circularArcBlend

hello! hope u doing very well.

I need to approximate a semi-circle (or circular arc 45 deg) using cubic cp curve. any method for minimum deviation from true circular arc? thanks

arcblend command?

For a semi-circle, the arcBlend command creates a pair of tangential arcs (quadratic) joined. I need it to be a single cubic curve with minimum deviation. Any method?
