Hi all
Using lisp, how do I break down the list of x, y and z coordinates given as the centre of a circle? I have isolated the list with (setq cen-pt (cdr (assoc 10 b))) which gives (168.077 168.62 0.0), but I can't remember how to extract the x, y and z elements?
Long-long-time since I looked at this stuff :)
TIA
Phil
