| Summary | 0023203: STEP import produces wrong surface of revolution on ellipse | ||||||||
| Description | Regression caused by #952 STEP importer produces wrong surface of revolution when axis of revolution goes through the ellipse location and lies in its plane. The root-cause is fix #952 in StepToGeom_MakeSurfaceOfRevolution::Convert() which produces a regression on ellipses. Apparently the fix 952 was wrong: - it changes the ellipse axes - even on circles (when geometrical form is preserved) it may change original surface parametrization and hence pcurve in the file will be imported wrong. With that, the fix #952 needs to be revisited and at best removed. It should be Shape Healing's job, not particular format importer's, to handle such case. Perhaps this is not needed at all - perhaps OCC can handle such revolved surfaces well (note that face f from reproducer is valid and displayed well, and checkshape claims valid). P.S. Public access to #952 is denied, so it is impossible to verify original model that required that fix. | ||||||||

Reassigned to skl, the author of #952 |

The branch CR23203 created and pushed into the repository. Please review. (Please note that the fix has not been compiled or tested explicitly - only manually verified in debugger, by skipping the code of fix952) |

I believe that fix for bug 952 is useful for circles and cases for ellipses which axis coincided with axis of rotation. Therefore I think that existed fix for bug 952 needs to change but not remove. |

Checking of ellipse axis was added. Git branch CR23203_1 is ready to be reviewed. Dear SKL, Please review. |

OK |

Dear BugMaster, Branch CR23203_1 (and products from GIT master) was compiled on Linux and Windows platforms and tested. Regressions: Not detected Improvements: Not detected Testing cases: bugs step(008) bug23203 - OK. |
