I have an issue saving a TopoDS_Shape to an IGES or STEP file. For completeness, the shape was created through BRepOffsetAPI_ThruSections and then cut with a Boolean Operation. When I write the file to an IGES file, it reports success, but I cannot load the file into any other program (ProE, CadExchanger, ...). However, if I save the Shape into a .brep file, load it into Roman's CadExchanger, and export it to IGES there, everything is fine. So I must be doing something wrong here. Can anyone help? Here is the code to save "aRes" into IGES and then BRep.
Standard_Boolean OK = ICW.Write("wing.igs");
Thanks for the help.
