Hi Xiaosong, that should return you the copy-number of the mother volume at the current level. As that call goes through the touchable, it should correspond to: theTouchable->GetReplicaNumber(1). Remember that, apart for replica and parameterised volumes where copy-numbers are generated by Geant4, for placements it is your responsibility to assign the copy-numbers (Geant4 does not make use of them internally in any way) and to interpret them in hierarchies of volumes which are placed multiple times!
