I'm not sure you will be any more enlightened when Ronn's
book arrives, at least with respect to how to do this with
an iTool. It's fairly straightforward to do it with object
graphics, however. In fact, we were having this discussion
just a day or so ago in a thread entitled "3D plotting".
The example I showed used a Rick Towler object named
RHTgrPSolid to produce a 3D tetrahedron that I used
as symbols in that scatterplot.
Cheers,
David
