0031 // This class tranforms G3 divided volumes to G4 replicated volumes.
0032 // UpdateVTE() method checks parameters of mother volume
0033 // and in case they are complete the solid that will be replicated
0034 // is created. In case of division with offset an additinal envelope
0035 // VTE (G3VolTableEntry instance) is created.
0036 // CreatePVReplica() methods creates the G4PVReplica instance.
