Stand 3D PlusBUILD-001

Builds the 3D bowl: cuts the stand solids with everything the 2D chain decided — shape cuts, entrance openings, vomitories — and lifts the seats and aisle steps to their real tread heights.

Colored ports carry the chain from one component to the next. The rest are values you set once. Inputs marked ▾ take a Value List: wire one in and it fills with the choices.

Inputs

  • Stand BodySBDThe raw stand solids from Stand 3D. Unwired = rebuilt from the rings - rougher, and those bodies come out open, not closed solids
  • Seat ResultSRDThe 2D layout to build. Wire from Seat, or from Cut once you have cut the bowl
  • Wheelchair Deck Mode▾ Deck0 = INTEGRAL, cast into the tier body. 1 = PLATFORM, a separate deck on top (default 0)
  • Tier EnabledTiersWhich tiers to build - one per tier, empty = every tier (default true)
  • Panel ValuesPanelEvery value from Input Panel, as one bundle. Anything you wire in yourself wins over it

Outputs

  • Build ResultBRDThe 3D bowl as one object. Wire into Rail 3D
  • Stand BrepsBodiesOne branch per tier. A tier with vomitories is left open at the void - not an error
  • Aisles 3DAisles 3DOne branch per tier. Aisle steps as solids, raised to read as a real staircase
  • Wheelchair Decks♿ DecksOne branch per tier. Only filled in PLATFORM mode or when an INTEGRAL merge failed
  • DebugDebugDeveloper diagnostic output for tracking down bugs. Copy this when reporting a problem
