TGeoXtru class in VMC

 Hello VMCtalkers,

 I have a question for ROOT/VMC developers.  I am re-writing my groups detector simulation  from Geant3 into Geant4. The best/most readable  option would be to use the TGeoXtru class that  is available in the current Root release.  (Our detector is a geodesic break-down
 of sphere with regular pentagons and irregular  hexagons, that can be modelled as extruded polygons.  The alternative is more cumbersome - making  a single irregular hex out of 6 general  trapeziods.)

 But, as I can see, TGeoXtru geometry is not  yet included in root/vmc/src/TGeoMCGeometry.cxx  nor in vgm.2.07/packages//RootGM/source/solids -  when I try to interface my detector.root with  geant4, error results:

VGM info: Importing shape: TGeoXtru

    RootGM::Factory::ImportSolid:
    Unsupported shape type (shape 'TGeoXtru") *** Error: Aborting execution ***

 So, my question: are the additions of new  primitive solid shapes coming soon to VMC?

                     Best Regards,
                     Emil Frlez
