Hi that is still the old release.
I have checked again, it works.
the problem was related with a bad copy numbering.
anyway if somebody tries to substrate two volumes by using
TGeoCompositeShape, pay attention because there is a bug in the root class documentation.
TGeoCompositeShape *cv = new TGeoCompositeShape("cv"," first\ second")
Don't use (\) for susbatration, it doesn't work.
The proper expression is (-)
TGeoCompositeShape *cv = new TGeoCompositeShape("cv"," first- second")
best regards
alicia
