Guides help you align text and graphic objects. You can create ruler guides (straight vertical or horizontal lines) and guide objects (vector objects that you convert to guides). Like the grid, guides do not print.
You can choose between two guide styles—dots and lines—and you can change the color of guides by using either predefined guide colors or colors you select using a color picker. By default, guides are unlocked so that you can move, modify, delete, or revert them, but you can choose to lock them into place.
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.
