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.
I submitted that rib shape to shapeways just to see what they would charge. What a ripoff. They wanted $32.00 for it and didnt even have a way for me to verify dimensions.
My plan was to print some ribs and then fill with 2 part foam, sand to shape and cover with fiberglass. It looks like it's back to kinkos and a copy machine as my wing building method.
Oops, maybe this will help. I attached the background image in case you need it. Also, it's actually 2 nurbs curves, one for the top and one for the bottom of the foil.
Thanks, Ellison. I made a wing earlier using mesh, but I've got a long way to go to work a spar in. Your extrusion of the nurbs got me thinking. It'd be cool to print a hollow wing in nylon and then fill that with 2 part foam to make it rigid. Maybe add a carbon arrow shaft as a spar and then fill it.
Ellison, how did you extrude the curve? I tried and all it does is move the curve like I did a grab. That was probably why I converted to mesh.
