1.1 About Tekla Structures 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. 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. 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.

Single-user mode vs multi-user mode Tekla Structures can be used in either single-user or multi-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. If several users will work with a model simultaneously, you can choose to run Tekla Structures in multi-user mode. We recommend that you only run Tekla Structures in multi-user mode if the users will make use of the additional features of multi-user mode. To run Tekla Structures in multi-user mode, one machine in the network has to be set up as a server running the Tekla Structures server program. See also

Tooltips When you move the mouse pointer over an icon, a tooltip appears. Tekla Structures contains three types of tooltips: Basic tooltips
Basic tooltips only display the name of the command. If the enhanced tooltips are switched on, the basic tooltips are not displayed.
Enhanced tooltips
Enhanced tooltips give more information about the command and how it can be executed. They also give examples, hints and tips. The enhanced tooltips are switched on by default. On the basis of the information in the enhanced tooltip you are able to decide whether the command is the one that you need for your current task. You can also open the related online help topic by clicking the More... button. To show or hide the enhanced tooltips, click Tools > Options > Enhanced Tooltips.
Menu tooltips
32
Menu tooltips provide the same functionality as the enhanced tooltips, but for menu commands. The menu tooltips are displayed in a separate window, which you can drag and drop to any position on the screen. To display the corresponding menu tooltip, move the mouse pointer over a menu command.
TEKLA STRUCTURES 15 Basics of Tekla Structures
To show or hide the menu tooltips window, click Tools > Options > Menu Tooltips.
Status bar Tekla Structures displays instructions and messages on the status bar located at the bottom of the Tekla Structures window. Follow the instructions on the status bar when you use commands. For example, when you are creating a beam, always check the status bar as Tekla Structures will prompt you on how to continue.
The status bar also displays the following information:
• • • • • •
The status of Xsnap (T), SmartSelect (S), and Drag and drop (D) The level in assembly or component hierarchy (0–9) The middle mouse button mode (Pan or Scroll) The current phase The number of selected objects and handles Error messages
To view the status bar message history, click Tools > Toolbars > Message Panel. A message panel appears at the bottom of the Tekla Structures window.

2.
Do one of the following:
• • •
Click Edit > Delete. Right-click and select Delete from the pop-up menu.. Press Delete.
1.5 Selecting 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. The number of selected objects and handles is displayed in the bottom right corner of the status bar. For example: Also dimensions and dimension lines are displayed when you select a column or a beam.
36
TEKLA STRUCTURES 15 Basics of Tekla Structures
To show or hide the dimensions, click Tools > Options > Advanced Options... > Model View, and set the variable XS_DISPLAY_DIMENSIONS_WHEN_SELECTING_OBJECTS to TRUE or FALSE.
Switching rollover highlight on or off When you move the mouse pointer over objects in rendered model views, Tekla Structures highlights the objects in yellow, so that you can easily see which objects you can select.
To switch rollover highlight on or off, do one of the following: •
Press H.
•
Click Tools > Options > Rollover Highlight.
Selection switches The selection switches are special commands that control the selection of objects. Use the selection switches to define which object types can be selected. For example, if only the Select welds switch is active, Tekla Structures only selects welds, even if you select the entire model area.
TEKLA STRUCTURES 15 Basics of Tekla Structures
37
Selection filter settings also affect which objects you can select.
Model Editor selection switches The main selection switches control whether you can select objects in a component or assembly hierarchy. These switches have the highest priority.
The other selection switches control which object types can be selected. For example, you might decide to select only bolts.
For more information on how to use each switch, see the corresponding enhanced tooltip.
Drawing Editor selection switches The selection switches control which object types can be selected. The selection switches in the Drawing Editor work in the same way as the ones in the Model Editor, but the actual switches differ. The following selection switches are available in the Drawing Editor:
For more information on how to use each switch, see the corresponding enhanced tooltip.
Selecting single objects To select a single object, do one of the following: •
To select an object, click it with the left mouse button.
•
To select an object and open its pop-up menu, click the object with the right mouse button.
You can select objects with the right mouse button only if you have switched on the following options on the Tools > Options menu:
• •
Select on Right-Click Rollover Highlight
Selecting multiple objects To select multiple objects (area selection), do one of the following: •
38
TEKLA STRUCTURES 15 Basics of Tekla Structures
Hold down the mouse button and drag the mouse from left to right to select the objects that are completely within that rectangular area.
•
Hold down the mouse button and drag the mouse from right to left to select the objects that are completely or partly within that rectangular area.
To define how area selection works, click Tools > Options > Crossing Selection. When the option is off, the dragging direction affects the selection of objects, as described above. By default, the option is off. When the option is on, all objects that fall at least partially inside the rectangular area are selected, regardless of the dragging direction.
Selecting handles To select only the handles of a part: 1.
Drag the mouse from left to right to select the part.
2.
Hold down the Alt key and drag the mouse from left to right to select the part again.

Assemblies (p. 113) Cast units (p. 122)
Selecting nested assemblies and components The active select switch defines on which level you start and toward which direction you move in the component or assembly hierarchy. The status bar shows the steps you take in the hierarchy. To select and examine nested assemblies or components:
40
1.
Hold down the Shift key.
2.
Scroll with the mouse wheel. An orange box indicates the assembly or component that you can select.
TEKLA STRUCTURES 15 Basics of Tekla Structures
Example
If the Select assemblies switch is active, you can select objects in the assembly hierarchy, starting from the assemblies on the highest level, move to their sub-assemblies, and finally select single parts, bolts, and so on.
TEKLA STRUCTURES 15 Basics of Tekla Structures
41
If the Select objects in assemblies switch is active, you start selecting from single objects and move to bigger and bigger nested assemblies. See also
Assembly hierarchy (p. 114)
Modifying the selection To modify the current selection, do any of the following:
To
Do this
Add objects to the current selection
Press the Shift key and select the objects.
Toggle the selection of an object on or off
Press the Ctrl key during the selection. Tekla Structures deselects the objects that were already selected and selects those that were previously not selected.
Interrupting object selection This section is for advanced users.
You can have Tekla Structures interrupt the object selection process if the selection takes over a defined period of time. For example, if you are working on a large model and you accidentally select all or part of the model, you can interrupt the selection if it takes over 5000 milliseconds (5 seconds) to complete. To interrupt object selection: 1.
Optional: Define the time after which Tekla Structures asks if you want to interrupt object selection. a Click Tools > Options > Advanced Options... > Modeling Properties. b
Modify the variable XS_OBJECT_SELECTION_CONFIRMATION. The default value is 5000 milliseconds.

1.6 Copying and moving objects You can copy and move objects linearly, with rotation, and with mirroring. Copying creates a new object, leaving the existing object in its original position. Moving relocates the existing object. If you copy or move objects from an assembly or cast unit, Tekla Structures copies the assembly structure as well, if possible. For example, sub-assemblies are copied as subassemblies if a parent object is found. If you copy or move reinforcements or surface treatments and want them to adapt to the part they are copied or moved to:
Limitations
• •
The reinforcement or surface treatment handles must be in part corners.
•
Circular parts must have the same cross section dimensions.
The parts between which you copy or move must have the same number of cross section corners.
Tekla Structures cannot create mirrored copies of connection properties. The Copy Special > Mirror... command does not fully mirror objects if they include connections that contain, for example, asymmetrically positioned parts.
Duplicate objects When you copy or move objects, Tekla Structures checks for duplicate objects in the location where you are about to copy or move the objects to. Tekla Structures also checks for duplicates if you create new parts in the same location as an existing part. Two objects are considered duplicates if they have the same orientation and the same size of bounding box. If duplicates are found, you can choose whether to keep or delete the duplicate objects. Use the variable XS_DUPLICATE_CHECK_LIMIT_FOR_COPY_AND_MOVE to define the maximum number of objects that can be counted as duplicates while copying or moving objects. Limitations
Tekla Structures does not check for duplicates when you copy objects using a modeling tool, such as the Array of Objects (29) component.

