Hi guys,
Just wondering if any of you guys know of any computer software that lets you design a 3D airframe. Also would i be able to print these designs out so i can scratch build it or are there CAD cutter machines out there that i can use instead of having to scrath build it?

No problem, go on over to scratch building and CAD Design and there will be people there that can help you out. I have several sets of plans that were sent to me by email and then I had them printed out.

Compufoil is a pretty easy to use program for wing design. I also have Delta-Cad which works good and doesn't cost much. I wasn't happy with the Model-Cad software sold by Tower Hobbies though; too many bugs. I'm no expert on this stuff though, you may want to check out the scratch building and design forum.

I use Profiliv2 for wing design and alibre design for 3D CAD modeling. Very happy with this combination.

Also, there is DevCAD available and next version promisses a full parameterized fuselage design. Have to see this.
