| Summary | 0024185: Modeling Algorithms - Wrong projection of a wire to a face | ||||
| Description | OpenCascade gives a wrong projection of the wire to the face1 (see attached files). The wire was constructed as an intersection between face1 and face2 and then smoothed by Approx_Curve3d. Both faces are attached, so you can compare the wire to the intersection of the faces yourself. | ||||
| Steps To Reproduce | Draw script:restore face1.brep f1 restore wire.brep w nproject r w f1 You can compare the wire in wire.brep to the intersection of the two faces: restore face2.brep f2 section s f1 f2 | ||||

The bug seems to be caused by numerical instability when approximating the projection by a bspline curve. If you increase allowed number of poles of the bspline curve and/or increase precision, the projection looks fine: nproject r w f1 0.0005 C0 14 1000 This is not so surprising, but maybe default precision/number of poles is too large or small, respectively? Even with few poles, could the approximation be more stable? |
