How to create lines drawings from a model?

lines equally spaced in between,giving me a matrix of 30 measured stations.
How is that any different to creating waterlines 10mm apart?
Well probably i would end up with many more points, but wouldnt the same problem prevail? ie the curves still not going through the stations.
What would happen if you treat all points as an edge? as if the hull has multiple chines, and then try to smooth them out? Would that be possible do you think?

oh i,m sorry this was a joke,about printing plywood!!
But how they make a model is they use the plan view of the boat, say they scaled 10 to 1 and the waterlines became 10mm apart instead of 100 on the true full size thing, then you would have the plan view of the boat at each waterline, , the model wood thickness 10mm, then you would cut this out on bandsaw or jigsaw and the the the next waterline down and so on you would then have all these slices, glued one on top of other, then you would sand the corners off, to make fair hull, the top slice would be your sheer height and plan,
