I've been playing with Carlson's Sailform program, trying to make a F14 mainsail. I don't quite understand all the options in this program and would like someone knowlegeable to review my design.

Where is the design made available ? I would love to se your design and discuss ideas..

Have a look at Sailcut as well, http://www.sailcut.com

Sailform did not run on my WinXP system. I think this is some quite old software, so I will have to tweak it a bit to make it run.

I'm running WinXP Home and it seems to work fine. I can't seem to get the VRML or some other little features to work, but I think I'm missing some little add-on for those.
PM me your e-mail address and I'll send you the file, catsailor doesn't allow anything but pictures to be uploaded.
