Hi, I'm new to the idea of 3D in general but I see it's power. I've been playing with Blender 2.6 and know just a little and not enough yet. Anyway, I want to print airfoils and a spar to hold them. I took an airfoil from Xfoil and used it as a background image, then followed it with a Nurbs path and converted it to a mesh. Then, I used fill and F-gon to make it solid.
What I want to do is figure out how to "cut" a slot for a spar or even how to cut some lightening holes. If I can do that, then I would build a spar to fit and curve it for dihedral like on the easystar, and the printed ribs would snap in place.
