Gene
do you want to convert a series of short lines that approximate arcs
into g02/g03, to save space?
Or, described as 'fitting x y pairs to a circle'?
Dave E was looking for similar ( a good while back) and I didnt find any.
If you have slices that can be processed in scripts with librecad (lua)
or esdxf(python)
I imagine some batch processing, layer by layer, slogging thru your
megafile )
For python fitting a list of coords to circle there is
https://scipy-cookbook.readthedocs.io/items/Least_Squares_Circle.html
There a classic solution by Coopes but all the papers and code I've
found are pay for.
( I hate those 'services; that charge for such information )
theres this implementation in Javascript
https://jsxgraph.uni-bayreuth.de/wiki/index.php/Least-squares_circle_fitting
but to get the demo to render i had to wander around the site till i
found something that did render ,
then returm :-(
once it renders, refresh the page for a new random set of points
and a new fitted circle

ROTFLMAO! I missed that one at the time, shame on me.
Thanks Gregg.
