I was trying to test the useful function TGeoManager::CheckOverlaps (or TGeoVolume::CheckOverlaps). I’m using ROOT version 4.04 – that is what our experiment group uses now. I made two Boxes, and deliberately put them in one TGeoVolume so that they are partially overlapped. Then I called TGeoManager::CheckOverlaps (as well as TGeoVolume::CheckOverlaps), but it returned with “0 overlaps”. Does it work in ROOT v4.04? Isn’t it designed to catch any mistakes in making a (e.g. detector) geometry system?
Thanks a lot,
