Once you have the plate steel cut, then you have to bend it - hopefully
fairly precisely to match the other plates, all to be assembled into a hull.
I presume there must be a method other than trial and error.

Here is a webpage concerning cutting hull parts from thick plate:

and here is a picture of the pieces to be cut (but if they are doing it by
NC, why pre-paint the lines?):
