created in class BRepBuilderAPI_MakeShape to fix all tolerances of the shape and it's subshapes by the tolerance rule: vertex tolerance >= edge tolerance >= face tolerance. Edge or vertex tolerance which does not satisfy the tolerance rule will be increased. Draw command EnsureTolRule was created to test new functional. Tolerance post Build (Perform) fix was made for: - BRepBuilderAPI_Sewing, - BRepFilletAPI_MakeChamfer, - BRepFilletAPI_MakeFillet, - BRepOffsetAPI_MakePipe, - BRepOffsetAPI_NormalProjection, - ShapeFix_Shape, - ShapeUpgrade_ShapeDivide.
