It's even worse with a pencil. You can draw a blivet. I don't think
you can print one in 3D:

I found some good textbooks written to train the flood of new aircraft
and shipyard workers at the start of WW2. They differ in scale and
materials and tools but not much in the basics of turning flat stock
into 3D curves.

Scribing and torching a preassembled 300 ton superstructure to fit the
curving deck is a little beyond hobby work.
