Problem described in issue is reproduced on current state of OCCT. |
|
|
Original shape is non-manifold (corners touch each other). In case the original shape is splitted into two faces, the issue doesn't occur. When importing the STEP-file, are there any repairing mechanisms trying to repair some intersections and can't handle self-intersections due to non-manifold geometry? The issue occurs also with IGES and with Parasolid (via CADExchanger). |