1.7 Snapping to positions Most Tekla Structures commands ask you to pick points to position objects in a model. Snap priority, snap switches, and snap depth all affect picking. When you move the mouse pointer over objects, Tekla Structures displays snap symbols for the available snap points. Tekla Structures also displays snap dimensions, which means you can easily create objects of a desired length.
See also
XS_DISPLAY_DIMENSIONS_WHEN_CREATING_OBJECTS
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.
50
TEKLA STRUCTURES 15 Basics of Tekla Structures
You can set the snap zone using the variable XS_PIXEL_TOLERANCE. Enter the snap zone dimension in pixels.
Snap depth The first list box on the Snapping toolbar defines the depth of each position you pick. The following options are available:
•
Plane
You can snap to positions either on the view plane or the work plane, depending on what you have selected in the second list box on the Snapping toolbar.
•
3D
You can snap to positions in the entire 3D space.
•
Auto
In perspective views, this option works like the 3D option. In non-perspective views, it works like the Plane option. See also
View planes (p. 79) Work plane (p. 70)
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. Snap switches also define the snap priority of positions. 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 the snap switches.
If there is more than one point available to snap to, press the Tab key to cycle forward through the snap points, and Shift+Tab to cycle backwards through them. Click the left mouse button to select the appropriate point.
Main snap switches The two main snap switches illustrated in the following table define whether you can snap to reference points or any other points on objects, for example part corners. These switches have the highest priority. If both these switches are off, you cannot snap to any positions, even if all the other switches are on.

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 numeric coordinates and other snapping tools, such as snap switches and orthogonal snapping. 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 green 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 dialog box to specify the distance from the last point picked. Tracking along a line
56
In the illustration below, we snapped to a grid line midpoint and tracked along the tentative line for 1000 units when creating a beam.

What is a 3D model Using Tekla Structures, you can create a real-life model of any structure. The 3D model contains all the information that is needed to manufacture and construct the structure, including:
•
Geometry and dimensions
TEKLA STRUCTURES 15 Setting up the Workspace

• • •
Profiles and cross sections Connection types Materials
The 3D model is the single source of information for drawings and other outputs, such as reports and NC data files. This ensures that the information in drawings and reports is always up to date, as they react to modifications in the model.
Creating a new model You need to create a model for each Tekla Structures project. This model contains all the information about the project. Each model is stored in its own folder in the TeklaStructuresModels folder. To create a new model: 1.
Click File > New... 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.
Define where to save the new model.

Model templates This section is for advanced users.
You can save the desired settings in a model and use that model as a template when you create new models. The location of model templates is defined by the variable XS_MODEL_TEMPLATE_DIRECTORY. For example, you can set this variable to point to the same location as the variable XS_FIRM. By default, the variable points to the folder ..\TeklaStructures\
\environments\default\model_templat es\. Any model under the defined folder will be available as a model template if the file TeklaStructuresModel.xml in the model folder contains the setting TRUE. The default value is FALSE.
Creating a model template When you create a model template, always start by creating a new empty model. This is because old models cannot be completely cleaned and they might contain quite a lot of information even if you delete all objects from the model. To create a model template: 1.
Create a new model and give it a unique name. For example, Steel framework.
2.
Add the desired profiles, custom components, and so on, in the model.
3.
Save and close the model.
4.
Move the whole model folder in the location pointed by the variable XS_MODEL_TEMPLATE_DIRECTORY.
By default, the variable points to the folder ..\TeklaStructures\\environments\default\model_te mplates\. 5.
In the new template model folder, open the TeklaStructuresModel.xml file using any standard text editor.
Do not edit the TeklaStructuresModels.xml file that is located in the TeklaStructuresModels folder or in the place pointed by the variable XS_RUNPATH.

TEKLA STRUCTURES 15 Setting up the Workspace
You can define the work area to suit particular situations, for example, to concentrate on a particular area of the model. 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. See also
Defining the work area (p. 69)
Defining the work area You can shrink and expand the work area by picking the corner points of the new work area, or size the work area to include selected parts, or all model objects. You can define the work area in a selected view, or in all visible views. To define the work area: 1.
Select a command from View > Fit Work Area. For more information on each command, see the corresponding menu tooltip.
2. See also
Define the work area by following the instructions on the status bar.

2.4 Work plane The red coordinate arrow symbol indicates the work plane, which is the local coordinate system of the model. The work plane also has its own grid, which can be used for positioning parts. Tekla Structures displays the work plane grid in dark red color. To display the work plane grid, select Work plane from the second list box on the Snapping toolbar.
The red arrow symbol shows the xy plane. The z direction follows the right-hand rule:
Most of the commands that are dependent on the coordinate system use work plane coordinates. For example creating points, part positioning, and copying always comply with the work plane coordinate system. The current work plane is model-specific, so it is the same in all views. See also
Shifting the work plane (p. 70) Changing the color of the work plane grid (p. 71)
Shifting the work plane You can shift the work plane to any position by picking points, parallel to one of the global basic planes, or on a part or view plane. When modeling sloped parts, shifting the work plane helps you to place parts accurately. For example, to model horizontal bracing and purlins in a sloped roof, you need to shift the work plane to the slope of the roof. To shift the work plane: 1.
Click View > Set Work Plane and select one of the commands. For more information on each command, see the corresponding menu tooltip.

2.5 Coordinate system The symbol with three axes (x, y, and z) represents the local coordinate system and indicates the direction of the model. It is located in the lower right corner of the model view. The coordinate symbol follows the work plane.
TEKLA STRUCTURES 15 Setting up the Workspace
71
In wire frame views, the green cube represents the global coordinate system and lies at the global point of origin.
2.6 Grids Grids are used as an aid in locating objects in a Tekla Structures model. A grid represents a three-dimensional complex of horizontal and vertical planes. The grid is shown on the view plane using dash-and-dot lines.
Grid origin is the point where the zero points of each coordinate axis intersect Grid line extensions define how far the grid lines extend in each direction Grid labels are the names of the grid lines shown in views You can make grids and grid lines act magnetically so that the objects on the grid lines follow if you move the grid line.
72
TEKLA STRUCTURES 15 Setting up the Workspace
You can have more than one grid in a model. So that you can easily locate objects in your model, we strongly advise that you create a modular grid. You can create a large-scale grid for the entire structure, and smaller grids for some detailed sections. You can also create single grid lines and attach them to an existing grid.
Grid coordinates 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 , which means 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:
• •
Define the coordinates individually. For example, 0 4000 4000. Define several grid lines with equal spacing. For example, 0 2*4000.
Both methods 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 characters in the coordinates field.
Grid 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.
When working with very large grids, always having the grid labels visible might slow down Tekla Structures. To hide the grid labels when you zoom in, use the variable XS_ADJUST_GRID_LABELS.
Creating a grid When you create a new model, Tekla Structures automatically creates a grid and a view according to the saved standard properties. You can also create grids manually. To manually create a grid: 1.
Click Modeling > Create Grid...
2.
Modify the grid properties.
3.
Optional: To bind objects to the grid lines, select the Magnetic grid plane check box.
4.
Optional: When prompted, pick a point to indicate the origin of the grid. The coordinates of the picked point appear in the Grid dialog box as X0, Y0, and Z0. If you do not pick a point, Tekla Structures positions the origin according to the values you entered for X0, Y0, and Z0.

