This script will approximate an ellipse with 4 or 8 circular arcs all symmetrical about the ellipse’s major and minor axes and with all G1 joints.
- The 4-arc method finds the pair of arcs with minimal maximum deviation from the ellipse.
- The 8-arc method first creates arcs through the axes with the same curvature as the ellipse at the axes intersections, then finds the fillet between the two that results in minimizing the maximum deviation between the 3 arcs and the ellipse.
