Turning on the Show Extras? option in the View pull-down menu will reveal a grid of points, representing the current grid settings. (Show Extras? also shows any guides if set).
The default is a 10 x 10 pixel grid with the origin point at position 0,0, that is, the top left corner of the page. Turning on the grid will not cause elements to move or change size.
You can adjust the size and origin of the grid in the Grid Editor panel. Click Edit Grid from the Tools pull-down menu to open the Grid Editor panel. The Show Grid? option is automatically turned on. Within this dialog, you can adjust the grid, either graphically or numerically.
Re-sizing the Grid
The smaller the grid size values, the more freedom you have to position and resize elements. Both the width and height contain a range from a minimum of 4 to any desired maximum size.
To graphically edit the size of the grid, drag the solid graphic handle, which is located below and to the right of the origin (initially the upper left corner of the page). To numerically edit the size of the grid, simply highlight the value in the Grid Size control which you want to change, (width or height), and use the value control to increase or decrease the number.
As the values are edited, you will see the grid change. With coarser settings, the grid lines become farther apart and the “boxes” in the grid will become larger.
Here is a pair of images, with the grid at its default, and expanded in size in the second photo.
Moving the Grid on the Page
You can re-position the entire grid relative to the page, so that even with coarse grid settings you will still have considerable freedom in positioning items. The grid origin is represented by a hollow graphic handle crossed by two solid lines. By default, it is set to 0,0, which is located in the upper left corner of the page. You can drag this handle, or you can adjust the values in the Grid Origin control. Any pixel position (regardless of the grid size) can also be set as the origin.
When you are finished in the Grid Settings dialog, click Done. The grid settings apply to every page in every open script, however, they will only have an effect while you are editing a page. They can be retained for future use by clicking Save Element and Page Defaults from the Tools pull-down menu, and are not saved with scripts.
Using the Grid
The grid can be used purely as a visual aid or can assist alignment if the Snap? option is set you can easily position elements to consistently line up on the page.
When turned on, this option will allow elements to be specifically positioned at grid points. When you drag with the grid on, the horizontal and vertical leading edges of the elements will show a visible yellow line where they can “snap” into the possible positions defined by the horizontal and vertical grid size values. However, if you quit dragging in-between two grid points, the element will not automatically jump to the snap position.
