To make object snap work on BlockReference entities you can get the nested entity by using the Workspace.GetCrossingEntities() overload that accepts the accumulated parent transformation as a parameter, and then transforms the resulting snap points with the accumulated parent transformation. You can check this approach into the GetSnapPoints() method of our DrafingDemo sample.
