Guides are non-printing, non-exporting lines that float over page objects and assist with their positioning. There are two types of guides to aid a variety of designs—ruler and column. They can be created and positioned by dragging from a ruler (for 'by eye' placement) or via the Guides Manager (for precision using the document's units or a percentage).
Ruler guides
Ruler guides can be set in accordance with the horizontal or vertical ruler, but can be freely moved and positioned on your page.
To add a ruler guide:
Do one of the following:
With the Move Tool active, drag from either the horizontal or vertical ruler which can be switched on via the View menu.
From the View menu, select Guides Manager. Click the Add new guide icon for either horizontal or vertical ruler guides.
To move a placed ruler guide:
Do one of the following:
Drag the guide with the Move Tool when you see the cursor change.
With any tool, ensure that Show Rulers is switched on (via the View menu) and drag the guide marker directly from the horizontal or vertical ruler to reposition the guide.
From the View menu, select Guides Manager. Double-click on the value for the guide you want to edit and type a new position into the value field. (Note that you do not need to type the units.)
To position ruler guides by percentage:
From the View menu, select Guides Manager.
Select the Percent option.
Percentages are calculated from the top-left of the document page.
To show or hide ruler guides:
From the View menu, select Show Guides. A check mark is displayed next to the menu item when the guides are visible.
To remove ruler guides:
Do one of the following:
With the Move Tool selected, drag the guide off the page.
From the View menu, select Guides Manager. Click to select the value for the guide you want to delete and then click the Remove guide icon.
To lock all guides:
From the View menu, select Lock Guides.
Column guides
Column guides allow you to specify a number of evenly spaced columns and rows and are perfect for designing layouts such as web mockups.
To add a column guide:
From the View menu, switch on Show Column Guides then select Guides Manager. The Column Guides section allows you to manage the following:
Columns—defines the number of vertical guides that will appear.
Rows—defines the number of horizontal guides that will appear.
Gutter—defines the size of the gutter.
Style—select from Filled or Outline.
Colour—click the colour swatch to select a colour for your column guides.
To show or hide column guides:
From the View menu, select Show Column Guides. A check mark is displayed next to the menu item when the guides are visible.
To remove column guides:
From the View menu, select Guides Manager. Reduce the number of Columns and Rows in the Column Guides section to 1.
