RigArc - User Guide
Fast rigging pickup coordinates
Fast Start
- Create or open a project.
- Set units, stage width, stage depth, and datum in Settings.
- Enter Main SL front coordinate in Arrays (or adjust the default).
- Sub, Side, 270, and Rear are on by default; turn off any you don't need.
- Set bumper spacing, azimuth, and placement modes per array.
- Review points in Results and export CSV.
Coordinate Convention
- X positive is SR
- X negative is SL
- Y positive is downstage
- Y negative is upstage
Datum Notes
- Datum can be DSC, USC, or Custom.
- Displayed values update automatically when datum changes.
Settings
- Arc center (USC, Center Stage, DSC, or Custom) controls where 270 and Rear arcs are centered.
- Grid sets origin and spacing; enable global snap to snap array fronts to the grid.
- Interference frequency uses temperature-based speed of sound for half-wavelength rows; turn on custom temperature to override.
- Array display names are optional; leave blank to use default names (Mains, Subs, Sides, 270, Rear) in Results and CSV.
Array Notes
- SR is mirrored from SL.
- Delta arrays use front index 0 and rear indices 2 and 3.
- 2 point arrays use front index 0 and rear index 1.
- Sub has two rigging modes: Front/Rear and Side-by-side.
- In Sub Side-by-side mode, side-by-side spacing is the distance between the two sub points.
- In Sub Side-by-side mode, the midpoint between those two points is constrained to the selected arc.
- Side and other non Sub categories can use Delta Plate to output indices 2 and 3.
Preview Notes
