate and view colliding parts in the model, select a 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.

If no there are no colliding parts, Tekla Structures displays the message No collisions detected on the status bar. Set bolt clearance

To define bolt clearance for clash checking, click Setup > Bolt 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 clearance

118


The clash checking clearance area is shaded 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 Setup > Save defaults. If Tekla Structures cannot find the bolt head or nut diameter in the bolt catalog, it uses the shank diameter.

Compare Use this tool to compare two assemblies or parts. To compare parts, select two parts in the model. Click Tools > Compare > Parts. To compare assemblies, click on a part in each assembly. Click Tools > Compare > Assemblies. Tekla Structures displays the results on the status bar. If you need more detailed information on assemblies or parts, use Inquire (p. 116).

5.3 Copying and moving objects Use the Copy and Move tools to translate, rotate, or mirror objects. Copy creates a new object, leaving the original object in its original position. Move relocates the original object.

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 fully mirror objects if they include connections that contain, for example, asymmetricallypositioned parts.

5.4 Filter Introduction

The Filter option is useful when you want to perform an operation on several objects or properties at the same time. Use the Select 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. This section describes the Select and View filters and explains how to use filters in dialog boxes.

Filtering techniques Filter by multiple properties

You can define filters containing several properties. You can also have multiple filtering criteria for each property. If you use multiple criteria, separate the strings with blank spaces (e.g. 12 5).

Set filtering on

To set filtering on for a particular property, select the checkbox next to the property name.

Example

You can use the select filter to create a report of parts in particular phases. To select all parts in phases 1 and 2, set the select filter as follows:

122


Complement filtering

To use complement filtering (i.e.defining which parts not to select), check Not next to the property name and enter the filter criteria.

Example

If you only want to create connections between certain parts, use complement filter to filter out the remaining parts. For example, the filter below selects all parts except for bracing (which have the name "BRACE").

Select switches also affect the selection of objects. See Controlling the selection (p. 32).

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*.

? (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


123

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.

Select filter Use the Select 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. 32)). To use the Select filter on an object, the object must be visible in the relevant view. See View filter (p. 125) for more information.

Standard select filters Tekla Structures contains several standard select filters. The select filter list box on the Select switches toolbar lists both standard and user-defined filters. Displays the Select filter

dialog box. To apply a filter, select one from the list.

124


Standard filters always appears first on the list

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

Use the Display select filter dialog box icon, or Setup > Select filter to open the Select 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 Select 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 Select filter to select them. Use the Select filter to select the parts you want to carry loads.

Select filter dialog box To display the Select filter dialog box: •

Use the Display select filter dialog box icon

•

click Setup > Select filter.

, or

Use object properties to define whether or not an object can be selected.

View filter Use the View filter to define which objects are displayed in a view, according to object properties. View setup, work area, and display depth also affect whether an object is visible. See Displaying and hiding objects in views (p. 51). To display the View filter dialog box: 1.

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

2.

Click Filter.


125

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. 123).

5.5 Settings In this section 126

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


Units and decimals To configure how units and decimals are input, output, stored and displayed, click Setup > 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 Model data and Sections and materials tabs. Output data appears on the Results tab (output data only relates to structural analysis).

Modeling functions

The settings on the Model data 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 Sections and materials 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.


127

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

Inches in decimals (e.g. 300.5") Feet in decimals (e.g. 62.7') Fractional notation (e.g. 60'-6")

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. 128) Drag and drop (p. 128) SmartSelect (p. 129) Xmouse (p. 129) Xsnap (p. 129)

Pan Pan toggles the function of the middle mouse button between panning and scrolling. To switch between scrolling and panning, click Setup > Middle button pan, or Ctrl+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. Activate

To toggle Drag and drop on and off, use the keystroke D, or Setup > Drag and drop. It remains active until you turn it off. 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.

128


SmartSelect With SmartSelect active, you can drag and drop parts or assemblies without selecting them first. Activate

To toggle SmartSelect on and off, use the keystroke S, or Setup > SmartSelect. It remains active until you turn 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 Setup > Xmouse. A checkmark appears next to the menu option if Xmouse is already active. Using Xmouse

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. 113).

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 keystroke T or Setup > 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. 26).

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.


129

Example

For example, you have a large project on which several users will work simultaneously in single-user 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

To work with phases, click Setup > Phase manager... or Properties > Phase number.... The Phase manager dialog box appears.

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

130

Button

Description

Filter

Lists the phases by the number and/or name criteria you enter. See Filter in dialog boxes (p. 126).

Set current

Makes the selected phase the current phase. Tekla Structures assigns all objects you create after setting a phase to current to the current phase. The @ character in front of the phase number indicates the current phase.

