As an engineer who's worked extensively in both kinds of systems 
(primarily designing microcontroller-based circuit boards), and a 
programmer who's stolen useful ideas from endless amounts of other 
people's code, I'll say only that I disagree with your implication that 
looking at PythonCAD will give him no useful ideas whatsoever about how 
certain aspects of CAD programs could be handled.  PCB layout programs 
do, after all, have to do the basic work of displaying circuits (which 
as you know are generally shown as 2D drawings).
