Dave 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 a million truck mud flaps ( before the mermaid ) iirc it was fairly manual, he'd pick out a series of lines that approximated an arc and his tool would grab the begin/end point of the list of lines, then a bit of APT logic with a 'which side' click ( on the plotter, no mouse yet ) resulting in an arc that was tangent at begin and end ( or an arc and an additional tangent exit )