Select by objects

Highlights the phases associated with the objects currently selected in the model. Use this button to identify the phase of an object.


Additional properties

Button

Description

Add

Creates a new phase.

Delete

Deletes the phases you select from the list.

Select by phase

Selects and highlights the corresponding objects in the model if you have selected associated phases on the list.

Modify phase

Changes the phases of the selected objects to the phase selected on the list.

You can add more phase properties, which will appear as extra columns on the list. Tekla Structures considers phase properties to be user-defined attributes, so you can define the names of phase properties in the objects.inp file. See Adding properties. To use phase properties in reports and templates, use the syntax PHASE.ATTRIBUTE_NAME in the phase property field name.


131

Options Use Options to set various default values for numbering, coefficients, profile names and connections. To open the Options dialog box, click Setup > Options....

5.6 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 Setup > Numbering:

You can use various numbering options: 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.


135

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 the online help.

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

Create three identical beams with the numbering series prefix P and start number 1.

2.

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:

136

•

Compare to old: P1

•

Keep number if possible: P2

•

Take new number: P3


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. 135)). Pop-marking

Pop-marking for NC files also affects numbering. When pop-marking is active, 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.

Log file

Click Tools > Display log file > Numbering history log for a report showing the numbering history. For information on how to interpret the log file, see Log files in the online help.


137

Applying numbering

To apply numbering, click Tools > Numbering. You have the following options: Option

Result

Modified

Assigns marks to all modified and new parts and assemblies.

Clear selected (reinforcing bar only)

Deletes current reinforcing bar position number.

Preliminary marks

Saves current part position number as preliminary marks for selected parts.

Create control numbers...

Assigns control numbers to parts.

Lock/Unlock control numbers

Locks or unlocks control numbers. See Locking and unlocking control numbers (p. 139).

Assigning control numbers to parts Control numbers are properties that identify the location of parts in a model. Use the Create control numbers (S9) macro to assign control numbers to parts. You can have Tekla Structures assign consecutive control numbers to all parts in the model, to selected parts, or only to parts in a specific numbering series. Each part gets a unique control number.

138


To display control numbers in drawings, reports, or when you use the Inquire > Object... command, select the property, ACN.

For more information on how to use this tool, see the online helpSee

To find out how to display control numbers in drawings, see User-defined attributes in marks in the Drawing manual. Locking and unlocking control numbers (p. 139)

5.7 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. 27) Numeric snapping (p. 140) Orthogonal snapping (p. 141) Tracking (p. 142) Temporary reference points (p. 142)

See also Snapping examples (p. 142).

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

To display the toolbar, initiate a command that requires you to pick positions, and then do one of the following: • • 140

Start entering the coordinates using the keyboard. Click Setup > Enter a numeric location and select an option.


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 (Setup > 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. TEKLA STRUCTURES - MODELING MANUAL Settings and Tools

141

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. 142).

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

Initiate a command that requires you to pick positions.

2.

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. 142).

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. 141). 142


In the illustration below, we snapped to a grid line midpoint and tracked along the tentative line for 1000 units.

1000

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

4000


143

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

-1000

Reference points

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.

500

Locking coordinates

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. 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.

150


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: Option

Description

Sequence name

If you want to assign values for existing user-defined attributes with the sequencer, enter exactly the same name as in the objects.inp file. For example, PRELIM_MARK for preliminary marks.

Max number

The highest number to use in the sequence. Objects are numbered from 1 up. If you select an object that has already been included in a sequence, Tekla Structures prompts if you want to override the existing number. If you click Yes, Tekla Structures gives the next available number to the object.

Delete

Deletes the sequence. If there is only one sequence in the list, the name of the empty sequence remains.

Advanced Modeling

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. 155) Parametric modeling (p. 166) Warping, cambering, and shortening parts (p. 168) Modeling tips (p. 173)

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.

Sketching cross sections To sketch a cross section: 1.

Click File > Catalogs > Profiles > Sketch parametric cross section. Tekla Structures opens the: • •

2.

Cross section sketch editor view and Sketching toolbar Variables and Sketch browser dialog boxes

Use the following tools on the Sketching toolbar to sketch the outline of a cross section, and holes in the cross section

Command

Icon

Description

Sketch polyline

Sketch lines.

Sketch arc

Sketch an arc.

Sketch circle

Sketch a circle.

Ensure that you create a closed shape: • •

156


Try to start sketching at a point that is easy to pick, such as a gridline intersection. If necessary, use the Coincident constrainttool to close it.

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

Using constraints to lock cross section shape (p. 157) Adding dimensions to cross sections (p. 159) Naming, saving, and closing cross sections (p. 161) 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.

