I have a feeling the PLOTS symbols are "flat" 
because you forgot to set a T3D keyword on the 
PLOTS command. :-)

I can't see any reason why 3D symbols with PLOTS
would be prohibited, even in PV-Wave, which I
assume you are using.

I think speed will be a problem using PLOTS. I'd 
offer you something in the line of object graphics
3D scatterplots, but I doubt it would apply. :-(
