Arranging objects in a circle

Every once in a while you'll need to draw a number of objects circling one big object. This is fairly simple, but you'll need to do some measuring to get the angles right. Fortunately, once you get the hang of this you'll be able to position anything around anything else without any trouble.

Here's what to do:
First things first: draw whatever it is you want to place the objects around.
Now that your object is there, lightly draw a line from its center. The longer your line, the farther out the other objects will be orbiting, since the end of this line marks the radius of the circle. Make a note of how long the line is so you can draw more like it in the next step.
Figure out how many objects will be orbiting the big one and then divide 360 by that number. This gives you the angle you'll be working with. For example, if you're going to draw twelve objects, then the angle will be 30°. The line drawn in the previous step was the 0° angle, so add your number and draw the next line at that angle.
Go all of the way around the figure, adding spokes as you go, until all of the lines are drawn.
The ends of the lines are where you need to add your new objects.
