Notes
(0075678) nbv (developer) 2018-04-25 13:08	Please note that on OCCT 7.2.0 the result is looked more aesthetic. However, it is not valid, too. Because it contains too small edge. E.g. Draw[]> explode rr f Draw[]> copy rr_4 ff2 Draw[]> explode ff2 e Draw[]> lprops ff2_4 1.0e-4 # 1.21698e-007 Draw[]> toler ff2_4 # VERTEX : MAX=5.5040830459515754e-007 ... MIN=9.9999999999999995e-008 I.e. the edge ff2_4 is covered by the tolerance of its vertices.
