Inserting a curved truss

Insert and configure curved trusses with the Curved Truss tool. Curved trusses function as rigging objects, so lighting devices and other loads can attach directly to the truss. Curved trusses support full 3D rotation, and they can be used to create schematic views.

2.Click to define the truss insertion point. Click again to set the rotation of the curved truss.

The first time you use the tool in a file, a properties dialog box opens. Set the default parameters. The parameters can be edited later from the Object Info palette.

Trusses are 2D/3D hybrid objects. Complex trusses can increase the time required to render the model in 3D.

Parameter	Description
Roll	Rotates the truss on its X axis; the truss rotates around its insertion point
Hanging Angle	Rotates the truss on its Y axis; the truss rotates around its insertion point. When this angle is adjusted, attached load objects may appear to overlap in Top/Plan view.
Rotation	Rotates the truss on its Z axis; the truss rotates around its insertion point
Name	Specifies the name of the truss, for identification and reporting purposes
Index	Specifies a unique identifier for the truss, which is combined with the Name for identification and reporting purposes
Diameter	Specifies the diameter of the truss as measured from the industry standard outside-to-outside diameter
Total Arc	Indicates the total angle covered by the truss in degrees
Segment Arc	Specifies the interval in degrees for dividing the truss into component sections
Cross Section	Displays the associated cross section for Braceworks structures
Truss Cross Section	Displays the cross section unique ID number, when a cross section file has been associated with the truss as described in Specifying cross section data. Cross section information is required for valid calculations; if there is no identified cross section, calculations will not be complete.
Connection	Select the type of connection from the list
Profile	Select the truss profile from the list
Height/Width	Shows height and width values for the truss
Chord Profile	Select round or square chord tubing
Chord Width	Specifies the diameter of round chords or the width of square chords
Ladder Spacing Arc	Specifies the interval of the ladder bars in degrees
Ladder Profile	Select round or square ladder bar tubing
Top/Side Ladder Bar Diameter	Specifies the diameter of the top and side ladder bar tubing. Enter 0 (zero) to draw no ladder bar.
Lacing Profile	Select round or square lacing tubing
Top/Side Lacing Diameter	Specifies the diameter of the top and side lacing tubing. Enter 0 (zero) to draw no lacing.
Distributed Weight	Specifies the weight of the truss along the length of the truss
Show 3D Detail	Renders the truss with greater 3D detail
Highlight	Displays odd sized truss divisions in red
Message	Provides information about the truss placement and indicates successful placement
Select Truss System	Selects the current truss and any other connected structural elements in the system
Convert to Hanging Position	Selects the entire system, including the truss and any connected rigging objects, for conversion to one or more hanging positions. Any attached loads are associated with the created hanging position(s); see Creating a hanging position object.

If the final segment of a truss is shorter than the defined interval length, it is displayed in red when Highlight is selected.
