AI Drawing Prompt Reference

Draw a hexagon, then rotate each vertex 60 degrees to form the exterior angles. Next, draw arcs for each exterior angle using circular arcs and circles. Finally, find points on the circumscribed circle of the hexagon through intersections to form the circumscribed circle.
