Summary | 0031567: Data Exchange - Imported STeP model is missing two surfaces | ||||||||||||
Description | (This is really on 7.4.0, but that version is not available for selection). I analyzed one of the two surfaces (#586) and I see two problems. A) EDGE_CURVE #49 is a NURBS with parametrization [0,1]: it's closed but not periodic. It's limited by the same vertex, which projects at 0.997..., so its parametrization should become [0.997...,1.997...]. However, at StepToTopoDS_GeometricTool.cxx:305, these values are reset to [0,1]. B) Don't know if this is related to the above, but the face imports with 2 trimming edges, while in the STeP file there are 4. So the resulting loop doesn't make much sense. | ||||||||||||
