OK, can someone briefly tell me why this doesn't work/isn't a good idea?

myLogicalVol->GetPhysicalVolume()->GetTransfomration()

myLogicalVol->GetMother()->GetPhysicalVolume()->GetTransformation()

... etc until the world volume ...

and then add the transformations?

This crazy; what I'm hearing is that the only way to navigate the geometry at construction time is to build my own geometry manager to track the placements of objects myself. Is this right? If so, isn't there a need for a generic tool of this kind?
