Tip
You can also choose View > Rulers > Show Rulers.
- Click each of the artboards, and as you do, look at the horizontal and vertical rulers (along the
top and left sides of the Document window).
Notice that 0 (zero) for each ruler is in the upper-left corner of the active (selected) artboard
(the last artboard you clicked in). The point on each ruler (horizontal and vertical) where the 0
appears is called the ruler origin. By default, the ruler origin is in the upper-left corner of the
active (selected) artboard. As you can see, the 0 point on both rulers corresponds to the edges
of the active artboard.
