Re: None Combining overlapping parameterisations (Marcus O'Flaherty)

Hi Marcus,

you cannot mix two different parameterisations in the same mother volume.
For your case, you either use normal placements or adopt G4AssemblyVolume,
so to drop each imprint inside the same mother (assuming there're no overlaps).

Hope it helps!

Cheers, Gabriele
