Unfortunately it looks like there is a whole lot more stuff to figure out than just that...

One of the biggest is that drawing a kind of loose approximate curve framework generates curve data and not necessarily solids or surfaces.

But it certainly looks like it could be cool for doing some initial sketching / visualization / concept type work.
