Anyway, it failed miserably and could not solve.. Not sure why it failed. But my opinion is it doesnt matter, because what sent me down this rabbit hole was inability to do a simple mirror inside sketch with any line as the delineator which should be a feature since the rabbit hole is prone to collapsing with its overly complex workflow. A better mirror will solve this issue much more simply than delving into mechanics of solving sketches.
How annoying -- It takes 1 second to extract the part of the sketch to flip around. But from here there's no way to flip it around. I could spend 3 hours and not succeed I think. Please! fix :'(
So now I will finish my sketch and hope my eye is a good enough ruler to make these arcs close enough to symmetric
