Summary | 0001934: OCCT algorithms can't handle zero derivatives | ||||
Description | many OCCT algorithms fail if a derivative becomes zero. Those appear in Bezier curves when their first (or last) pole is duplicated. This seriously affects imported paths form SVG files and some SPLINES from DXF files. | ||||

@ickby do you mind asking the OCCT devs to add http://tracker.dev.opencascade.org/view.php?id=25730 to their roadmap ? |
