|Summary||0025249: Some problematic cases from mesh tests have been uncovered during refactoring of BRepMesh|
|Description||During refactoring of main classes of BRepMesh package performed in context of 0023106 some bad cases have been faced during testing campaign.|
Attachments contain faces extracted from that cases. In general, these shapes seems invalid, however BRepMesh should try to fix some common problems on its level to produce mesh anyway.
|Tags||No tags attached.|
|Test case number||bugs vis buc60858; mesh standard_incmeshV4,C9; omf advanced_meshfuse ZD4|

Problem described in issue is reproduced on current state of OCCT.
All cases provided in context of this issue are invalid, e.g. contain wires with gaps covered by vertex tolerance, problematic geometry or topology.
However, the most of the cases attached here are meshed anyhow on current master with several exceptions.
Please make a decision regarding this issue, should we consider that the goals have been achieved as much as possible and close it?
I agree with conclusion about the tests bugs vis buc60858, mesh standard_incmesh V4.
But the test mesh standard_incmesh C9 is bad and TODO refers to the closed bug 0023105. If the problem with free nodes is inevitable with such input shape then we should mark this error as REQUIRED.
