Positioning objects using guidelines

Guidelines consist of a snap property that automatically snaps objects to them. That is, objects connect to the guidelines as positioning devices.

Objects can snap to a horizontal guideline on the top, horizontal midline (the invisible line that bisects an object horizontally), or bottom.

Objects can snap to a vertical guideline on its left side, vertical midline (the invisible line that bisects an object vertically), or right side.

When a guideline has its snap property selected and the guideline is moved, all objects snapped to the guideline are moved. The snap property can be selected on the Layout tab in the Options dialog box. See Using the grid.

Note:    When a guideline is moved, any object that is snapped to it is moved as well. But if you move an object that is snapped to a guideline, the guideline does not move.
