API Reference > geometry-core > CartesianGeometry > ClipVector > extractBoundaryLoops extractBoundaryLoops Method A simple way of packaging this ClipVector's ClipShape points into a multidimensional array, while also taking into account each ClipPrimitive's individual transforms. ClipPrimitives OTHER THAN ClipShape are ignored. Information out: All of the loop points are stored in the multidimensional Point3d array given (will return unchanged upon failure) If given a transform, will be set from the transformFromClip of the first ClipPrimitive The ClipMask of the final ClipPrimitive is stored in the returned array at index 0 The last valid zLow found is stored in the returned array at index 1 The last valid zHigh found is stored in the returned array at index 2 extractBoundaryLoops(loopPoints: Point3d[][], transform?: Transform): number[] Parameter Type Description loopPoints Point3d[][] transform Transform Returns - number[] Defined in core/geometry/src/clipping/ClipVector.ts Line 175 Last Updated: 13 June, 2024
