Truss Object Type Properties

Name Description
Top Chords
Structural Framing Type Defines the structural framing type of the top chords.
Start Release Defines the release conditions: either Pinned, Fixed, and Bending Moment.
End Release Defines the release conditions: Available choices are Pinned, Fixed, and Bending Moment.
Angle The rotation about the longitudinal axis of the shape.
Analytical Vertical Projection Specifies the location for the respective analytical lines. If you select Auto-detect, the analytical models follow the same rules as beams.
Vertical Webs
Structural Framing Type Defines the structural framing type of the vertical webs.
Start Release Defines the release conditions: either Pinned, Fixed, and Bending Moment.
End Release Defines the release conditions: either Pinned, Fixed, and Bending Moment.
Angle The rotation about the longitudinal axis of the shape.
Diagonal Webs
Structural Framing Type Defines the structural framing type of the diagonal webs.
Start Release Defines the release conditions: either Pinned, Fixed, and Bending Moment.
End Release Defines the release conditions: either Pinned, Fixed, and Bending Moment.
Angle The rotation about the longitudinal axis of the shape.
Bottom Chords
Structural Framing Type Defines the structural framing type of the bottom chords.
Start Release Defines the release conditions: either Pinned, Fixed, and Bending Moment.
End Release Defines the release conditions: either Pinned, Fixed, and Bending Moment.
Angle Rotation about the longitudinal axis of the shape.
Analytical Vertical Projection Specifies the location for the respective analytical lines. If Auto-detect is chosen, the analytical models will follow the same rules as beams.
Construction
Webs Have Symbolic Cutback Enables the cutback of the coarse representation of webs.
Revit Structure

The cutback distance is defined by the Braces cutback setting in the Structural Settings dialog. For more information, see Structural Settings Dialog.

Web Orientation Specifies the orientation of the web: either vertical or perpendicular. The default setting is vertical. Webs set to vertical maintain a vertical orientation in the project. If they are set to perpendicular, they maintain a 90 degree angle with respect to the bearing chord they are connected to.
Identity Data
Keynote Used to add or edit the truss keynote. Click in the value box to open the Keynotes dialog. For more information, see Keynotes.
Model The manufacturer internal number.
Manufacturer The truss manufacturer.
Type Comments A field for entering general comments about the truss type. This information can be included in a schedule.
URL A link to a web page that may contain type-specific information.
Description The description of the truss.
Assembly Code The description of the assembly, based on the assembly code selection. This is a read-only value.
Type Mark A value that designates a particular truss; possibly the shop mark. This value must be unique for each truss in a project. Revit warns you when the number is already used, but allows you to continue using it. You can see the warning using the Review Warnings tool. See Reviewing Warning Messages.
Cost The cost of the truss type.
OmniClass Number The number from Table 23 of the OmniClass Construction Classification System that best categorizes the family type.
OmniClass title The name from Table 23 of the OmniClass Construction Classification System that best categorizes the family type.
