Good morning, and congratulations on a very pretty and slippery design!
Your design thread answered the primary question I had today; is Fusion 360 a good package for trailer design?
More specifically, we're designing a larger streamliner, and need to create a male mold & batten structure to form the shell around. Do you feel that Fusion 360 makes it fairly trivial to create compound curves? Would we be able to specify a shell thickness and reduce the mold dimensions by that amount so we could have the molds CNC routed?
The front of the trailer will be flat panels coming together and edge-joined with radii similar to yours, while the back will taper following a few different and much more complex curves.
I could haul out Skene's "Elements of Yacht Design" and draft this by hand, but I think I should stagger into the current century finally and learn something a little more modern.
Also, check out our build journal and steal from us all you'd like. I'm thinking specifically of the honeycomb floor and bonded "frame", which would save you work, weight, and complexity. Also, the torsion axle with radial tires is wonderful!
