Sorry it's taken awhile for an update, I was going on a weekend trip with my family, and couldn't work on the plane.
Anyway, I've finished the wing (pictures coming soon), and I wanted to do a little experiment. I drew up the plans in Fusion 360, and then imported them into Meshmixer, which by now I've pretty much figured out (there were some troubles with bad mesh construction and unit scaling) unwrapped them, and compared them to the existing skins I have.
Here are some pictures of the process:
You can expect the text version of a CAD/unwrapping tutorial on my website and the forums soon, since I actually know what I'm doing at this point.
Now I realize that it actually takes about the same time to make plan in Fusion and Inkscape, sometimes less depending on the complexity of the model, and in the future I might continue to use fusion depending on how the new skins fit. (if they don't I might just use it for the internal structure)