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

Where 2 lines meet Between line segments when you draw them with the Sketch polyline tool. 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.

Locks the position and angle of a line, so that other constraints do not affect it. TEKLA STRUCTURES - MODELING MANUAL Advanced Modeling

157

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. 156) You can choose to create chamfers in your cross section. Then you need to add dimensions, and save your sketch. See: • • •

Defining chamfers (p. 158) Adding dimensions to cross sections (p. 159) Naming, saving, and closing cross sections (p. 161) Tekla Structures will not save a cross section that does not have dimensions.

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

158


.

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

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

2.

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


159

The Sketching toolbar includes the following tools to create dimensions. 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 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:

The Sketching toolbar includes the following tools to create and use variables: Command Display variables

Icon

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.

160


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:

Using snapshots

1.

Using any image editor, e.g. Paint, create an image that shows the shape and dimensions of the profile.

2.

Save the image in the folder ..\TeklaStructures\11.0\nt\bitmaps, using the cross section name as the filename, with the file extension .bmp. For example, mysketch.bmp.

To use a Tekla Structures snapshot as a picture: 1.

Open the sketch in the cross section sketch editor view. If necessary, click in the sketch to ensure it is the active view.

2.

Press F12 on your keyboard to take a snapshot of the sketch, without the borders.

3.

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

4.

Copy the renamed snapshot file to the folder ..\TeklaStructures\11.0\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. 159).

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

165

6.2 Sketching tools The following table lists the sketching tools and gives a short description of each one. For the detailed instructions, see the online help.

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. 166) Creating variables (p. 167)

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. To create dependencies, use the following tools on the Points toolbar:

166


Command Create reference distance

Icon

Description Creates a reference distance between model objects, which you can include in formulas in the Variables dialog box. Works the same way as Create reference distance in the Custom component editor. For more information, see Defining variables and Creating reference distances in the Detailing manual.

Create distance

Binds a handle on a model object to up to 3 planes on other model objects, at a fixed distance. Illustrates the distance in the model view. Works the same way as Create distance in the Custom component editor. For more information, see Defining variables and Creating distance variables in the Detailing manual.

Creating variables Use variables to define the properties of a model object, such as a beam or column. Variables can define fixed properties, for example, the name of a column. Or they include formulas, so that Tekla Structures calculates the property value each time you use the model object.


167

The Tools toolbar includes the following parametric modeling tools for defining and editing variables: U

Command

Icon

Display variables

Description View, add or change variables in model objects. You can use these variables to calculate the properties of related model objects. See also Using variables to define cross section properties (p. 160). Works the same way as Display variables in the Custom component editor.

Display model browser

Opens the model browser, which shows the elements in a model object. Use to copy absolute values or references and use them as variables in parametric calculations. Works the same way as Display custom component browser in the Custom component editor.

Modeling tips This section includes the following topics: • • •

General tips (p. 173) Detailing (p. 173) Working with custom components (p. 174)

General tips Keep ’Move’ or ’Copy’ dialogs 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.

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

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. TEKLA STRUCTURES - MODELING MANUAL Advanced Modeling

173

Working with custom components These tips will help you to efficiently create, save, and share parametric and nonparametric 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

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_HANDLES to 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.

174


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:

Using 3 magnetic planes:

Pick all 10 handles to bind the parts together.

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.

TEKLA STRUCTURES - MODELING MANUAL Glossary

Catalog Catalogs contain predefined information on all available profile, material, bolt, and bolt assembly properties, and plotter settings. Center of gravity The location of the resultant of gravity forces on an object or objects. Sometimes called center of mass. Check dimension A minor dimension that controls model accuracy. Classifier Tekla Structures contains two classifier features: •

Drawing Classifier for customizing the appearance of parts, marks, and dimensions in different drawing types.

•

NC file classifier for sorting NC files of different parts to machinespecific folders.

Click See Single-click (p. 197). Clone Use to copy drawings. For example, to copy an edited drawing for a similar part, create a drawing for one truss, edit the drawing, then clone it for other similar trusses. Now you only need to modify the cloned drawings where the trusses differ. Command An instruction you give to the computer to do something. You usually select a command from the menu bar. Component A tool that automate tasks and group objects so that Tekla Structures treats them as a single unit. Components can be: • • • •

connections details macros user-defined (custom components)

Components adapt to changes in the model, so that Tekla Structures automatically modifies a connection if you modify the parts it connects, for example.


