SmApiStatus SmApiFaceGetBoundaryLoops(

SmFace *pFace,

SmTArray<ULONG> &rEdgeCountsPerLoop,

SmTArray<SmEdge*> &rEdges,

SmTArray<SmOrientType> &rOrientations,

)

Parameters:

• pFace – [in ]: Face to query

• rEdgeCountsPerLoop –

  [out]: Edge-occurrence count for each loop, outer loop first;

  later-loop order is unspecified; a vertex-only loop

  contributes a zero count

• rEdges –

  [out]: Borrowed Brep-owned edges, flattened loop by loop in

  traversal order; each loop’s starting occurrence is

  unspecified; repeated seam occurrences are retained;

  invalid after the owning Brep’s topology changes

• rOrientations –

  [out]: Orientation per edge occurrence; SM_OT_SAME traverses

  edge start/min to end/max, SM_OT_OPPOSITE traverses reverse
