Question checkoverlaps in G4PVParameterises / potential bug 

Forum: Geometry
Date: 18 Sep, 2009
From: Evaristo Cisbani <Evaristo Cisbani>

I defined a relatively simple parameterised volume made of layers of identical surface but different thickness and material (to simulate a GEM chamber).

When I enabled the CheckOverlaps I got an unexpected overlap warning between two layers that are separated by several mm.

Looking at the code of CheckOverlaps in G4PVParameterised.cc (version 4.9.2.p02) it seems to me that the line:

G4AffineTransform Td( GetRotation(), GetTranslation() );

should be moved inside the "pos" loop, right before the definition of "md"

Does it sound correct ?

Thanks