2.7 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. There are several ways to create views in Tekla Structures. For example, you can create views:
• • • •
of the entire structure of selected parts and components of selected cast units and assemblies along the grid lines
Create a basic part view when you need to see a specific part clearly. This places the part in the center of the view.
76
TEKLA STRUCTURES 15 Setting up the Workspace
Each view has properties that define its appearance. You can change the appearance of a view after you create it. You can open the view properties dialog box for each view to view or modify the properties. You can have up to nine views on the screen at the same time. If you try to open more than nine views, Tekla Structures displays a warning. If the view does not appear, check how many views you have open.
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. You cannot rotate the model with the mouse in wire frame views.
•
Rendered Objects look more realistic because they are non-transparent and their surfaces are displayed. However, you can also choose the Wireframe or Shaded Wireframe representation option in the rendered views.
Representation options in rendered views In rendered views, you can define separately how Tekla Structures displays parts and component objects. The following options are available:
TEKLA STRUCTURES 15 Setting up the Workspace
77

In this example, component objects are displayed as Rendered. Hidden Lines
78
TEKLA STRUCTURES 15 Setting up the Workspace
Parts are not transparent, i.e. underlying parts are not visible.
Option
Description
Rendered
Part surfaces are displayed, i.e. parts are not transparent.
Show Only Selected
Selected parts are displayed. Other parts are almost completely transparent.
Example
This option is useful, for example, when viewing clash check results in a large model.
Use the shortcuts Ctrl+1...5 and Shift+1...5 to set the desired representation for parts in the model and components.
View planes Each view has a view plane on which the grids are visible and points are represented as yellow crosses. Points that are located outside the view plane are red. Basic views
Basic views are those parallel to the global basic planes (xy, xz, and zy). In basic views, two axes always define the view plane and the axes 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 the third axis. The view plane options for basic views are:
TEKLA STRUCTURES 15 Setting up the Workspace
79
Plane: XY
Plane: XZ
Plane: ZY
For basic views, you also define the distance the view plane is from the global origin in the direction of the third axis. The view plane coordinate equals this distance. Other views
For view types other than basic views, you either define the view plane and coordinate by picking points, or the points are defined automatically, depending on the creation method.
Moving a view plane You can change the view plane by moving it like any other object. When you move a view plane, Tekla Structures only uses the vector that is perpendicular to the view plane. To move the view plane:

c See also
Click Modify.
View settings (p. 244)
About 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 each view a unique name if you need to open it in later sessions. When you exit the model, Tekla Structures only saves the named views. Temporary views, which have a default name in parentheses, disappear when you close them.
In multi-user mode, it is very important to give views unique names. If several users have different views with the same name, the view settings of one user may randomly override the settings of another user.
Creating grid views Grid views are views along the grid lines. You can define how many views Tekla Structures will create, how it will name the views, and which view properties it will use. Before you start, create a view that contains a grid. To create grid views: 1.

For more information on how to move part and component basic views and zoom windows across the entire Windows desktop, see XS_MDIVIEWPARENT, XS_MDIZOOMPARENT, and XS_MDIBASICVIEWPARENT.
2.8 Construction objects Construction planes, lines, and circles help you place other objects. For example, you can easily pick the points at intersections of construction lines and circles. The snap priority of construction objects is the same as with the other lines. Construction objects remain in the model when you update or redraw views and windows. They do not appear in drawings. You can also create magnetic construction lines or planes to bind and move groups of objects. For example, rather than binding lots of handles and chamfers to faces, simply create a construction plane that goes through all the handles and chamfers. Then make this plane magnetic and bind the plane to the appropriate face. When you move the plane, the attached handles and chamfers move with it.

2.9 Points You can create points to make it easier to place objects at positions where no lines or objects intersect. 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 on the view plane are yellow and points outside the view plane are red.
TEKLA STRUCTURES 15 Setting up the Workspace
85
Point properties The point information you are most probably interested in is the local (work plane) and global x, y, and z coordinates of a point. Checking them convinces you of the correct location of the point or some other object related to it. Each point also has a phase number, and an ID number that is used in log files. You can filter objects by their phase and ID numbers.
Creating a point To create a point: 1.

Importing points This section is for advanced users.
You can import points to specific locations in an open Tekla Structures model using the point creation import macro. You need to specify the point coordinates in a text file. In some cases this file is generated by another software package. To import points from a file: 1.
Create a point import file. a Create a text file that consists of single lines for each point. Use commas or tabs as delimiters for the three point coordinates on a line. For example: 100,500,1000 300,700,1500

During the import process, Tekla Structures ignores all lines in the import file which do not consist of valid values delimited by tabs or commas.
2.10 Reference models A reference model is a file which helps you to build a Tekla Structures model. A reference model is created in Tekla Structures or another software or modeling tool and imported to Tekla Structures. For example, an architectural model, a plant design model, or a heating, ventilating and airconditioning (HVAC) model can be used as a reference model. Reference models can also be simple 2D drawings that are imported and then used as a layout to directly build the model on. The following file types are supported:
• • • • • •
AutoCAD (*.dxf) AutoCAD (*.dwg) MicroStation (*.dgn, *.prp) Cadmatic models (*.3dd) IFC files (*.IFC) Tekla WebViewer XML files (*.xml)
You can snap to reference model geometry. Tekla Structures loads the reference model from the file each time you open your model. It does not save the reference model when you save the current model. The filename extension of a saved reference model properties file is *.rop.
Inserting a reference model To insert a reference model in a Tekla Structures model: 1.

3.1 Parts In Tekla Structures, the term part refers to the basic building objects that can be modeled and detailed further. These are the building blocks of the physical model. Every part has properties that define it, such as material, profile, and location. You can use part properties in view and selection filters. For example, you can select, modify, and hide parts based on their properties. You can also include part properties and user-defined attributes in drawing and report templates. Each part has the following properties:
Property
Description
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.
Profile
See Profiles (p. 96).
Material
See Materials (p. 98).
TEKLA STRUCTURES 15 Creating and Modifying Structures

Property
Description
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. For example, you can display parts of different classes in different colors.
Part types The main concrete parts are:
• • • • • • •
beam polybeam column pad footing strip footing panel slab
The main steel parts are:
• • • • • • •
beam curved beam orthogonal beam polybeam column twin profile contour plate
Profiles Tekla Structures contains standard, parametric, and user-defined profiles. When you create or modify a part, you can select the profile from a tree that contains all the profiles available in the profile catalog. The profiles are grouped according to rules that you can define and modify. For user-defined profiles Tekla Structures also displays cross section information.
Icon
Description A standard profile. A parametric profile.
For more information on how to modify the profile catalog and rules, and how to associate profile types with materials, see The profile catalog and Working with rules. See also
96
Standard profiles (p. 97)
TEKLA STRUCTURES 15 Creating and Modifying Structures
Parametric profiles (p. 97) User-defined profiles (p. 97)
Standard profiles When you first start Tekla Structures, the profile catalog contains standard, environmentspecific profiles. The properties of these library profiles conform to industry standards, so you should not edit them. You can add profiles to the profile catalog.
Parametric profiles You can use parametric profiles to model profiles that are standard in a specific environment, but do not exist in the Tekla Structures profile catalog. Parametric profiles are partly userdefinable and they have a predefined shape, but you determine their size by giving one or more parameters. Parametric profile names have specific prefixes and they include dimension values. Dimension values in parametric profile names are separated by the standard separators -, X, /, and *. You can define alternative prefixes for parametric profiles. You can also define additional separators using the variables XS_PARAMETRIC_PROFILE_SEPARATOR and XS_USER_DEFINED_PARAMETRIC_PROFILE_SEPARATORS .
User-defined profiles You can create your own profiles and save them in the profile catalog. For example, you could create a pitched user-defined profile, with different cross sections at the beginning and end of the profile. For more information on creating your own profiles, see Sketched cross sections (p. 215) and Adding a standard (fixed) user-defined profile.

