For references, similar topic touched upon in this thread
how to make ship / boat's paper model pattern?
Posted my own thoughts on generating hulls and fuselages on Blender, hopefully sufficiently generic to apply to any 3d software
Blender hull/bulkhead generation part 1
and part 2
and another article to help understand how to section the parts so that they can unfold flat and in as large a single part as possible when dealing with curves
Rounding out flat paper
The only thing about the first 2 articles is that I've learned more about how to use Boolean operators and layering multiple objects to carve these models which is particularly useful when trying to fit protrusions such as shafts or tunnels through these rounded shapes. Basically, software can make this process a lot easier.