187

Connection Connection is a subtype of component. It connects two or more parts and automatically creates the necessary plates, fittings, bolts, welds, etc. Examples of connections: end plate, bolted gusset plate. In some cases we also use the term connection for connections and details together. Constraint Tools that you use in the Cross section sketch editor view to refine and lock custom cross sections. Contour plate A plate that you create by picking its corners. Coordinate system The origin and three axes (x, y, and z) perpendicular to each other. See also Global coordinate system (p. 190) and Local coordinate system (p. 192). Cursor A graphic symbol displayed on the screen to show the location of the mouse. Custom Component Editor The Tekla Structures editor you use to create your own connections, details, and parts, and define their properties. In the Custom Component Editor, you can build dependences between objects to make custom elements parametric and adaptive to changes in the model.

D Database The model database (the *.db1 files) contains all the information about the physical model. The *.db2 file is the numbering database. Default Any predefined setting or value. In connections, default values have a specific meaning. AutoDefaults can only replace fields that have default values with new values from the Autodefaults settings. Design group A group of parts that have the same name and profile. Tekla Structures uses design groups when it searches for the optimal profiles for parts. It assigns the profile of the governing part to all parts in the design group.

188


Detail Detail is a subtype of component. It connects to a part and automatically creates the necessary plates, fittings, bolts, welds, etc. Examples of details: base plates, stiffeners, lifting hooks. See also Component (p. 187) and Connection (p. 188). Dialog box 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 to display its properties dialog box. Double-click To click the left mouse button twice in rapid succession. Double-click an object or an icon to display its properties dialog box. Also use double-click to overwrite the contents of a field in a dialog box. Note that this only highlights one word at a time. Drag To move an item on the screen by selecting the item, then pressing and holding down the mouse button, while moving the mouse. For example, you can move a window to another location on the screen by dragging its title bar. Drawing Editor The Tekla Structures editor you use to edit drawings. DSTV2DXF A separate program that converts NC files in DSTV format to DXF format. DWG The standard file format for AutoCAD drawings.

Extrema Rectanglular boundaries. For example, these might specify the content displayed in drawing views.

F Flag A code that shows the status of a drawing (issued, frozen, modified, etc.). Tekla Structures displays these flags in the drawing list. Folded plate An object type and command for plates whose folding form is determined by picking points on the folding line. In the United States, folded plates are also referred to as bent plates. This object type is no longer in use. Instead you should use the Polybeam command to create folded plates. Freeze Freezing a drawing prevents it from being accidently modified. Freeze the drawing when you want to keep modifications in the drawing, such as additional marks and dimensions, even if the model changes. See also Lock (p. 192).

G Global coordinate system Global origin and coordinate axes of a model. Shown by a green cube located at the origin. GOL A specific dimension showing the gage of an outstanding leg. Grid A three-dimensional complex of planes. Tekla Structures shows its projection onto the view plane using cyan dash-and-dot grid lines. GUID A globally unique identifier. Each Tekla Structures member has GUID, which is unique across Tekla Structures models and across any software model. It assures data integrity so that members are identified across projects.

Load combination coefficient See Partial safety factor (p. 194). Load combination Load combination is a process in which some simultaneously acting load groups are multiplied by their partial safety factors and combined with each other according to specific rules. Load combination rules are specific to a design process and are defined in building codes.


191

The result of the load combination process is a load combination. Load group A set of loads that have common partial safety factors in load combination. These loads are caused by the same action. They always occur at the same time and all together. Load group direction The direction of the action that causes the loads in a load group. Load group type The type of the action that causes the loads in a load group. Local coordinate system The coordinate axes (x, y, and z) of a part. For example, the x axis is parallel to the long direction of a part. See also Global coordinate system (p. 190).

We also use lock to refer to the hardware lock delivered with the software. Log A report that Tekla Structures writes when you use the program. Log files can contain error messages, save history, numbering history, etc. Lot A consignment of assemblies to transport to site.

M Macro Macro is a subtype of component. Macro creates the parts to build a structure, such as stairs, but does not connect the structure to existing parts. Macros can include connections and details. See also Component (p. 187). Main part An assembly part to which other parts are welded or bolted, but which is not welded or bolted to any parts. Assemblies can have one or many main parts. The welding and bolting order determines which part is the main part. The chords of a truss are typical main parts. See also Assembly (p. 185).

192


Mark A text or symbol used to identify parts, bolts, welds, and connections in drawings. Part marks are sometimes called piece marks. Master model The shared model you use in multiuser mode. Tekla Structures merges changes in individual user models (plans) with the master model. See also Plan (p. 195). Member A major, load-bearing part. Menu bar An area in the Tekla Structures window, located under the blue title bar, that contains the pull-down menus containing all the Tekla Structures commands.

