It would gave been better if you had posted the link to the thread. That 
way the answer might be in it. Or at least a good clue.

What you will want to use is the trace command to find out the distance 
to the object below. You also might want to use min_extent & max_extent 
to return the minimum and maximum coordinates of a #declared object's 
bounding box. ( <-- straight from the help file :-) )

It is not trivial what you want to do, btw.
I am sure you will get help here in the form of general pointers to help 
you work it out. :-)
Remember your evil professor may be reading this thread. ;-)
