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.
constructOffsetXY(offsetDistanceOrOptions: number | OffsetOptions): BSplineCurve3d | undefined
| Parameter | Type | Description |

| offsetDistanceOrOptions | number | OffsetOptions | offset distance (positive to left of the instance curve), or options object. |
Returns - BSplineCurve3d | undefined
