I'm pretty comfortable taking an existing profile and adding the right ribs, infrastructure, etc to make a good strucutural build. To date, I've mostly done it with a ruler and some french curves. I don't have any formal training with drawing things - just a general understanding of what the result should look like. The structural aspects of building are my strength. Then I have to nurse my work through the finishing stages. Thanks for bumping this to the top. Chad, If I were willing to invest up to $1K in a CAD program, what would you recommend?
