Alignment guides are horizontal and vertical rulers that you can add to a panel. You can position them anywhere in your stage, and use them to help you align layers and artwork as well as to draw along their axis.
Alignment guides can be used as visual aids, but you can also make your animation and drawing tools snap to them.
The following tools can snap to alignment guides:
|Layer Transform||Select||Contour Editor|
Tools such as the Layer Transform tool and the Select tool, which allow you to select and manipulate objects, will snap your selection to nearby alignment guides as you manipulate it. As for the Brush or the Pencil tool, your drawing tool will snap to a nearby alignment guide if you draw close enough to it, allowing you to draw a straight line along the guide, as if you were drawing with a ruler.
