Don't create data structures for whole set of faces. Necessary structures are created directly in BRepMesh_FastDiscret. Don't copy nodes data during scaling, single structure is used. Remove lines used for debug Fix sphere: resolve problem came from merging. Keep code clean - remove unnecessary logic, expected to be used for complicated restoration process. Test cases for issue CR25364
