PowerPoint guides can align an individual object or a group of objects to a vertical or horizontal guide. Turning on the visible grid or visible guides option makes it easier to create, modify, and align a shape. Within the Grid and Guides dialog box, you can select from a variety of options, such as snapping objects to the grid or to other objects and displaying drawing guides on-screen. To align several objects to a guide, you first turn the guides on. Then you adjust the guides and drag the objects to align them to the guide.
