It's still in the early CAD stages but I have the basic wing designed in Compufoil (figure 1) and exported the rib sketches to Soildworks 2005 (figure 2) to complete the final touches (landing gear, joiners, servos, etc).
Figure 1
Solidworks is a very powerful 3-D design program in which I can design everything down to the very last detail and once that is complete Solidworks can format all the parts in a laser cutter friendly format. It even can transform the 3-D design into 2-D drawings (for plans).