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 that should always be under tension.
Camber
In part marks in Tekla Structures drawings.
Preliminary mark
To obtain preliminary marks for parts in reports.
Locked
To protect objects from being accidentally changed.
Shear, Tension, and Moment
To save reaction forces for AutoDefaults. You can enter forces separately for each end of a part.
User field 1...4
User-defined fields. You can change the names of these fields and add new user-defined fields.
Connection code

3.2 Part position When you create a part, you position it by picking points. The points form the part reference line. You can use part reference lines to help snap to the middle points of parts, for example. Tekla Structures indicates the direction of a part with handles. When you select a part, Tekla Structures highlights the handles. The handle of the first end point is yellow, the rest are magenta.
The handles also symbolize the part reference points. The position of a part is always relative to its reference points. See also

Example
In this example, the concrete columns form a two-story structure. To position the upper columns correctly, you must modify their bottom level position.
Top level = 1000, Bottom level = 0 Top level = 1700, Bottom level = 1200 Slab thickness = 200
Bending You can create curved parts by defining a radius and the plane of curvature. When you initiate a command that creates a curved part, for example a curved beam, Tekla Structures prompts you to pick three points to define the radius. Alternatively, you can define the radius in the part properties dialog box. To have Tekla Structures draw a curved part, you need to specify the 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.
The number of segments affects the speed of many operations, such as numbering and the creation of drawings.
You can also define the plane of curvature, which is relative to the current work plane. The options are:
• •

3.4 Assemblies Tekla Structures creates basic assemblies of steel parts when you use a workshop weld or bolt to join parts together. 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.
You can also create nested assemblies by adding sub-assemblies to existing assemblies, or by joining assemblies together. The main part in a steel assembly has other parts welded or bolted to it. By default, the main part is not welded or bolted to any other parts. You can change the main part in an assembly. See also
Selecting nested assemblies and components (p. 40)
Assembly examples Column corbel
A column corbel is fabricated in one workshop, and then attached to the column in another workshop. Model the corbel as a sub-assembly of the column. Then create an assembly drawing for each workshop: one assembly drawing showing how the corbel is welded together, another assembly drawing showing how the corbel and the other part are welded to the column.
TEKLA STRUCTURES 15 Creating and Modifying Structures
113
Drawing 2, Workshop 2 Drawing 1, Workshop 1 Complex truss
Model the halves of a complex truss as assemblies. Create assembly drawings for the workshop to fabricate the truss halves. Then create another assembly drawing showing how the halves should be joined on site.
Built-up profile
In a frame of built-up columns and beams, each built-up profile can be a sub-assembly. You can create an assembly drawing showing the entire frame, and separate drawings showing how the columns and beams are constructed.
Assembly hierarchy You can work on any level of a nested assembly, from single parts and bolts, through the basic and sub-assemblies, up to the highest level of the nested assembly. To work with nested assemblies, you need to know how to use the Shift key and mouse scrolling to select objects on different levels in assembly hierarchy.
114
TEKLA STRUCTURES 15 Creating and Modifying Structures
Assembly hierarchy in nested assemblies affects drawings and reports. You can create separate drawings and reports of the sub-assemblies and the nested assembly, and still produce dimensions, marks, fabrication information, etc. for all assembly levels. See also

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

4.1 Bolts To create bolts, you can either create a single bolt group or apply a component that automatically creates bolt groups.
For more information on using components to automatically create bolt groups, see Defining bolts and welds in the Detailing Manual.
TEKLA STRUCTURES 15 Detailing Structures
127
You can create different part marks for holes and bolts in drawings. You cannot use bolt elements (such as screws, washers, and nuts) while creating holes, as Tekla Structures uses the same command for creating bolts and holes.
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 of the Bolt dist X and Bolt dist Y fields to determine how many bolts the bolt group contains, as shown in the table below:
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.
Bolt group position Tekla Structures determines the location of the bolt group using the following values:
• •
Bolt group x axis Work plane
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. It is important that the points you pick to create the bolt group are close enough to the parts you want to connect. Examples
128
The picked points are shown as crosses in the examples below. The dashed line indicates the x direction.

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 Properties dialog box affect bolt length calculation:
TEKLA STRUCTURES 15 Detailing Structures
129
Field
Description
Thread in material
Indicates if the thread of the bolt can be inside the bolted parts. Tekla Structures does not use this value when calculating the length of full-threaded bolts.
Cut length
Indicates the area Tekla Structures should search for parts that belong to the bolt group. Using cut length you can determine whether the bolt will go through one flange or two. In the illustration below, A is the cut length and B is the bolt origin. Tekla Structures calculates the search area as A/2 in both directions from point B.
Tekla Structures warns you if the cut length is too small (i.e. the bolt group contains no parts) and makes the bolt length 100 mm. Extra length
Increases the material thickness that 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 you want to force a bolt to be a certain length, enter a negative value for cut length (e.g. -150).
If there are large gaps between the 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 offsets You can use offsets to change the position of the bolt group. Offsets move the bolt group by moving the x axis of the bolt group.
130
TEKLA STRUCTURES 15 Detailing Structures
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 bolt group:
The bolts were created using the following bolt properties:
• • • • • • •
Shape = Array Bolt dist X = 100 100 Bolt dist Y = 200 Slotted hole X = 28 Bolt size = 20 Tolerance = 2 (overall dimension = 50) Dx Start point = 100.0
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.

4.3 Welds To create welds in Tekla Structures, you can create single welds, or apply components that automatically create 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.
TEKLA STRUCTURES 15 Detailing Structures
135
If you move welded parts, polygon welds move with the primary part.
•
Single part welds
Weld position You define the position of a weld relative to the work plane. The type and position of the parts to be welded affect the position of the weld. The options for weld position are:
• • •
x y z
These can all be in a positive or negative direction. Tekla Structures creates the weld on the face or side of the part that faces in the selected direction (x, y, or z). Examples
136
The following images show welds in different positions. If there are no faces that touch in the specified direction, Tekla Structures places the weld relative to the center point of the secondary part.

Weld preparation When parts are prepared for welding, their edges can be beveled to produce a groove for the weld. You can define the angle of bevels and grooves. When preparing welds, Tekla Structures bevels the parts to be welded using an anti-material cutting part. Tekla Structures subsequently deletes this cutting part. Tekla Structures displays weld preparations using cyan dash-and-dot lines. Some weld types and connections also automatically prepare the parts to be welded.

Using welds to create assemblies Tekla Structures forms assemblies based on where the weld should be made. You can create workshop welds and site welds. The order in which you select parts when creating the connection determines the main and secondary parts of the assembly or the assembly hierarchy. The first part you select becomes the primary part of the assembly. Tekla Structures dimensions secondary parts relative to the primary part in assembly drawings. The largest primary part in the weld becomes the main part of the assembly. When you connect assemblies, the first part you select determines the assembly to which you weld sub-assemblies. To control how Tekla Structures creates assemblies, use the Connect part/assembly and Workshop/Site list boxes in the Weld Properties dialog box.

4.4 Surface treatment Use the surface treatment tools to add surface treatment to parts. Surface treatment for concrete parts include flat finishes, surface mixes, and tiles. Surface treatment for steel parts include fire-proofing and unpainted areas, for example. Surface treatments are visible only in rendered views. When you redefine the properties of a part (e.g. you change the size of a part), Tekla Structures automatically modifies the surface treatment to fit the part.
When you create overlapping surface treatments, the smaller surface treatment overrides the larger one. The overlapping area is recognized in reports: only the topmost (visible) surface treatment is calculated.

If you are using the To Selected Area on Part Face command, pick the points to define the area of the surface treatment.
Surface treatment on chamfered parts Take these things into account when adding surface treatment to chamfered parts:
• •
Surface treatment does not work on sketched profiles with chamfers.
•
The chamfers for the main part and surface treatment are separate. Modifying the main part chamfer does not affect the surface treatment chamfer.
•
The orientation of unsymmetric chamfers depends on the face where it was created (such as top, bottom, left, or right). To change the orientation of an unsymmetric chamfer, you must swap the chamfer's x and y values.
Add surface treatment before chamfering the part. If surface treatment is applied to a chamfered part, the surface treatment chamfer cannot be modified later on.
Surface treatment on parts with openings and recesses To force Tekla Structures to consider openings and recesses in parts when adding surface treatment, select the Cut by father part cuts checkbox in the Surface Treatment Properties dialog box.

