Standard Truss Parameters
Frame Truss Parameters

Thickness

Type the truss thickness in the field.

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.

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 representation. 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 representation. 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 position 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

The labels will be displayed in the 2D drawing after they have been generated, see Add Truss Labels and Generate Drawings.

Note

• You can edit the parameters of the entire truss area with the function Generate Trusses.
• You can edit the method of representation of trusses in the model or drawing by editing the truss properties, see Editing Truss Parameters.
