class TGeoBuilder: public TObject

 TGeoBuilder


   Utility class for creating geometry objects.These will be associated
   with the current selected geometry manager object:

      TGeoBuilder::Instance()->SetGeometry(gGeoManager);

   The geometry builder is a singleton that may be used to build one or more
   geometries.

 Divides MOTHER into NDIV divisions called NAME
