The Ruler Tool in Illustrator (how to delete or move the guides)

Create guides

1. If the rulers aren’t showing, choose View > Show Rulers.
2. Position the pointer on the left ruler for a vertical guide or on the top ruler for a horizontal guide.
3. Drag the guide into position.
   You can also convert vector objects to guides by selecting them and choosing View > Guides > Make Guides.
   To make working with multiple guides easier, move them into a separate layer.
4. If you want to restrict the guides to an artboard and not to the entire canvas, then select the Artboard tool and then drag the guides on to the artboard.

Move, delete, or release guides

1. If guides are locked, select View > Guides > Lock Guides.
2. Do any of the following:
   • Move the guide by dragging or copying.
   • Delete the guide by pressing Backspace (Windows) or Delete (Mac OS), or by choosing Edit > Cut or Edit > Clear.
   • Delete all guides at once by choosing View > Guides > Clear Guides.
   • Release the guide, turning it back into a regular graphic object, by selecting the guide and choosing View > Guides > Release Guides.

Snap objects to anchor points and guides

1. Choose View > Snap To Point.
2. Select the object you want to move, and position the pointer on the exact point you want to align with anchor points and guides.
   Important: When snapping to a point, the snapping alignment depends on the position of the pointer, not the edges of the dragged object.
3. Drag the object to the desired location.
   When the pointer comes within 2 pixels of an anchor point or guide, it snaps to the point. The pointer changes from a filled arrowhead to a hollow arrowhead when a snap occurs.
