Isn't that what is already prepared, with full-scale plans ?

Fairing lines to a scale on a drafting board or a sheet of plywood, it
"lofting the lines".

Full scale is the only way to do a full loft. Sometimes in a very large
vessel the loft will be to half scale so it will fit on the loft floor. The
main objective is to get the mold station to produce fair lines on the
finished hull. Adjusting the molds, after the fact is not the correct place
to find the errors.

I know that the OP was about a 16ft canoe. However the reason I jump in
about using a full loft is because so often a first time builder will look
for any reason or recommendation to skip the full loft and get started
turning wood into a boat. Unless the designer has taken the results of a
full loft (or the computer equivalent) and done the correction to the table
of offsets, then the offset table should only be trusted for the full loft.

Year , -- but meanwhile the measures must be transfered onto the material,
as the cut materials make up the actural hull. I mean you make the plans to
be able to show the lines not on paper, but on the materials so they can be
shaped into an assembly , ------- then with a heavy frame that must support
a panel , there will be a gab , unless the frames are marked with changing
angle both sides.
--------- Realy the spline for me ,alway's was the spline you place ontop
the rough timbers, before making them follow the planking some 90 pct. Realy
isn't this a bit old fasion, when you can shape the whole framework from
sheet material. Ever tried placing an oak frame in a Baltic trader ? --- if
so you will know there are a need for better technology , did you ever use a
vaccum cleaner to remove a rotten frame ? -------
Anyway first upscaling , then transfering must be less accurate, than
acturly producing the actural frame ,cut directly from the computer
drawings. This also allow for accurancy that make things possible ,that is
more difficult or somtimes impossible with tradisional means. Like forming
whatever assembly framework for whatever shape hull, in only sheet
materials.
