If it were only that easy. Ive thought about it a bit and the best I can
figure you need to start by creating a three dimentional matirx that has
rediculous floating point resolution that is essetially boundless. this
way if you want 1" lines spaces 1/8" apart over say 15 miles you can
store this geometry. then once you get a handle on that then you have to
be able to create, place, store, and recieve basice geometry; line,
circle, arc, etc... Then comes the easy part you neet to be able to pic
any perpective relative to what you have created and stored and
represent it in two dimentions on a display. Piece of cake and first
year basic programmer can do it. Seriously if it were easy AutoDesk
wouldn't be so huge. They are not gonna tell us how they figured it out.
Coding it isn't the problem its figuring out how to do that is complex.
