You are right, designfoil is only a computer wind tunnel and wing analzing program. I think what you are talking about could be done with the r/c design program that I also have ,called RcCad.It will do the root and tip rib ( you still have to do a little search for the right airfoil though )and then you can place ribs at any interval that you want in between and then print them out to paper along with the full size wing plans .You can also do the same for the fuse.You just insert a bmp or jpg of a 3 view drawing and move the rccad model lines to fit the 3 view and then press print and it makes the fuse plans and all the formers.
You can download a trial vesion at :

The price of the full program is only 49.95.I used it this last time on my scratch built V-22 osprey and really liked the way it worked.
Good luck
