Truss Parameters

Architectural, Framer

Select the truss parameters in a dialog box.

Dialog Box Options

Select
You can select a standard truss or a frame truss by clicking the Select button. After this, you can select the shape-specific parameters. If necessary, you can edit the parameters by clicking the Params button.

Parameters
Edit the shape-specific truss parameters by clicking the Params button, if necessary.
Standard Truss Parameters
Frame Truss Parameters
Thickness
Type the truss thickness in the field.
Label type
Select from the list or type the desired character string in the text field. The type will be used as the prefix of the truss labels created later.
Use
Select from the list. The options on the list are customer-specific.
Spacing
Type the truss spacing in the text field.
Offset first truss
Enter the offset (d) from the clicked start point of the truss line for the first truss. The offset is measured to the edge or center of the truss, depending on whether the auxiliary function for fitting the truss is used or not when adding the truss area.
By default, the offset is 0.
= clicked point of truss line
Truss Adjustment
Offset last truss
Enter the offset (d) from the clicked end point of the truss line for the last truss. The offset is measured to the edge or center of the truss, depending on whether the auxiliary function for fitting the truss is used or not when adding the truss area.
By default, the offset is 0.
= clicked point of truss line
Truss Adjustment
2D visibility
You can make the truss visible in 2D drawings by clicking the 2D visibility check box. Select either Line or Box as the method of configuration. 2D properties define the line drawing properties in the 2D drawing. The property set needs to be defined in the GEOMPROP keyword group in the system settings.
3D visibility
You can make the truss visible in 3D models by clicking the 3D visibility check box. Select either Line or Volume as the method of configuration. 3D properties define the line drawing properties in the wire frame model. The property set needs to be defined in the GEOMPROP keyword group in the system settings. The Surface properties determine the surface color in the shaded model. The color needs to be defined in the d_LWMAP database.
Ply
You can add the trusses as single, double or triple trusses. Select one of the following from the list:
  • 1 - Single truss
  • 2 - Double truss
  • 3 - Triple truss
Function
The parameter is used to export truss information to an external truss design software. Select one of the following options:
  • Regular - Regular truss
  • Girder - Truss supporting other trusses
  • Gable - Gable truss on a wall
  • Str Gable - Gable truss and vertical truss members
Structure
The parameter is used to export truss information to an external truss design software. Select one of the following options:
  • Standard
  • Valley
  • Gable
  • Flat, Floor
Label
Select the location of the truss label by clicking one of the following options:
  • Horizontal = label in the direction of the x axis
  • Parallel left = label in the direction of the truss, the left edge of the truss determined by viewing the truss from the end of the truss line towards the beginning
  • Parallel mid = label in the direction of the truss, in the center of the truss
  • Parallel right = label in the direction of the truss, the right edge of the truss determined by viewing the truss from the end of the truss line towards the beginning
Note:
  • You can edit the parameters of the entire truss area with the function Edit the Truss Area Parameters.
  • You can edit the method of configuration of trusses in the model or drawing by editing the truss properties, see Edit the Truss Parameters.
  • The default parameter values are defined by truss type in the system settings in the truss.setup keyword group. For example, the label location with the keyword:

    param= LBLD x

    x may have the following values:
    • 0 - horizontal
    • 1 - center
    • 2 - left
    • 3 - right
