Ciao Lia,

Hi Olaf,
in stt/PndSttMapCreator.cxx I retrieve the geometry of the TGeoTube, but the very starting point is the list of FairGeoNodes from the PndGeoSttPar...
The code does:

FairGeoNode *pnode = (FairGeoNode*) geoPassNodes->FindObject(tubename);
...
TGeoVolume* rootvol = pnode->getRootVolume();
TGeoTube *tube = (TGeoTube*) rootvol->GetShape();

...I don' t know if this may be helpful...
Lia.

As I read, this is specific for STT (I need something general) ... and in your example it seems that you already know that you're looking for a tube. So I wonder if

TGeoVolume* rootvol = pnode->getRootVolume();
TGeoShape* volshape = rootvol->GetShape();

would work in your case, giving TGeoTube as shape name?

Thanks
Olaf.
