I have an stl file and i would like do automatically the following passages:
→ extract all points which belongs to Zmin < points < Zmax
→ find polygons obtained
for example i have a stl of a cube and a cone.
If i cut the geometry I obtain a square and a circle. Can I find automatically that poligons from points connecting them.
this is for a cnc project which I’d like to write
many thanks in advance
