Slant six intake manifold flanges, anyone got a cad file?

Take a gasket to a community college CAD class and have a student do it up. My sis could do it but getting her to actually do it would require me to go over there and drink beer, and sit up on the roof patio 3 blocks from the beach, and probably go back under her 560SCE and see why her A/T wont go into D.....You could probably do it with some free CAD programs. I think you would just need to:
make a rectangle with polar coordinates (easiest) ,
then chop and radius the corners,
then do same for ports and clone them with a known offset taking into account that the offsets are different in the middle,
Then cut them up
its almost easier to draw it on a drafting board with a T-square but you cant get that into a DWG or DFX file....