4.5 Fine-tuning part shape This section describes the various tools you can use to fine-tune the shape of a part. See also
Creating and Modifying Structures (p. 95)
Chamfers Chamfers are modeling details that can be used to refine the shape of parts for aesthetic, practical, and manufacturing reasons. In Tekla Structures, you can chamfer part corners and part edges. Limitations
Only the following parts have corner chamfers: contour plates, concrete slabs, and parts that you create by picking more than two points (strip footings, steel and concrete polybeams, and concrete panels). The end points of a part do not have corner chamfers. The handles that you select must be at corner points or between two segments of a part.
TEKLA STRUCTURES 15 Detailing Structures
149
Chamfering part corners 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. You can modify the default chamfers.
To modify a corner chamfer: 1.
Select the part.
2.
Double-click the handle of any part corner. The Chamfer Properties dialog box is displayed.

To see the chamfer lines of polybeams, set the variable XS_DRAW_CHAMFERS_HANDLES to CHAMFERS.
Fittings You can fit the end of a part to a plane by creating a straight cutting line between two points you pick. You can use fittings to extend or shorten parts inside a component, which makes it easier to create connections, details, and so on. Do not use fittings to otherwise change the length of a part in the model. A fitting 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. Fittings cannot be used on contour plates.
Fitting symbol
Creating a fitting To create a fitting: 1.
Click Detailing > Fit Part End.
2.
Select the part you want to cut with a fitting.
3.
Pick the first point of the cutting line.
4.
Pick the second point of the cutting line.
Do not apply a second fitting on the same part end, because then Tekla Structures will ignore the first fitting. This happens if you use the Fit Part End command for cutting and try to make two cuts on the same part end. In situations like this, use the Cut Part commands instead.
TEKLA STRUCTURES 15 Detailing Structures
153
Cuts You can use cuts to shape a part. Do not use cuts for cutting the entire part end. You can create the following types of cuts in Tekla Structures:
• • •
Line cuts (p. 154) Polygon cuts (p. 155) Part cuts (p. 156)
Line cuts A line cut cuts the end of a beam on a plane, perpendicular to the view plane, which passes through the cutting line you pick. Tekla Structures displays the cut in the model using a blue cut symbol.
Exact representation (without cut symbol) Fast representation (with cut symbol) By default, line cuts do not affect beam length in NC files. For more information on how to change this, see Fittings affect NC data.
Cutting parts with a line Use line cuts to shape the end of a beam or column. To cut a part with a line:
154
1.
Click Detailing > Cut Part > With Line.
2.
Select the part you want to cut.
3.
Pick the first point of the cutting line.
4.
Pick the second point of the cutting line.
5.
Pick the side you want to remove.
TEKLA STRUCTURES 15 Detailing Structures
Polygon cuts A polygon cut cuts a part using a polygonal shape. Tekla Structures displays the cut using dotdash lines. You must create cuts in a plane view.
Exact representation (without symbol) Fast representation Polygon-shaped cut
You should always define the polygon so that there is some tolerance between the edges. If the edge of a cutting polygon is in exactly the same position as the edge of the part to be cut, it can be unclear whether the edge should be cut away.
Cutting parts with a polygon To cut a part using a polygonal shape: 1.
Ensure that the work plane is on the plane you are cutting on.
TEKLA STRUCTURES 15 Detailing Structures
155
For example, if you are creating a polygonal cut on the yz plane, you should temporarily set your work plane to the yz plane as well. 2.

Cambering parts You can use cambering to pre-camber parts, in other words, to curve long heavy sections that will settle on site and become flat. Use cambering to show the natural camber of a prestressed part in a model. Cambering affects the position of cuts, skews, and embeds in the model. Tekla Structures cambers parts in the local z direction.
TEKLA STRUCTURES 15 Detailing Structures
161
The cambering functionality is available only in the Full and Precast Concrete Detailing configurations.
Cambering a part To camber a part: 1.
Double-click the part to open the part properties dialog box.
2.
Go to the Deforming tab.
3.
In the Cambering field, define the degree of camber.
4.
Click Modify.
Shortening parts in drawings Use the shortening functionality to make the drawing of a part longer or shorter than the part in the model. This can be useful for adding length to concrete precast parts in the cast condition while the model stays in the erected state. The most common use for this is to account for prestressing elastic shortening, where the part actually shrinks a fraction of an inch after casting and after the strands are cut. When drawings are created, Tekla Structures decreases the true length of the part by the value defined in the Shortening field. Shortening is applied linearly along the length in drawings. Shortening affects the dimensions of the part and dimensions to objects inside the part. Shortening does not affect the geometry of the actual objects inside the part, including the template output.
The shortening functionality is available only in the Full and Precast Concrete Detailing configurations.
Shortening a part To shorten a part in drawings: 1.
Double-click the part to open the part properties dialog box.
2.

5.3 Filtering objects Use filtering when you want to perform an operation on several objects or properties at the same time. Filters are particularly useful for complicated models that contain a large number of objects. You can create two types of filters: view filters and selection filters. Tekla Structures contains several standard filters you can use. Example
Create a selection filter for a rule set in the Master Drawing Catalog to automatically create drawings of desired objects. For example, if you only want to produce drawings of the beams in the model, use a selection filter to select the beams.
TEKLA STRUCTURES 15 Examining the Model

In the Value list box, enter the ID numbers of the reference models you want to hide. To hide several reference models, separate their IDs with spaces.
6.
Enter a unique name in the field next to the Save as button.
7.
Click Save as.
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:
176
TEKLA STRUCTURES 15 Examining the Model
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
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. For example, to find the profile P100*10, enter P100[*]10 in the filter field.
Possible values in filtering You can create filters that contain several properties. You can also have multiple filtering values for each property. If you use multiple values, separate the strings with blank spaces (for example, 12 5). If a value consists of multiple strings, enclose the entire value in quotation marks (for example, "custom panel"). By using conditions, parentheses, and the And/Or option you can create filters that can be as complex as needed.
When you create rules between objects that represent different categories, use the And option when possible to avoid potential problems with more complex rules.
Empty values are matched to empty properties in filtering.
Template attributes in filtering This section is for advanced users.
TEKLA STRUCTURES 15 Examining the Model
177
You can select objects according to template attributes. To do this, select Template from the Category list box, and then select the desired template attribute from the Property list box. Use the following units when filtering template attributes, even when using the US Imperial environment:
• • • •
mm for length mm2 for area kg for weight degree for angle
To check which unit Tekla Structures uses for a particular template attribute, use the Select from model... option in the Value list box.
Assembly types in filtering If the category you have selected is Assembly, the property you have selected is Assembly type, and you select the option Select from model... in the Value list box, Tekla Structures returns the value as a number. The number indicates the type of assembly in question. The following table lists the numbers and the corresponding assembly types:
Value
Assembly type
0
precast
1
cast in place
2
steel
3
timber
6
miscellaneous
Bolts and welds in filtering Tekla Structures follows these principles when filtering bolts or welds:
•
If the category you have selected is Bolt or Weld, Tekla Structures uses the phase number of the actual bolt or weld in filtering.
•
If the category you have selected is Assembly or Object, Tekla Structures also uses the phase number of the secondary part for filtering bolts and welds.
•
If the bolt or weld is connected only to one part, Tekla Structures uses the phase of that part in filtering.

