Sheet Metal Contour Flange
Status: Implemented (engine-backed)

Contour Flange builds a base sheet-metal tree from an open path (sketch/edge chain) and evaluates it using the shared deterministic sheet-metal core.
Inputs
path– Connected edge chain (from sketch, edges, or face boundaries).distance– Strip width offset from the path.thickness– Global model thickness.reverseSheetSide– Flips offset side and placement direction.bendRadius– Default inside bend radius stored for downstream operations.neutralFactor– Default k-factor stored for downstream operations.consumePathSketch– Removes source sketch group when enabled.
Behavior
- Converts the selected path into a strip-like root
FlatSurface. - Evaluates the resulting tree to produce synchronized folded 3D and unfolded 2D representations.
- Adds selectable face/edge overlays tagged with
flatId/edgeIdfor downstream flange/hem targeting. - Persists tree and root transform in
persistentData.sheetMetal.
