Summary0032185: Modeling Algorithms - Bad fillet on an internal edge of a revolution
DescriptionIf an external face of the revolution has a degenerated edge, a filleting face has bad limiting edge or too big tolerance.
In branch CR23731_7 a result solid shape has faulty result of the checkshape command. Also "test blend buildevol D6" and "test blend simple H4" failed in branch CR23731_7 failed because of this problem.
Steps To Reproduce
