| Summary | 0025157: Face missing depending the angle of revolution | ||||

I added shapes for the existing workarounds. One known workaround is to change the angle of revolution (here 181) degree. The second workaround has the tip of the cone removed, which creates an additional face. |

I created a DRAWEXE script to reproduce the problem that does not rely on external shapes, to be used as a test case: pload MODELING pcone Cone 6 0 10 180 pcylinder Cylinder 1 6 360 ttranslate Cylinder 0 3 1 bcut Cut Cone Cylinder explode Cut F tclean Cut_1 incmesh Cut_1 0.1 #Incremental Mesh, multi-threading OFF #Meshing statuses: SelfIntersectingWire trinfo Cut_1 # #This shape contains 0 triangles. # 0 nodes. #Maximal deflection 0 donly Cut_1 |

Please add a test case |

Dear ABV, Fact that this problem was being fixed by 0023106 is just a side effect that does not fix problem in general (see 0025045). I suggest leaving this bug open as long as 0025045 will not be fixed. |
|

Oleg, if the problem is not reproduced any more, it is right time to add a test case and integrate it to master; this will let us know if some other change will break the case. The issue can be closed then, as there is no utility in having it open. Do you agree on this? |
|
|
Yes, sounds reasonable. |
