VLofVLFLselfIntersection
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Surfaces
Introduced first in SolidGeometry 4.3, Creation date: 2018-08-25, Last change: 2025-09-14
returns the self intersection crossing points of a Surface
Description
Only original facet points are not returned
Function could be improved by returning the crossing facets
