API Reference > geometry-core > CartesianGeometry > ClipPrimitive > ensurePlaneSets ensurePlaneSets Method trigger (if needed) computation of plane sets (if applicable) in the derived class. Base class is no op. In derived class, on first call create planes sets from defining data (e.g. swept shape). In derived class, if planes are present leave them alone. ensurePlaneSets(): void Returns - void Defined in clipping/ClipPrimitive.ts Line 163 Last Updated: 11 June, 2024
