Dear Kevin,
I had the similar questions in the past and I found out answers from this
discussion
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/6806.html

There you can find modified MGDRAW example for boundary crossings:
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/att-6806/mgdrawBDX.f
These two things were really useful for understanding how to work with
FLUKA.
Cheers,
Viktor
