Summary0033314: No triangulation of cone face
DescriptionWhen loading a step file one of the faces (a cone) cannot be triangulated with
BRepMesh_IncrementalMesh e(face, 0.01, true);
triangulation = BRep_Tool::Triangulation (face, loc);

after saving this face as a step file and loading again a different brep representation is generated that works.
The 2 different breps are attached.
Steps To ReproduceLoad both brep files, one can be triangulated like above, the other not. The working one is created from the failing one by saving as a step file and loading again.
TagsNo tags attached.
