oddly, if I copy and paste the big arc and try to type in new starting and stopping angles, it doesn't change the arc at all. Still the same as the orgiginal.
THis is problematic, because I am no longer able to draw the same exact arc. I need to be able to manually type in and tweak the arc center, starting angle and end angle. It is like a bug, that it doesn't change when I fluff the numbers.
