Hi,
Does anyone know of an open source program to fit points to an arc(s)?

are you looking for something that does spline fitting (autotrace comes
to mind, but I would not necessarily trust it off the bat), or are you
looking for something that fits circle arcs?
The one thing I can think of off the top is that there was an old NURBS
to bi-arc converter that was integr
Perhaps explain what you want to do
a google for "curve fitting algorithm download"
brings up a lot but curve fitting is a minefield so many ways

Googling: fit points to arc of circle
gives lots of hits. The ones I looked at seem to give a least squares
fit of data with random noise.
I don't think that is what you are looking for, though.

I have code I can put a license on. What exactly do you want to do?

The idea that there is no such thing as objective truth is, quite simply, wrong.

As soon as I hit send I knew I should have been a bit more
explicit. ... we're supposed to learn something as we get older. Ha!

Actually if you have

Like the other respondents, I wonder just what it is you want to
accomplish. It's hard to point to a solution without knowing what the
problem is.

I used several tools when i looked at EDM crater depth vs joules of
energy applied
these were all linear regression tools
but first it was easier for me to work inside the framework of a spreadsheet
with the xy data pairs plotted,
then analyzed
maybe this will help
use openOffice Calc
and yo

sorry i didnt grok that you wanted g2/g3 arcs
I rememebr Ed Vilchez of AGie reducing huge gcode files of tiny lines
to lines and arcs
all done on one of those HP 9830 cassete based computers, in LISP
technically a great filter, but it ended up being used to create the
"BJ" stainless cutout on
If you cannot find anything else, I'll dig around in some of my CAGD
code from when I took Farin's class and see if I have anything useful...
