Summary 0027015: Sewing returns invalid shape if some faces are nearly plane cones
Revision 2015-12-18 18:51 by Timo
Description When sewing a couple of faces, which should form a closed solid, an invalid Shell is returned. checkshape says that some faces have self-intersecting wires. These faces are cones that are nearly planes. If These faces are modified to be real planes, sewing works fine. So, it seems to be connected with this type of geometry. I think it would be good, if sewing could handle such cases more robustly, returning a valid result.

It was reproduced on OCC 6.9.0 and 6.9.1 (win32, vc10). I didn't test it on current master.
