| Summary | 0029922: Boolean operation with conical argument loses degenerated edge | ||||
| Description | Apex of cone (and the degenerated edge) is a common part of the arguments of Boolean operation. However, after Boolean CUT one image of the conical face does not contain any degenerated edge (but it must contain). As result, this face is geometrically not closed in parametric space (this gap is covered by the vertex) and cannot be triangulated by BRep_Mesh OCCT-algorithm. P.S. Possible reason of this bug is in big tolerance of the source cone vertex (in the Apex). If we reduce this "apex tolerance" then the result of Boolean operation has become correct (see Test bugs modalg_7 bug29807_b3b). | ||||
