Summary0031871: Modeling Algorithms - Elaborate consistent shape validity criteria
DescriptionThere are many use cases when BRepCheck_Analyzer does not report any problem with a shape. However, if we look at the shape carefully we can see obvious problems (e.g. self-interference). And, in the result, such problems lead to failures when working with such shapes in the modeling algorithms.

So, the idea of this ticket is to elaborate consistent shape validity criteria and implement their checking in shape analyzer[s].
