| Summary | 0024490: Computed surface properties differ substantially depending on NaturalRestriction flag | ||||
| Description | The same face with and without NaturalRestriction flag produces substantially different surface properties (areas, center of gravity, moments inertia, etc). For instance, surface areas differ by more than 2x. When NR is set, the surface area seems to be more correct. As a result, the algorithm that depends on surface area as a hint fails being given significantly different value. | ||||
| Steps To Reproduce | Draw[1]> pload MODELING Draw[2]> restore face_naturalrestriction_flag.brep ff Draw[3]> sprops ff Mass : 46.3749 Center of gravity : X = 14.1304 Y = 29.4519 Z = 9.99987 ... Draw[4]> restore face_naturalrestriction_noflag.brep fn fn Draw[5]> sprops fn Mass : 21.7827 Center of gravity : X = 11.4146 Y = 29.8415 Z = 9.99987 ... The test face has been produced from the underlying surface and then modifying the natural restriction flag in text editor: mksurf s ff mkface f s save f face_naturalrestriction_flag.brep | ||||
