Assuming 2D here, too.
TAKE A PICTURE (slide film) project it on surface at size wanted and
trace.
TAKE A picture (digital) and have it translated into an AUTOCAD format
(Meta file?)
how Nakashima handled things
Ho boy!
At any rate, the picture idea should work. It would give you a perfect
outline of the stump andcould be projected onto whatever you are
cutting the base from to outline the cut line at any size. I believe
you can have a digital image transferred to a 35mm slide and you
should be abble to find a old slide projector some where (library, God
Will, Salvation Army, Thrift Store, School

Can't you be a little more specific? Is this a 2d shape? Is it a concrete
object, a drawing, or just an idea?
Assuming 2d drawing, overlay a grid. To scale it down start with a finer
grid and just transfer curves in each grid cell to its corresponding cell in
the finer grid.
Without more info there aren't going to be very good suggestions.
Assuming it's not a 2d drawing, use lasers, expensive computer hardware and
software, and a highly trained consultant.

I'da said "any useful" suggestions, but that's close enough.
Garbage in, garbage out. OP - always give details, lotsa details - if
you actually expect any useful answers, that is.

OK, Sorry. I should have given more info, didn't want to bury you with
details. I have a slab cut from a tree. It's about 30" - 36" across and has
a very interesting shape, Imagine the petals on a flower, except irregular.
I want to make a coffee table out of it and I'm think about the legs or
stand for it. I don't think regular legs go well with this kind of thing,
and I've looked at how Nakashima handled things like this. I had an idea
where I would use a second slab from the same tree as a stand. I'm trying to
figure out how to carve a similar shape into the stand so it mimics the top.

Well... let's see.
One implementation of an integral is an area under a curve. So, your
surface is made of lots of curves. Do a curve fit analysis and find
curves with high correlation coefficients and add all the areas up.
Then, reduce your X and Y components using the lines given by the curve
fits so your equations are proportional to the original but have a
smaller area.

Thanks, some good ideas. I was able to download a program called Paper 2 DXF
1.0 at download.com. It turns digital pictures into Cad files. Worked great
.
