Re: TGeoXtru class in VMC

Hi Emil,
TGeoXtru is not included in VMC (nor in VGM) because is supported only by TGeo. It makes not much sense to include it because your code using it will not be able to generate a valid G4 geometry. Until we will have a working navigation in G4 using TGeo I am afraid you cannot use TGeoXtru in your G4 simulation.

Regards,
Andrei
