API Reference > geometry-core > CartesianGeometry > ClipPlane > polygonCrossings polygonCrossings Method Deprecated ClipPlane method clipPlane.polygonCrossings(polygonPoints, crossings) is deprecated. Use Point3dArrayPolygonOps.polygonPlaneCrossings (clipPlane, polygonPoints, crossings)` Return an array containing All points that are exactly on the plane. Crossing points between adjacent points that are (strictly) on opposite sides. polygonCrossings(xyz: Point3d[], crossings: Point3d[]): void Parameter Type Description xyz Point3d[] crossings Point3d[] Returns - void Defined in core/geometry/src/clipping/ClipPlane.ts Line 507 Last Updated: 13 June, 2024
