Defining components in a geometry imported GDML file

[Guidepast]

I’m working on a Windows machine, I would like to ask you how can I
define a radioactive source volume as a source of particles and a detector with a geometry imported in a GDML file, since it is constructed by FreeCAD.

Thanks a lot for your help.

a detector with a geometry imported in a GDML file, since it is constructed by FreeCAD.

I think you can take help from the link given in this question.

B1 with GDML import - can't change gun location

I modified the basic/B1 example to load a GDML input geometry. For the interactive method, I am not able to change the gun position to the “Tracker” volume located behind the lens of the example telescope gdml input file. You can clone my project with git clone https://github.com/swissco67/B1dose.git An interactive run will require to provide the gdml input file like …/B1dose-build$ ./b1dose Sample1.gdml Also not sure what’s wron to get a crash for the batch mode run?

it is also doing same that how one can import a geometry in Geant4 that is made by FreeCAD and also you can take help from
Geant4/geant4.10.07/examples/extended/persistency/GDML/G01.
I think it can help you.
