using gimp as a CAD program, kinda...
K, so i have decided to design and build my own longboard, so i have decided to try and use gimp as my design software. I am trying to make the deck have almost a tear drop shape, 3.5 feet long, 10 inches wide at the widest, and 1/2 an inch thick. I know what i WANT it to look like, but i want to put the pattern on paper so i can run out to kinko's or something, print it off, and lay it over the veneers after i have them pressed together so i can be confident that it will be a consistent and evenly ballanced. All that i am having trouble with is how to actually put out the design in gimp. could you guys give me tips on how to effectively use gimp as a kind of blue print program? any help would be awesome. or if you are board (miss spelling for the pun), i would even love to accept any designs that you guys could whip up. thanks a bunch!

CAD is mostly line graphics, so InkScape (Gimp's cousin for vector graphics) would be a much better choice.

If you want to stay with Gimp, you can use the Path tool (Path) for the same effect (but not with all benefits of vector graphics), namely, draw nice smooth and regular curves.

Look for tutorials. The learning curve is a bit steep a the beginning, but very much worth it. The trick is to use as few points as possible, there are six points here:

The Path tool generates Bezier curves. Bezier was a mathematician working for a French car manufacturer who found that these curves were ideal to design car bodies. They have become a standard in computer graphics (fonts are mostly a set of Bezier curves).

Note that Inkscape deals wit the very same type of curves and would still be a better choice (you will be able to scale up printouts to use them as cutting templates).
