API Reference > geometry-core > Solid > SweepContour > sweepToUnionOfConvexClipPlaneSets sweepToUnionOfConvexClipPlaneSets Method Triangulate the region. Create a UnionOfConvexClipPlaneSets that clips to the swept region. If sweepVector is not given, the sweep direction is perpendicular to the plane of the contour. If sweepVector is given, it is the sweep direction and does not have to be perpendicular to the contour. cap0 and cap1 indicate construction of clip planes parallel to the contour plane. If cap1 is true, the cap plane is at anyPointOnPlane + sweepVector. That is, the sweep vector indicates both direction and distance. caps are NOT created of sweepVector is not given. sweepToUnionOfConvexClipPlaneSets(sweepVector?: Vector3d, cap0: boolean = false, cap1: boolean = false): undefined | UnionOfConvexClipPlaneSets Parameter Type Description sweepVector Vector3d cap0 boolean cap1 boolean Returns - undefined | UnionOfConvexClipPlaneSets Defined in solid/SweepContour.ts Line 232 Last Updated: 12 June, 2024
