If I draw a circle, and I zoom in on it a bit, I can see that it's actually comprised of straight edges. So the default number of edges in a circle is 24, but I have some control over that. So, if I want to draw a circle that looks smoother, I can hit C for circle, and I can see down here in the Measurements box that it's going to have 24 sides. I can make that a higher number, say 64, Enter, and now, when I draw a circle, it's going to have 64 sides and look quite a bit smoother than the circle to the left with 24 sides.

So I'm going to draw the circle, click and release to drop it, and I'm going to type 132, S for sides, Enter. Now, it's…
