I used autocad and ended up creating points, then snapping a nurb (spline) to each. The end tangents were plopped freehand to fair each end of the curve. If you use this technique, avoid snapping the nurb to points that are excessivly close as decimal roundoff causes some really wierd lumps in the nurb. Worked great for me, doing all of the Auk forms and plotting in around 2 hours. Having just launched the boat (Yea, somone on the board really finished one!) I really don't think a small error in the form will ever be noticed. If you don't believe me, just strip the hull, pop the staples, then shine a flashlight on one side of a form and look at the gap to the strips on the otherside, pretty scary.
