Re: arc or curve fitting program

Hello,

I've got the formula in a few different geometry and cnc books, but
they are one place, and I'm at another. If you still need it, I can
post it tomorrow...

BTW, I tried a few inet searches: "three point arc" came up with
basketball stories! There were also a few on the math sites using
matrixes, but I think you're looking for the "simple" way...

There were also a few that strange enough had to do directly with
toolpath and cnc; one was a patent description for a way to better
implement CVV.

Let me know if you still need this,
