Neither does B3D.
My great idea was to convert a deck blueprint into a silhouette and use 
that to create a thin heightfield. which I could use as a template for 
the cross section of that level.

Aye, there's the rub.
Years ago I blagged a job as in Instrument tech on the oil rigs. In our 
crew was a Plater who prepared metal sheets for the welder to join. He 
explained some of the processes carried out in a shipyard. Marks out, 
from drawings or templates, shape of plates to be used in making the 
hull plates. Carries out machine processes by which they are cut, sawn, 
straightened, bent, shaped and fits up in readiness for riveter or welder.
Quite a job indeed. :)

Just a bit. :)

I would be if I knew what to do with them. ;) I missed the introduction 
to matrices at collage and never caught up.

What I would really like is a series of cross sections from bow to 
stern. Then, I think, I could use Blender's Nurbs.

Well, what do you know?
Have you seen this page?

Which is annoying as life is too "interesting" just now to start a major 
project.
