Hi Dan--
I'm a newbie to, well, pretty much everything--teardrops, carpentry, Sketchup--and I just wanted to thank you for your excellent and thorough youtube series on SketchUp. I spent all morning trying to figure out how to translate the Grumman's curves into SketchUp, only to discover that you had already done it. I've learned a ton from your series. I'll try making my own from scratch following your instructions, and if I can't make a go of it, I'll edit (mangle?) your file instead, which should get me where I need to be. Thanks so much!!
