The scene has no extent

SEMOutput.txt (4.8 KB)

Dear John,
I have attached the output from the program that you requested.
Discussing with colleagues, we were wondering whether a way forward would be to abandon the .GDML file approach and (for the moment) build a new DetectorConstruction from scratch. Currently the model is very simple, just a thin film of material with a planar detector above and another below. We would like to simulate the situation where a metallic needle is brought very close to the sample surface and a potential is applied to the needle. Another situation would be to simulate electrons passing through small nano-particles. (This might be in association with higher energy Geant4 codes). This second application would certainly need a new DetectorConstruction.

Hi Chris
OK. Looks like the geometry hierarchy is all in place. But why the extent is null is still a mystery.
Yes, I agree. Write your own detector construction. Your project sounds interesting.

Hi John,
Thanks for all your help. Maybe in time the extent issue will get resolved.

Best Wishes
Chris
