Trace one block onto the next with charcoal then sand it down over a few weeks because it's not like they had anything better to do back then.

Look at the OP pic, how do you trace with charcoal along 2 dimensions? It's parabolic in 2D, parts in the middle of the cut would NOT correspond to any of the charcoal marks you could make on the surface

You can project on two perpendicular planes and still get the 3D shape right. Have you made anything with your hands, ever ?

That's my point. You're not talking about cutting straight down from the surface markings. You can't do that.
Would you mind explaining the exact process here? You can't cut straight down. You're cutting along one direction modulated by the curve you drew in another. But I guess that's an easy task for primitive humans with stone tools?
