Design guides are horizontal and vertical lines that you place in your report to help you line up objects. Design guides are similar to grids in that objects automatically snap to align to the design guides.
If rulers are visible, click the ruler and drag one or more design guides from both the horizontal and vertical rulers.
To toggle the display of design guides, select A check mark is displayed next to Design Guides to indicate they are visible. Select the option again to clear the check mark and remove the design guides.
