Who would have thought doing a lisp for the above item would take hours and damn hours?
I have an all too convenient cold at the moment (this stops me from running/riding a bike/walking etc)-so I have had time to finish this one. I'm not terribly proud of the way I have written this one-no planning, just hack away until it was finished. Bring on object oriented programming for lisp (maybe that is what visual lisp is?).
The next steps might be to make it a bit more user friendly (it is all command line stuff).
I have given it to my friend who typically might take 3/4 hr to draw a window in 2D.
I'm hoping he can do one in 5 minutes using this one.
Another next step might be to do one for doors, then a quotation/costing/cutting list add-on, but this would be a real time-burner.
