| Summary | 0021060: Triangulation fails on non-manifold face with SI wire | ||||
| Description | The triangulation algorithm fails on face with self intersection wire, which contains free edge (or edges) not connected to other part of wire. This face extracted from test case shd 002 A9, which detects as "regression" comparing with OCCT630 for OCC20846. The extracted face (in attachment): A9_205.brep - initial BRep file with face a9_205.gif - snapshot from 3D view with isolines a9_205_sh.gif - shading in OCCT630 Currently, there are no shading presentation for this face, because of expection in MeshData class, which indicates problem with Mesh data structure. It is not necessary to fix exception, because it is flag of detected problem. We should try to detect problem areas of Shape in BRepMesh and doesnot try to create triangulation on invalid parts of shape. | ||||

Incmesh and checkshape commands indicate self-intersection. So, the target of this issue has already been achieved - BRepMesh detects problem areas of a shape and breaks the triangulation procedure if some is detected. I propose to close it. |
