The following classes have been removed as obsolete: - BRepAlgo_BooleanOperation - BRepAlgo_Fuse - BRepAlgo_Cut - BRepAlgo_Common - BRepAlgo_Section The corresponding classes from BRepAlgoAPI package have to be used instead. Draw commands: - fuse - cut - common - section/psection have also been removed as obsolete. The corresponding commands for modern Boolean operations algorithm (bfuse/bcut/bcommon/bsection) have to be used instead. Adjustment of the test cases to use the commands for modern algorithm.
