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 (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 ?
