I don't know if we understand each other. As I understood from de L3P
manual, some primitives from the P-dir are substituted by L3P to POV
primitives. If you take a look at
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=152159 (where the new panels
are used) you will notice that the circels are now round, and not, as in my
version, 18-sided.
Let me get this staight: I don't want to sound as a know-it-all!

I understand, but again, I don't understand or know which primiives are
available and what they are used for.

Thanks for the feedback!
