Background and Grid Page

The Background and Grid page of the Diagram Style window allows you to customize the appearance of the diagram. You can specify:

Whether to display grid lines and, if so, the style of the lines (e.g. solid, dash, etc.).
The size of the grid squares, in inches.
The size and color of the shadow “cast” by blocks in the diagram. Note that this applies to all block types, but the shadow will be shown only if the Show Shadow option is selected on the Defaults > General page for that block type.
The colors used for:
- The background.
- The grid lines.
- The page separator lines, which appear in the Print Layout view and indicate the boundaries of each printed page. You can display this view by choosing Home > Print > Print Layout.

The horizontal and vertical spacing, in inches, that will be used if you choose [Diagram/Fault Tree/Phase] > Blocks > Auto Arrange.

For fault trees, you can also choose the Always Auto Arrange option to turn on Auto Arrange by default.

Whether to display the block ID, which is an internal ID number assigned to each block when it is created. You can choose not to display the ID or to display it in decimal or hexadecimal format. If it is displayed, it will appear directly below the block name (i.e., its location, alignment and font will be dictated by the properties that are specified for the block caption).
