Super Curved Truss User Manual

Purpose

Super Curved Truss generates truss along a spline path. After selecting the Actor, edit the spline points in the viewport and the truss follows the updated path.

Use it for free-form lighting rigs, wave-shaped suspended structures, and non-standard truss paths in visualization scenes.

Main Parameters

Parameter	Description
SectionType	Section type: Box, Triangle, or Flat.
TrussSize	Truss size: S290, S400, or S520.
BracePattern	Brace pattern: Warren or Cross.
SpanCountAlongSpline	Number of spans along the spline. Higher values create finer path segmentation.
SectionRotation	Rotates the section around the spline direction.
SuspendedLoad	Suspended load used by the simplified statistics.
DistributedLoad	Distributed load used by the simplified statistics.
bShowHorizontalBraces	Shows horizontal braces.
bShowEndPlates	Shows end plates at both ends.
ChordMaterial	Material for chord members.
BraceMaterial	Material for brace members.
EndPlateMaterial	Material for end plates.

Spline Editing

• Select the Actor and move spline control points in the viewport to change the truss path.
• Add more control points for more complex curves.
• Use SectionRotation to adjust the section orientation, such as turning a triangular section upward or sideways.

Statistics

The Actor updates these values from the current spline and parameters:

• PartCounts: instance counts for chords, braces, end plates, and related parts.
• WeightStats: simplified estimates for self weight, suspended load, maximum point load, maximum distributed load, deflection, and reaction per upright.
• CurrentProfile: profile data for the selected section and truss size.
• BaySizeAlongSpline: bay length along the spline.
• SplineTotalLength: total spline length.

Notes

• The spline needs at least two valid points.
• More spans give a finer shape but increase instance count.
• Load and deflection values are quick estimates only. They do not replace structural engineering calculations or site approval.
