Re: TGeoXtru class in VMC

 Thanks Ivana.

 If VMC can handle that shape, I think that many  experiments would be interested in using that  capability. There are number of crystal ball  detectors that are geodesic break-downs resulting  in irregular hexagons.

 Can I be pushy and ask you what would be a time  scale (several months or ...?) for inclusion  of TGeoXtru class into vgm?

 Also, one more question. From your and a few  other emails I received I realize that I don't  understand the inner workings of VMC with  G4/G3/other MCs. In my concrete case, TGeoXtru  class - extruded polygon, is defined in ROOT,  but not in VMC and Geant4. In order to use that  class in Geant4 via root->Geant4 translation,  is is enough to define that shape in VMC, or  this class also has to be part of Geant4?  Looking at your example vgm.2.07/examples/E02  I thought that my geant4 code would run if  TGeoXtru class is defined in ROOT and
 vgm.2.07/packages/Geant4GM/source/solids/  and that something like G4Xtru class is no necessary?
