- BRepBuilderAPI_Sewing, - BRepFeat_MakePrism, - BRepFilletAPI_MakeChamfer, - BRepFilletAPI_MakeFillet, - BRepOffsetAPI_MakePipe, - BRepOffsetAPI_MakePipeShell so that input shapes remain unchanged by the fix. Tolerance post Build (Perform) fix was slightly changed for: - BRepOffsetAPI_NormalProjection, - ShapeFix_Shape, - ShapeUpgrade_ShapeDivide. Correction of tolerances in input shapes was made for tests: - blend buildevol F9, - complex B6, - B8, - D5, - E2, - E4, - E6, - E9, - sewing tol_0_01 G3, - G4.
