regionBooleanXY MethodStatic
Return areas defined by a boolean operation.
regionBooleanXY(loopsA: AnyRegion | AnyRegion[], loopsB: AnyRegion | AnyRegion[], operation: RegionBinaryOpType, mergeTolerance: numberGeometry.smallMetricDistance): undefined | AnyRegion
@note For best results, input regions should have correctly oriented loops. See sortOuterAndHoleLoopsXY.
@note A common use case of this method is to convert a region with overlapping children into one with
non-overlapping children: regionOut = RegionOps.regionBooleanXY(regionIn, undefined, RegionBinaryOpType.Union).
@returns a region resulting from merging input loops and the boolean operation. May contain bridge edges added to connect interior loops to exterior loops.
| Parameter | Type | Description |
|---|---|---|
| loopsA | AnyRegion | AnyRegion[] | first set of loops (treated as a union) |
| loopsB | AnyRegion | AnyRegion[] | second set of loops (treated as a union) |
| operation | RegionBinaryOpType | indicates Union, Intersection, Parity, AMinusB, or BMinusA |
| mergeTolerance | number | absolute distance tolerance for merging loops |
Returns - undefined | AnyRegion
a region resulting from merging input loops and the boolean operation. May contain bridge edges added to connect interior loops to exterior loops.
