Notes
(0069572) apv (tester) 2017-08-18 12:55	Problem described in issue is reproduced on current state of OCCT.

(0089601) eryar (developer) 2019-12-17 14:48 edited on: 2019-12-17 14:48	I have imported the d:/revol.step file into AutoCAD, see the revol.png and the shape looks OK. So I think its the mesh algorithm bug.
