geometry viewing problem

hi all,

i am perplexed about a geometry

i have a problem if i should subtract surrounding vacuum from each
volume or not. when i do it it takes a huge time. to overcome time
consumption i surrounded detector with another region and subtracted.
but now the problem is viewing ZX plane.

when i plot it from XY plane everything seems ok but for ZX plot it says
"plotting region is empty"

could you please check the geometry file...

any comment would be appreciated
