Would TurboCAD Deluxe 11.2 be a good CAD program to use to design a teardrop? It's an older version that's $39.95 from http://www.cadandgraphics.com/tu11pr.html
Andrew's Grumman II profile looks good to me. I'd like to brainstorm variations of it on a computer. http://www.tnttt.com/viewtopic.php?t=15080
BTW, I'm a CAD newbie.
The web store above sells TurboCAD Deluxe 12 for $59.95 and TurboCAD Deluxe 14 for $99.95. If either one of them is significantly better I'd consider using one of them.
Thanks in advance for any help offered.