P Pan To shift the view of a model or drawing without changing the magnification. Parametric profile Profiles that have a predefined, hard-coded shape, with one or more parameters that define the size of the profile. See also Library profile (p. 191) Part The basic component of a model. Parts are large members, such as beams and columns, as well as smaller pieces, such as plates. Partial safety factor A factor by which a characteristic value is multiplied to produce a design value. A factor that takes into consideration the occurrence probability of loadings in load combination. In some context, also referred to as load combination coefficient. Physical model The portion of the product model database that has direct or indirect counterpart in the structure to be build. An example of physical model object is the beam. 194


Pick To use the left mouse button to specify points, or select objects in the model. Plan A user-specific view of the master model. See also Master model (p. 193). Polybeam A continuous beam that you create by picking points to indicate the segments. Segments are straight, but segment intersections can be curved. For example, a beam that follows a zig-zag line is a polybeam. Polyline A continuous sequence of lines. Pop mark Small mark (hole) that the shop uses to weld or bolt secondary parts to the right location on a main part. Pop-up menu Tekla Structures displays a pop-up menu when you right-click. The pop-up menu contains the commands that you can perform on the selected object(s). See also Right-click (p. 196). Position dimension A dimension that presents the location in which the connected part is attached. Primary part An assembly part that has something welded or bolted to it, and that is also welded or bolted to another part. The welding and bolting order determines the primary part. A primary part can simultaneously be the main part of one assembly and a secondary part of another assembly. See also Assembly (p. 185). Prompt A message on the status bar that provides information or asks you to do something. Property A single value or characteristic associated with an object.

R Reduction factor Reduction factors exclude the impractical effects of the simultaneous loads. Reference line The line between the points you pick when you create a part. Rendered view A type of view in which Tekla Structures also displays object surfaces, rather than only object outlines. See also Wire frame view (p. 199). Right-click To click the right mouse button once to display a pop-up menu. The pop-up menu contains the commands that you can perform on the selected object(s). See also Pop-up menu (p. 195). Right-hand rule A rule that indicates the direction of coordinate axes. When you hold the thumb, index finger, and middle finger of your right hand so that they form three right angles, then the thumb symbolizes the x axis, the index finger the y axis, and the middle finger the z axis.

S Secondary part An assembly part that is welded or bolted to another part, and that does not have parts welded or bolted to.

This includes margins, spaces between drawing views, and the location of tables, such as title block, revision table, material list, etc. Template Editor The Tekla Structures editor you use to create and modify templates used in drawings and reports. The Template Editor is also referred to as TplEd. Toolbar A toolbar contains icons which give easy access to the most frequently-used commands. Toolbars are located under the menu bar. Tooltip A small pop-up window that displays the name of an icon. TplEd See Template Editor (p. 198).

U Ultimate limit state A state beyond which the structure no longer satisfies the design performance requirements and which is associated with collapse, or with other forms of structural failure which may endanger the safety of people. 198


UCS User coordinate system in Tekla Structures drawings. The system has origin and x and y axes. User-defined attribute A single value or characteristic associated with an object. User-defined attributes add on to the basic properties of objects. User-defined profile A profile whose cross sections are defined by a user.

V View A representation of a model from a specific location. To see your Tekla Structures model from virtually any angle, you can move and rotate the model, and you can create views of it. View depth The thickness of the displayed slice of model. The objects within the view depth and the work area are visible in the model. View plane The view-specific plane onto which the grids are projected and in which the grid lines are visible. Points located in the view plane are yellow.

W Web Viewer A tool for viewing Tekla Structures models in Internet. Before viewing you need to export the model from Tekla Structures to the Web Viewer format. Wire frame view A type of view in which Tekla Structures only displays object outlines, and objects are transparent. Object surfaces are not displayed. See also Rendered view (p. 196).


199

Wizard A wizard is a series of activities which you could carry out manually but which Tekla Structures can perform automatically to help your work. In Tekla Structures, you can use wizards to create drawings. Work area A limited area that makes it is faster and easier to work on a certain portion of the model. Tekla Structures indicates the work area using green, dashed lines. Objects outside the work area exist but are not visible so you can e.g. confine to a substructure and the views to your model are simpler and quickly updated. Work plane A red coordinate arrow symbol indicates the work plane which is the current, local or kind of a user coordinate system of the model. The arrow symbol defines the xy plane and the z direction is in accordance with the right-hand rule. Work point A creation point of a part. The points at the intersection of a secondary and main part reference line are work points, too. Wrap-around template The way how round tube profiles are represented in single-part drawings.

X Xmouse A feature that activates the view window when you move the pointer over the view. Without Xmouse you should click the view to activate it. Xsnap A feature that 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.
