Super Circular Truss — User Manual
1. Overview
Super Circular Truss is a procedural circular truss generation tool provided by SuperStage. It uses polar coordinate positioning and segment-based assembly to generate complete ring truss structures.
Core Features
- Outer/inner ring — Supports single-ring or dual-ring structure
- Radial braces — Radial support between inner and outer rings
- Connection flanges — Connectors between segments
- Section selection — Box (square) / Triangle / Flat sections
- Segment control — Controls arc shape via arc angle and segment count
- Multiple sizes — S290 / S400 / S520
Use Cases
- Circular lighting rigs (e.g., concert center lighting rig)
- Arc-shaped stage ceiling structures
- Semi-circle/quarter-circle arc truss structures
2. Differences from Super Truss Gantry
| Feature | Super Truss Gantry | Super Circular Truss |
|---|---|---|
| Shape | Straight segment combinations (goal post/T-shape, etc.) | Arc/complete circle |
| Positioning | Cartesian coordinates | Polar coordinates (radius + angle) |
| Dual-layer | No | Supports outer + inner ring |
| Radial braces | No | Supported |
3. Main Parameters
3.1 Arc Parameters
| Parameter | Description |
|---|---|
| Radius | Outer ring radius (cm) |
| ArcAngle | Arc angle (360° = complete circle) |
| SegmentCount | Number of segments |
| SectionType | Section type: Box / Triangle / Flat |
| TrussSize | Size: S290 / S400 / S520 |
3.2 Dual-Ring Parameters
| Parameter | Description |
|---|---|
| bInnerRing | Enable inner ring |
| InnerRadius | Inner ring radius (cm) |
| bRadialBraces | Show radial braces |
3.3 Component Visibility
| Parameter | Description |
|---|---|
| bShowFlanges | Show connection flanges |
| bShowDiagonals | Show diagonal braces |
4. ISM Components
| Component | Elements |
|---|---|
| OuterChordISM | Outer ring chords |
| OuterDiagonalISM | Outer ring diagonals |
| InnerChordISM | Inner ring chords |
| InnerDiagonalISM | Inner ring diagonals |
| RadialBraceISM | Radial braces |
| FlangeISM | Connection flanges |
5. Usage Tips
- Set ArcAngle=360° for complete circle, 180° for semi-circle
- More segments = smoother but more components
- Inner radius must be smaller than outer radius
- Radial braces only available in dual-ring mode
