| Summary | 0033903: ShapeFix_Shape crashes | ||||
| Description | Applying ShapeFix_Shape to the attached brep causes a crash. Setting aSfs.FixSolidMode() = false avoids this issue, maybe because this is a Moebius-type shape, but it should not cause a crash anyway. | ||||
| Steps To Reproduce | TopoDS_Shape shape ; BRep_Builder builder ; BRepTools::Read(shape, "shape.brep", builder) ; ShapeFix_Shape aSfs(shape) ; aSfs.SetPrecision(1.0e-4) ; aSfs.SetMinTolerance(1.0e-6) ; aSfs.SetMaxTolerance(1.0e-3) ; aSfs.Perform() ; | ||||

Example in attached file shape.brep (758,026 bytes) |

It seems that writing then reading the brep solves the issue but I can't do that each time. The original shape comes from a STEP. Here is the file. CADAssistant crashes when we try to open it, but https://viewer.autodesk.com works. Shape.step (1,404,530 bytes) |
