Even the iTools, which are supposed to be 3-D graphics utilities,
only support 2-D plotting symbols by default. You can provide a
custom symbol with the SYM_OBJECT keyword, but it is a struggle for me
to figure out how to do that. A beginner would be clueless.

I submitted a formal request to ITT to add the Platonic solids plus sphere
as default plot symbols that could be referenced by index (without
having to make your own object), but that obviously didn't make the cut.
