Click Enable Snapping to enable the snapping feature. Snapping assists in the precise placement of annotations, comments and other page content. There are three snapping options that can be combined as desired:

•Snap to Guides snaps content to the guides detailed here.
•Snap to Objects snaps content to document objects.
The Snap to Grid setting is active in the image below, and the Rectangle Tool is selected. This means that the rectangle corners must be located at grid intersections, and an icon displays at the current intersection during rectangle creation:
