I am looking for a way to merge/append to the same canvas two GDML geometries. (same reference frame)
Basically I have “Geom1.gdml” and “Geom2.gdml”, but when I do TGeoManager::Import() my previous gdml is deleted. (As suggested by the documentation.)
Hi, this is not possible. ROOT geometry is handled using a global pointer. Also, drawing attaches a 3D viewer to the pad that can handle a single geometry at a time.
