New Revision: 1509

Modified:
   cgm/trunk/geom/OCC/OCCBody.cpp
   cgm/trunk/geom/OCC/OCCBody.hpp
Log:
for moving/reflecting etc. funtions, OCC operation gives a new
object, need to update for body/lump of their underling CompSolid/solid. now crashs at lump->set_TopoDS_Solid(TopoDS::Solid(M(i))); need to investigate.
