As a matter of fact, it should be possible to use *ANY*
kind of symbol you like, including 3D symbols (e.g. little
shaded spheres), since the "value" of the DATA keyword for
the symbol object can in fact be another model object. (Or so I
am told by someone who should know.) The model can, of course,
contain any valid object hierarchy.
I may not have a chance to test this, since I'm off to
Europe today to teach an object programming course. But
you can bet that by the time I land on the other side of
the pond I'll have a new programming exercise for my
class. :-)
Cheers,
David
