Straight Truss

StraightTruss_tool.png 

Design Suite: Detailing

Spotlight: Rigging

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

Straight truss parameters are illustrated by the following diagram.

To add a straight truss to the light plot:

Click the tool.

Click to place the object in the drawing, and click again to set the length and rotation.

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, the truss may appear shorter in Top/Plan view, and attached loads may appear to overlap.

Rotation

Rotates the truss on its Z axis; the truss rotates around its insertion point

Position Name

Enter a name for identification and reporting purposes. When the truss is used as a hanging position, this name automatically populates the Position field of any attached load objects.

Index

Specifies a unique identifier for the truss, which is combined with the Name for identification and reporting purposes

Length

Specifies the length of the truss in drawing units

Cross Section

Displays the associated cross section information 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.

Profile

Select the truss profile from the list

Connection

Select the type of connection from the list

Connection Interval

Indicates the distance for dividing the truss into component sections

Folding

Indicates a folding truss

Pre Rigged

Select whether to include a light bar

Height/Width

Shows height and width values for the truss

Chord Profile

Select round or square chord tubing

Chord Width

Shows the diameter of round chords or the width of square chords

Ladder Bar Spacing

Specifies the interval of the ladder bars

Ladder Bar Profile

Select round or square ladder bar tubing

Top/Side Ladder Bar Diameter

Indicates the diameter of the top and side ladder bar tubing; enter 0 to draw no ladder bar

Lacing Profile

Select round or square lacing tubing

Top/Side Lacing Diameter

Indicates 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

Show Direction

Places a directional indicator on the truss

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.

A connection interval shorter than the defined interval length is displayed in red when Highlight is selected.
