If this a stitch and glue type boat...
Rhino would work for this but I'd use the offsets as reference points only. If you limit the number of control points of a curve to 3-5, Rhino will produce a fair surface from those curves. There are limts to that of course. When you make a curve or surface in Rhino (and similar applications) the fewer amount of control points you use, the fairing the curve/surface will be. Set up the offsets and then redraw the curves and re-position the control points so you get close, but don't force them to match perfectly. Rhino does a nice job forming "natural" curves. -- Matt Langenfeld JEM Watercraft http://www.jemwatercraft.com Stephen Baker wrote: James says: try the free download of Rhino. (Google for Rhino 3d) snip ... but I Would never work without Rhino I use Rhino every day, but would never try it for this purpose. The shpaes produced are just not fair. For a quickie guestimate of numbers, it may be fine, but that is it. Here's an example, kinda... I found this old lines plan in a book by Phillips-Birt: http://www.boatdesign.net/gallery/sh...ize/big/sort/1 /cat/500 After 2 hours with Rhino and a tracing program, I had something that looked right in profile, but had a surface so unfair that you could see the "planks" where Rhino had tried to fit a surface. Two more hours in AutoShip, woring "off-surface", it had faired into this: http://www.boatdesign.net/gallery/sh...ort/1/size/big /cat/500/page/ I'm not going ot kid you that those lines are exact, but they are extremely close. Eventually, my imagination got the better of me and I stuck on a deck and rig: http://www.boatdesign.net/gallery/sh...ort/1/cat/500/ page/1 With just Rhino, it would be another "failed project" on the back-burner.