Numbering the Model
This section explains how to change numbering settings and apply numbering in Tekla Structures. Contents

What is numbering (p. 195) What affects numbering (p. 195) Numbering objects (p. 197) Numbering series (p. 201) Changing numbers (p. 204) Clearing numbers (p. 204) Viewing the numbering history (p. 204) Creating a standard part model (p. 205)
6.1 What is 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 before you can create single-part, assembly, cast unit, and multi-drawings, or export files from a model. Tekla Structures uses part numbers in many tasks, for example to:
• • •
connect a drawing with the right part, cast unit, or assembly report the properties of identical parts, cast units, and assemblies identify part information when exporting parts to another software.
6.2 What affects numbering Tekla Structures treats objects as different, and therefore numbers them differently, if the following properties differ:
TEKLA STRUCTURES 15 Numbering the Model
195
• • • • • • • •
Beam orientation Column orientation Reinforcement Cast-in embeds Surface treatment (affects only assemblies) Pop marks Shortening User-defined attributes
To define which properties affect numbering in your model, modify the settings in the Numbering Setup dialog box. For example, if two otherwise identical concrete parts have different names and you select the Part name check box, Tekla Structures gives the parts
different numbers. 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.
Identical parts Tekla Structures gives parts the same number if the parts are identical in the fabrication or casting. If a part is deformed after fabrication or casting (for example if the part is cambered, shortened, or warped), the final geometry on site and in the model may be different. Tekla Structures treats parts as identical and gives them the same number if the following basic part properties are the same:
• • • • •
Part geometry Numbering series Profile Material Finish
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. Class and phase do not affect numbering. Tekla Structures gives the same number to identical parts that belong to different classes or phases.
Identical reinforcements Tekla Structures treats reinforcing bars as identical, and gives them the same number, if the following properties are the same:
• • • • •
196
TEKLA STRUCTURES 15 Numbering the Model
Bar geometry Numbering series Size Grade Bending radius
Tekla Structures uses the values of the rebar_config.inp file located in the ..\environments\\system\ folder to round bar dimensions up or down. For example, if you set the rounding accuracy for bar dimensions to 5 and the rounding direction to up, Tekla Structures rounds all bar dimensions up to the nearest 5 mm. In that case, two bars with dimensions of 131 mm and 133 mm would both round up to 135 mm. This gives them identical bar geometry. Class does not affect numbering. Tekla Structures gives the same number to identical reinforcing bars that belong to different classes.
User-defined attributes in numbering Tekla Structures treats parts and reinforcing bars as different, and therefore numbers them differently, if the values of a user-defined attribute differ. Parts
If a user-defined attribute has the variable special_flag set to yes, Tekla Structures takes this user-defined attribute into account when numbering parts.
Reinforcements
If a user-defined attribute has the variable consider_in_numbering set to yes, Tekla Structures takes this user-defined attribute into account when numbering reinforcements.
6.3 Numbering objects Tekla Structures keeps a list of objects that have been modified or created since numbering was last carried out. When you number the model, you can choose whether you want to number all the objects or only the new and modified objects.
Always carry out full numbering on the model after you have changed the numbering settings.
To number objects in a model: 1.
2.
Optional: Modify the numbering settings. a Click Drawings & Reports > Numbering > Numbering Settings... to open the Numbering Setup dialog box. b
Modify the settings.
c
Click Apply or OK.
Click Drawings & Reports > Numbering and select one of the commands.
• • •
To number all the objects, select Number All Objects (Full Numbering). To number only the new and modified objects, select Number Modified Objects. To number the welds, select Number Welds...
If the Renumber all option is selected in the Numbering Setup dialog box, Tekla Structures will always carry out full renumbering.

General numbering settings (p. 259) Weld numbering settings (p. 260)
Numbering assemblies and cast units Part numbering does not affect cast unit and assembly numbering. However, Tekla Structures numbers assemblies and cast units in the same way as it does parts. The default starting number is 1. The prefix varies based on the part type. Surface treatments affect the numbering of assemblies, if you select the Surface treatment check box in the Numbering Setup dialog box.
Assembly and cast unit numbering may affect part numbering, if the variable XS_USE_ASSEMBLY_NUMBER_FOR is set.
Assembly position numbers Use the options in the Numbering Setup dialog box to sort the order in which assemblies are given their position numbers. Sorting by user-defined attributes or by location does not affect the part position. The sort order can be based on the following criteria:
•
The x, y or z coordinates of the main part of the assembly The sorting is based on the center of gravity of the reference axis.
•
The user-defined attribute of an assembly or the main part If your sorting is based on user-defined attributes, Tekla Structures displays a list box that includes all the available user-defined attributes.
If you add new parts, objects that have already been numbered are not renumbered to suit the sorting order by, for example, the x coordinate. In this case you should renumber the parts.
Numbering reinforcements Part numbering and cast unit numbering do not affect the numbering of reinforcements. However, Tekla Structures numbers reinforcements in the same way as it does parts. To force Tekla Structures to give otherwise identical concrete parts and cast units different numbers if they have different reinforcements, select the Reinforcing bars check box in the Numbering Setup dialog box.
Saving preliminary numbers A preliminary mark is a user-defined attribute that defines the part position number. You can save the current part position numbers as preliminary marks for selected parts. The previous preliminary numbers are overriden. To save part position numbers for preliminary marks:
198
TEKLA STRUCTURES 15 Numbering the Model
1.
Select the parts.
2.
Click Drawings & Reports > Numbering > Save Preliminary Numbers.
Control numbers Control numbers are properties that identify the location of parts in a model. You can assign consecutive control numbers to all the parts or only selected parts. When you assign control numbers, you can specify in what order to assign control numbers, according to the location of each part on the global coordinate system. The options are:
• • • • • • •
None X -X Z -Z Y -Y
With positive directions (such as X), the parts with the lowest coordinate value are numbered first. With negative directions (such as -X), the parts with the highest coordinate value are numbered first. For example, if First direction is -X, Second direction is Y, and Third direction is Z, numbering starts from the parts that have the highest x coordinate value. If multiple parts have the same x coordinate, their y coordinates are also compared. If multiple parts have the same x and y coordinates, their z coordinates are also compared. Example
In the following example, the sort order is X Y Z.
Assigning control numbers to parts Before you start, number the model. To assign control numbers to parts: 1.
Click Drawings & Reports > Numbering > Assign Control Numbers... to open the Create control numbers dialog box.
2.
Indicate which parts to consider.
• • 3.
To consider all parts in the model, do not select any parts. To only consider specific parts, select the parts.
In the Numbering list box, specify which parts get control numbers.

Example: Numbering identical beams This example explains how different numbering settings result in different part numbers when you modify a part. To number identical beams: 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. Depending on the numbering settings in the Numbering Setup dialog box, Tekla Structures assigns one of the following part position numbers to the modified part:
• • •
200
TEKLA STRUCTURES 15 Numbering the Model
Compare to old: P1 Keep number if possible: P2 Take new number: P3
6.4 Numbering series You can use a numbering series to divide steel parts, cast units, and assemblies into groups. For example, you can allocate a separate numbering series to different phases or part types. The name of a numbering series consists of a prefix and a starting number. By default, the steel part mark prefix is P, the concrete part prefix is C, and the starting number is 1. You do not have to specify a part prefix (for example, you may want to omit the part prefix for minor parts). When you run numbering, 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. 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, ...
Assigning a numbering series to a part You can assign a numbering series to any part or assembly. To assign a numbering series to a part: 1.
Double-click the part to open the part properties dialog box.
2.
If you are modifying the properties of a concrete part, go to the Cast unit tab.
3.
Under Numbering series, define a part prefix and a starting number.
4.
Click Modify.
Family numbers With family numbering you can group objects within the same numbering series into different “families”. This can be used, for example, to find similar cast units that can be cast in the same bed. When you use family numbering, the cast unit position numbers consist of a family number and a qualifier. For example:
Family number Qualifier Assemblies and cast units that match the comparison criteria you define in the Numbering Setup dialog box get the same family number. However, if they have the same family number but different part geometry or materials, they get unique qualifier numbers.
Assigning family numbers To assign family numbers to numbering series:
TEKLA STRUCTURES 15 Numbering the Model
201
1.
Click Drawings & Reports > Numbering > Numbering Settings... to open the Numbering Setup dialog box.
2.
Go to the Family numbering tab.
3.
Define which numbering series to assign family numbers to. a Click Add series to open the Add series dialog box. Tekla Structures displays all the assembly and cast unit numbering series in the model. b
Select a numbering series from the list, and then click Add. The numbering series appears in the family numbering list.
4.
Under Compare, select the properties that need to be identical for the members of the same family. Define comparison criteria for each numbering series separately. Select at least one check box, but not all of them. If you select all the check boxes, the family number will be the same as the normal assembly position, and the qualifier number will be 1 for all. If you do not select any check boxes, only one family number per series is assigned.
5.
Click Apply. Tekla Structures stores the settings in the numbering database file (.db2) in the current model folder the next time you save the model.
6.
If you are assigning family numbers to parts that have already been numbered, clear the existing numbers.
7.
Update numbering in the model. Tekla Structures assigns a family number to all objects in the numbering series.

