Well......

Most 3d drawing files are nothing more than a point source and a vector for each line.... ie rays. Graphs are nothing more than equations, and if you start with x=1 and keep going from there, you have a ray, sorta.

So it would be merely a function of converting equations to the correct format for a CAD program to read.

But, other than pure curiosity, why?

And by the way.... google is your friend.
