Hi all, hi Tobias,

I tried a small simulation with the root geometry containing the geometry from the CAD file (Feb. 2008). I get the following segfault from building the geometry:

Well It doesn't tell me much. Maybe the file (preliminary state) is broken.

Actually I just saw that in this new geometry file exists a TGeoManager as top level object. So the call for the TVolume is not valid. I'll look for a workaround...
