G code has two commands for arcs, clockwise and counterclockwise.
It's very "go to the next point from where you are now" in it's outlook.
Arcs have an end x, y, z point and you either get a radius or an offset to the centre.
If you only get the radius there are two possible solutions so radius arcs over 180 degrees have to be broken into two but your software should be doing all this for you.
AFAIK AutoCad trims circles to arcs. OTOH I've never managed to figure out the rules for trimming rectangles, sometimes bits stick and get included in the original polyline
