Re: Question Problem with subtraction of two polycones (Jerome Roccaz)

The boolean processor for visualisation fails because one volume is entirely inside the other. This is not a situation that should happen. To get what you want simply make the smaller volume a daughter of the larger one; the Geant4 convention is that the daughter replaces - and hence effectively subtracts from - the volume of the mother. The mother has the material of the container (iron, say) and the daughter has the material of the interior (air, say).