Clearing numbers (p. 204)
Changing the family number of an object To change the family number and/or family qualifier of an object: 1.
Select the objects whose family numbers you want to change.
2.
Click Drawings & Reports > Numbering > Change Number > Family Number...
3.
In the Assign Family Number dialog box, type the desired values in the Family number and Family qualifier fields.
4.
Click Assign.
Family numbering example In this example, the following four beams have the numbering series prefix B and the start number 1. The parts have the same main profile, and each pair has the same length, but the holes are different.
202
TEKLA STRUCTURES 15 Numbering the Model
Assembly position: B/1 Assembly position: B/2 Assembly position: B/3 Assembly position: B/4 We use the following family numbering settings:
• •
Numbering series: B/1 Compare: Main part profile and Overall length
With the given family numbering criteria, Tekla Structures divides the beams into two families. All beams have the same profile, but each pair has a different length. Within both families the beams get different qualifiers because they have different holes.
• • • •
The first beam gets the assembly position number B/1-1 The second beam gets the assembly position number B/1-2 The third beam gets the assembly position number B/2-1 The fourth beam gets the assembly position number B/2-2
Overlapping numbering series When you plan numbering, ensure that you reserve enough numbers for each series. If a series overlaps 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.
TEKLA STRUCTURES 15 Numbering the Model
203
6.5 Changing numbers Use the Change Number command to change part, assembly, multi-position, or family numbers after you run numbering. All objects with the same number will be given the number you specified. This command does not change the numbering series. To change the position numbers: 1.
Select an object.
2.
Click Drawings & Reports > Numbering > Change Number and select one of the commands. For more information on each command, see the corresponding menu tooltip.
3.
Set the desired properties. The options you have vary depending on your selection in step 2. If the number you specified is already in use, Tekla Structures displays a warning and does not change the number.Tekla Structures also displays a warning if the position number is higher than the highest current number. This is for information only and the number is still changed.
4.
Click Assign.
6.6 Clearing numbers Use the Clear Numbers command to permanently delete the assigned position numbers of objects. Next time you run numbering, Tekla Structures assigns new numbers to the objects, irrespective of what their previous numbers were. To clear the position numbers: 1.
Select the objects whose numbers you want to clear.
2.
Click Drawings & Reports > Numbering > Clear Numbers and select one of the commands. For more information on each command, see the corresponding menu tooltip.

204
TEKLA STRUCTURES 15 Numbering the Model
6.8 Creating a standard part model A standard part model contains only standard parts with specific part prefixes. You can have Tekla Structures use these prefixes when numbering parts in another model. To create a standard part model: 1.
Create a new model and give it a descriptive name. For example, StandardParts.
2.
Create the objects you want to have as standard parts.
3.
Explode all components.
4.
Delete all unnecessary items.
5.
Give the objects prefixes that are not used elsewhere (for example, STD1, STD2, and so on). Ensure that the standard part model does not contain duplicate prefixes.
6.
Save the standard part model.
7.
Open another model.
8.
Click Tools > Options > Advanced Options... > Numbering.
9.
Check that the variable XS_STD_PART_MODEL is set, and that it points to the correct standard part model. For example: XS_STD_PART_MODEL=C:\Tekla StructuresModels\StandardParts
10.
Click Drawings & Reports > Numbering > Numbering Settings... to display the Numbering Setup dialog box.
11.
If you have selected the Part name check box, ensure that the project model has the same part names as the standard part model.
12.
Click Check for standard parts and Apply.
13.
Number the model. As Tekla Structures carries out the numbering, it compares all of the parts in the model to the standard part model. The numbering applies any part position numbers (only the part prefix) found in the standard part model to all identical parts found in the project model.

7.2 Phases Use phases to break up a model into 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. For example, you might have a large project which several users work on simultaneously in single-user mode. First create a basic model that 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. When a part of the model is completed, you can copy it back to the basic model as a separate phase (phase 2, 3, etc.).
Dividing the model into phases To divide a model into phases: 1.
Click Tools > Phase Manager.... The Phase Manager dialog box appears.
2.
Click Add to create new phases.
3.
Click Set current to make the selected phase the current phase. From now on, Tekla Structures assigns all objects you create to the current phase. The @ character in front of the phase number indicates the current phase.
4.
Divide the model into phases. a To identify the phase of an object, select an object and click Phases by objects. Tekla Structures selects the phase of the object. b
To see which objects belong to a certain phase, select a phase from the list and then click Objects by phases. Tekla Structures highlights the corresponding objects in the model.
c 5.
To change the phase of one or more objects, select the objects, select a phase from the list, and then click Modify phase.
Click OK to save your changes.
Custom phase properties You can add custom phase properties, which will appear as extra columns in the Phase Manager dialog box.
Define the names of phase properties in the objects.inp file. To use phase properties in reports and templates, use the syntax PHASE.ATTRIBUTE_NAME in the phase property field name.
7.3 Sequences Use the Sequencer tool to name sequences and assign incremental numbers to parts. For example, you can define the order in which to erect parts by creating erection sequences. You can define several sequences for different purposes, and a part can belong to several sequences at the same time.
TEKLA STRUCTURES 15 Advanced Modeling
211
Sequencer works by assigning a sequence number to a user-defined attribute of a part. The sequence name that you enter in the Sequencer Properties dialog box is the name of the userdefined attribute defined in the objects.inp file. Limitations
Sequencer does not work for objects that are inside a reference model.
See also
Lotting (p. 214)
Creating a sequence Use the Sequencer tool to assign sequence numbers to parts. If you want to view and modify the sequence number afterwards, you must first create a user-defined attribute to which you assign sequence numbers. To create a new sequence: 1.
Create a user-defined attribute to which you assign sequence numbers. a Open the objects.inp file in any standard text editor. b
In the Part attributes section, add a new user-defined attribute. The value_type must be integer, and the field_format must be %d. For example: attribute("MY_INFO_1", "My Info 1", integer, "%d", no, none, "0.0", "0.0")
c
Save the file.
d
Restart Tekla Structures.
2.
Click Tools > Sequencer to display the Sequencer Properties dialog box.
3.
Type a name for the sequence. Use exactly the same name as in the objects.inp file. For example, MY_INFO_1.
4.
Click Apply.
5.
Select the parts you want to include in the sequence. The first part gets the sequence number 1, the second part number 2, and so on. If you select a part that has already been included in the sequence, Tekla Structures asks if you want to override the existing number. If you click Yes, Tekla Structures gives the next available number to the part.
6.
To finish adding parts to the sequence, click Edit > Interrupt or press Esc.

