Re: Question Does the copy number of a parent volume propagate down to the daughter volumes? (Dale A. Prokopovich)

I'm not really an expert on geometry but your posting caught my eye. The quick answer is, No.

But there does seem some confusion. When you place a daughter in a replica, it appears in each replicated part. Similarly a G4PVParameterised, which is a G4PVReplica by inheritance. Similary, grandaughters appear in each replicated part. If they are the sensitive volumes you are interested in, you have to get the copy number of the replica from the navigation history. I can't remember in detail how to do that but it's well documented in the Application Developers Guide and I am particularly impressed by the tutorial presentations - look for tutorials on the Geant4 home page and find the presentation on Detector Sensitivity.
