save as / export might only produce pixelated results, you might have to electronicly trace the logo in illustrator to make it scale friendly. learning the way vector paths work in illustrator might be helpful. I'd find CAD hard. my asumption is that cad works like a graphics / drafting geometry set with a compass, set square' and such. I kinda applied those principles to make the logo provided ^^^ because of my limited knowledge of illustrator, I had to work in freehand for connecting 'stray' lines, to make the nautilus spiral connect. BUt do not fear there is help out there, even some of the 'pen tool' advice in our archives is vallid.
