Not sure I entirely understand what you are trying to do with all the circles, but you can smooth out the appearance by changing the "viewres" variable. Just type in "viewres" and follow the prompts. It has a maximum setting of 20000, but unless your drawing is very small, you'll see performance degrade considerably with that setting on a larger file size. Start at 2000 and see if that takes care of it. You can change it up or down at anytime.
