| Summary | 0033880: Scaling with BRepBuilderAPI_GTransform crashes when the shape has triangulation | ||||
| Description | The code in the next box crashes in the end. It works OK if you comment out the BRepMesh_IncrementalMesh(shape0, 0.5, Standard_False, hPi); line BTW this form has problems. It crashes when I click submit | ||||
| Steps To Reproduce | void BRepBuilderAPI_GTransformTst::Test0() { // Rectange double width = 2; double height = 1; gp_Pnt P0(0, 0, 0), P1(width, 0, 0), P2(width, height, 0), P3(0, height, 0); gp_Pln plane = gce_MakePln(P0, P1, P2); // On first three BRepBuilderAPI_MakeFace MF(plane); TopoDS_Wire W = BRepBuilderAPI_MakePolygon(P0, P1, P2, P3, Standard_True); MF.Add(W); TopoDS_Face F = MF; double factor = 1.5; gp_GTrsf gTrsf0; gTrsf0.SetValue(1, 1, factor); gTrsf0.SetValue(2, 2, factor); gTrsf0.SetValue(3, 3, factor); BRepBuilderAPI_GTransform gBRepTrsf(F, gTrsf0); TopoDS_Shape shape0 = gBRepTrsf.Shape(); BRepCheck_Analyzer analyser(shape0); ASSERT(analyser.IsValid()); // The critical line. The exception does not happen without it: BRepMesh_IncrementalMesh(shape0, 0.5, Standard_False, hPi); gp_GTrsf gTrsf1; gTrsf1.SetValue(1, 1, factor); gTrsf1.SetValue(2, 2, factor); gTrsf1.SetValue(3, 3, factor); BRepBuilderAPI_GTransform gBRepTrsf1(shape0, gTrsf1); TopoDS_Shape shape1 = gBRepTrsf1.Shape(); BRepCheck_Analyzer analyser1(shape1); // An exception inside the constructor ASSERT(analyser1.IsValid()); } | ||||

Submitting works if I just repeat. This also happened last time two weeks ago with the previous my bug |

Dear @NickZ the issue must to be resolved on latest version. If not - please let me know. The main bug tracker migrated to https://github.com/Open-Cascade-SAS/OCCT The issue from current BT are moved manually when started to fix. No global migration is planned. |
