Re: Question Volumes of G4Tubs smaller? & Boolean operation between to 'ring's not working? (Kazuyoshi Furutaka)

1. G4Tubs seems to produce discs/tubes with smaller volume than expected.

In 7.0, the volume printed by /vis/drawTree is the volume of the polyhedral representation. That explains the small difference. From the next release it will use the newly available GetCubicVolume method of solids, which is more exact.

2. It seems that Boolean operations (G4UnionSolid/G4SubtractionSolid/ G4IntersectionSolid) don't work ...

In my experience, Boolean operations give an error if the two volumes do not intersect, i.e., if one is wholly inside the other.
