OK you can find my code and some images again at

I did perform a subtraction of two solid spheres to make a shell like you asked and interestingly, they did not work (the photons passed right through, see However, once i performed an intersection with a box to pull out the part that I want for my simulation, it worked!!! (see

Then I performed the same thing using two ellipsoids instead of sphere. The result after the intersection was NOT the same (see

The code is posted there as well. The lines of interest are 433 to 477 in the detector construction.

Thanks Again.
