Curved Truss

Design Suite: Detailing

Spotlight: Rigging/Braceworks

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.

Curved truss parameters are illustrated by the following diagram.

To add a curved truss to the light plot:

Click the tool and modes.

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

Trim Height

Specifies the height of the lowest point on the object; it is the absolute height of the truss compared to the ground level. Trim height could be different from the Z height if the object is rotated with its its roll or hanging angles, or if its insertion point is not the lowest part of the object.

Roll Angle

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

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

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.

Equipment Subparts

Lists the subparts that make up the object. These subparts are counted and reported separately in equipment and inventory lists.

The parameters must be selected for display for this type of object in Spotlight preferences: Inventory pane.

Equipment Virtual Parts

Virtual parts are associated with an object and are reported in equipment and inventory lists, but do not display in the drawing. After adding virtual parts, they are listed in the Object Info palette.

Edit Virtual Parts

Opens the Virtual Parts dialog box to add virtual parts to the object; see Managing virtual parts and independent virtual parts

Assign Sources

Opens the Assign Sources dialog box to assign the object and its subparts and virtual parts to an inventory source; see Assigning equipment to an inventory

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