7.4 Lotting With lots you can group assemblies for transporting to site. Lotting means that you evaluate specific model parts with respect to the number of units that can be carried by a transfer vehicle. For example, you can calculate how many concrete truck deliveries are needed to pour the footings or slabs for a specific portion of the model. With this information, it is easier to determine area requirements and create an erection schedule. When you define lots, you must take into account the load-carrying capacity of the vehicle, because a lot cannot exceed the maximum total load capacity. You can calculate truck load sizes based on material weights and model quantities. For most model parts, the weight is based on the size, length, and material of the part.
To view the properties of a part, right-click the part and then select Inquire > Part or Properties...
You can use lotting in conjunction with the Sequencer tool. For example, you can load each part of the model onto a specific truck based on the erection sequence of the part. The basic lotting process is the same for steel and concrete parts. However, if you are using cast-in-place concrete, remember that the concrete is transported in a volumetric container (for example, in a ten-cubic-yard truck). In that case, you must calculate the weight-carrying capacity of the concrete vehicle before defining the number of lots. See also

Defining positioning planes of sketched cross sections When you sketch a cross section, you can define positioning planes for it. This means you can determine the planes Tekla Structures will use when it positions parts. These planes are used also when placing custom components that are bound to boundary planes. By default, the positioning planes are placed according to the bounding box of the part. See also
Part positioning planes (p. 222) Connection positioning planes (p. 222) Part position (p. 101)
Part positioning planes With part positioning planes you can determine how Tekla Structures positions parts which have a sketched profile cross section. Example
You can define part positioning planes that define the Middle option of an asymmetric cross section:

7.6 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.
TEKLA STRUCTURES 15 Advanced Modeling
233
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. The Modeling menu includes the following parametric modeling tools:
Command
Icon
Add Distance > Fixed
Description Binds a handle on a model object to up to three planes on other model objects, at a fixed distance. Illustrates the distance in the model view. This command works the same way as the Create distance command in the Custom component editor.
Add Distance > Reference
Creates a reference distance between model objects, which you can include in formulas in the Variables dialog box. This command works the same way as the Create reference distance command in the Custom component editor.

Creating variables Use variables to define the properties of a model object, such as a beam or column. Variables can define fixed properties, such as the name of a column. They can also include formulas, so that Tekla Structures calculates the property value each time you use the model object. The Model Editor includes the following tools for defining and editing variables:

Display settings Use the Display dialog box to define which object types Tekla Structures displays and how they appear in the model. Some of these settings may affect system performance.
TEKLA STRUCTURES 15 Modeling Settings
245
Field
Description
Parts
Defines how parts are displayed. Fast uses a rapid drawing technique that displays internal hidden
edges, but skips cuts. Exact displays the cuts, but hides the internal hidden lines of
parts. Reference line shows parts as sticks. This option increases display speed significantly, when viewing the entire model, or large parts of it. Bolts
Defines how bolts are displayed. Fast displays the axis and a cross to represent the bolt head. This
is the recommended representation mode for bolts, because it increases display speed significantly and consumes less system memory. Exact shows bolts, washers, and nuts as solids. Holes
Defines how holes are displayed. Fast only displays the circle in the first plane. When using this
option, Tekla Structures always displays fast holes on the first part (counting from the head of the bolt). If there are slotted holes in any of the parts, a slotted hole is displayed on the first part, even if the hole in that part is not slotted. The new slotted hole has the same size and rotation as the first slotted hole (counting from the head of the bolt). Holes that are outside a part are always displayed as fast holes in rendered views. Exact shows holes as solids. Exact long holes only displays slotted holes in exact mode and ordinary holes in fast mode. Point size
Defines the size of points in views. You can also change the size of the part handle using this field. In model increases the point size on the screen when you zoom
in. In view does not increase the point size. AutoStick
Defines whether the objects are shown as sticks or as objects. This option is only available in wire frame views. By dragging the sliders you can adjust the zoom distance where objects should be shown as reference lines. This option increases performance significantly when viewing large models. It still lets you zoom in on a small area and display it exactly.

Weld properties Use the Weld Properties dialog box to view or modify the properties of a weld.
Field
Description
Size
The size of the weld. 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. 257).
Angle
The angle of weld preparation, bevels, or groove. Tekla Structures displays the angle between the weld type symbol and the fill type contour symbol.
Contour
Finish
The fill type contour of a weld can be:
•
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
The center-to-center spacing of welds for non-continuous welds. 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 to @.
Prefix
See Weld size prefixes (p. 137).
Reference text
Additional information to appear in the weld symbol. For example, information about the weld specification or process.
Root face
Root face thickness 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.

8.5 Numbering settings This section provides more information about specific numbering settings.
General numbering settings Use the Numbering Setup dialog box to view and modify some general numbering settings.
TEKLA STRUCTURES 15 Modeling Settings
259
Option
Description
Renumber all
All parts get a new number. All information on previous numbers is lost.
Re-use old numbers
Tekla Structures reuses the numbers of parts that have 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.
Compare to old
The part gets the same number as a previously numbered similar part.
Take new number
The part gets a new number even if a similar numbered part already exists.
Keep number if possible
Modified parts maintain their previous numbers if possible.
Synchronize with master model
Use this setting when working in multi-user mode. Tekla Structures locks the master model and performs a save, numbering, and save sequence, so that all other users can continue working during the operation.
Automatic cloning
If the main part of a drawing is modified and therefore gets a new assembly position, the existing drawing is automatically assigned to another part of the position. If the modified part moves to an assembly position that does not have a drawing, the original drawing is automatically cloned to reflect the changes in the modified part.

Holes
The location, size, and number of holes affects numbering.
Part name
The part name affects numbering.
Beam orientation
The orientation of beams affects numbering.
Column orientation
The orientation of columns affects numbering.
Reinforcing bars
The orientation of reinforcing bars affects numbering.
Embedded objects
The orientation of equal embedded objects affects numbering.
Surface treatment
Surface treatments affect the numbering of assemblies.
Tolerance
Parts can get the same number if they do not differ more than as set in this input field.

Modeling Tips
This section provides useful hints and tips that help you to model structures more quickly and accurately, and avoid potential problems with templates and drawings. Contents
• •
General modeling tips (p. 263) Part positioning tips (p. 264)
9.1 General modeling tips These tips will help you to use some basic modeling functionalities more efficiently.
Copying and moving efficiently You can keep the Move and Copy dialog boxes open if you are going to use them often, for example, when creating grids and levels in a new model. To keep a dialog box open while modeling: 1.
Start the Move or Copy command.
2.
To stop copying or moving objects, right-click and select Interrupt from the pop-up menu. The dialog box remains open on the screen.
3.
To continue copying or moving objects: a Click the dialog box to activate it. b
Select an object.
c
Enter the values you want to use, and then click the Move or Copy button in the dialog box.
Activating an overlapping view When you want to pick positions from two views that partly overlap, you can use the Xmouse option. With Xmouse active, simply moving the mouse pointer over a view activates the view.
TEKLA STRUCTURES 15 Modeling Tips
263
To activate a view using Xmouse: 1.
Click Tools > Options > Xmouse to switch on Xmouse. A check mark appears next to the menu option if Xmouse is already switched on.
2.
To activate a view, do one of the following:
• •
Move the mouse pointer over the view. Use the Page Up, Page Down and arrow keys.
Finding RGB values for colors To find RGB values for colors: 1.
Log in to the Tekla Extranet.
2.
Click Tekla Structures > Hints & Tips > General.
3.
Go to the How to find perfect background color for your needs page.
4.
Download and install the application.
9.2 Part positioning tips These tips will help you to efficiently create and position parts in a view.
Modifying part length To modify the length of a part, do one of the following: •
To shorten a part, move the part handles, or use the Fit Part End command.
•
To lengthen a part, move the part handles.
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.
Do not use fittings to lengthen parts. It can cause problems with connections and details.
Creating horizontal parts When creating horizontal parts, always pick points from left to right, and from bottom to top (in positive x, y directions). 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.

TEKLA STRUCTURES 15 Modeling Tips
Optional ways of placing objects in a model When you want to place an object to a position where no lines or objects intersect, you have the following options:
• • • See also
Use the snapping commands. Use construction planes, lines and circles. Create points.
Snapping to positions (p. 50) Construction objects (p. 84) Points (p. 85)
Positioning objects in a radial or circular pattern To position objects in a radial or circular pattern, do one of the following:
See also
•
Create a grid line and use the Copy Special > Rotate command to copy it.
•
Use construction lines and circles to position the objects.
