0030346: Modeling Algorithms - BRepPrimAPI_MakeRevol throws "BRepSweep_Translation::MakeEmptyVertex"

Browse Source 
Implementation of method "IsDeleted(...)" for MakeRevol and MakePrism algorithms.

Problem (exception) occurs during history building and was caused by an attempt to obtain generated shape for subshape, which was really "deleted" by algorithm - this input subshape and its possible generated shape was not used in result.
