View menu - Set Grid
You use the Set Grid command to configure the gridlines that are displayed in regular intervals across the page. You see the Set Grid dialog, in which you can specify the horizontal and vertical spacing that appears between each gridline. Large values result in a course grid, which is useful if you want to size and position items approximately; small values result in a fine grid, which is useful for more detailed work. You can enter values between 1 and 210.
