constructOffsetXY Method

Construct an offset of the instance curve as viewed in the xy-plane (ignoring z).

  • No attempt is made to join the offsets of smaller constituent primitives. To construct a fully joined offset for an aggregate instance (e.g., LineString3d, CurveChainWithDistanceIndex), use RegionOps.constructCurveXYOffset() instead.
