Foam wings don't require CAD drawings for every rib and neither does sandwiching balsa rib blanks between templates and sanding the stack to shape.

Back when Eppler's airfoils were coming out and "new" airfoils were the rage, I used to make wings for my test mule glider to see how the modern profiles flew. Rubber band on wings had their benefits. Going from a root E205 to a tip E198 was no problem at all for example. And didn't add even a minute to the building time. During the couple of years I did those tests, I'd knock out a wing a week. They were 2m of course. The one step that took the most time was covering. No extra time at all to plot out each rib. You only need three templates for those poly wings, root, break, and tip. All the in-between airfoils show up when you sand the stack of blanks. No computations needed.
