We need a better way to draw arcs or poly arcs, like in cad or illustrator.
I agree. The 3 point arc in cad similarly there's a takeoff software I used called Planswift that had a nice way of drawing arc's when doing a takeoff. Measuring out curb with arcs becomes 3 clicks for every arc. You click the starting point, the center of the arc and the end of the arc to close it.
