To Add Guide Lines
Layout is a key aspect to good design. Guides are used extensively during layout to keep objects properly aligned. Guides are placed on a Guide layer.
With the Rulers visible (View > Show Rulers & Format Bar from the main menu), drag from a ruler onto your drawing canvas. A guide will be placed. Multiple guides can be placed, and the layer can be made visible or hidden from the layers list. Guides are not printed.
To Move Guides Around
With the Guide layer active, click onto a guide and drag it into desired position. Constrain guides to the Graph Paper divisions by holding the SHIFT key while moving a guide. To keep objects and text aligned to the guides, choose Graphic > Snap To Guides from the main menu. When you are finished, click back onto a drawing layer to make it active and continue drawing.
To Delete Guides
Drag a guide off the canvas area onto a ruler to delete it.
