Just a question... Does the quad should be plane, is there any problem to get 4 non-coplanar points ? Damien. (25 years ago, 29-Mar-00, to lugnet.cad.dev)
(...) Quads should be plane and follow a correct order, the points must be in a correct order. Search the old messages and you'll find several discussions about it. Leonardo (25 years ago, 29-Mar-00, to lugnet.cad.dev)
