| Summary | 0025061: BRepMesh should skip internal wires with self intersections to produce mesh for the shape anyway | ||||
| Description | BRepMesh fails to mesh shapes containing self intersected wires. Attached shape contains two problematic faces - 172 and 227. Each of them have internal wires with self intersections and in addition these wires define contours with insignificant areas (see attached screenshot, problematic wires are marked by red). As far as in general BRepMesh is supposed to be used for visualization needs it is preferred to produce discrete presentation of a shape anyway even if it will not contain some details. For this case it is supposed to introduce new flag BRepMesh_SkippedWire. Note that if the outer wire of the face contains self intersections, mesher should implement its usual behavior, i.e. notify BRepMesh_SelfIntersectingWire and skip the whole face. | ||||

Fix 0026106 creates some mesh. But it contains free nodes and free edges. |
