Switches the view from a working sheet to the background sheet. When you set this toggle, all of the background sheets in the document are displayed as tabs at the bottom of window. All working sheet tabs are hidden. You can use a background sheet to draw graphics that you want to display on more than one drawing sheet. For example, you can draw borders and title blocks that contain your company logo, your name, and information about the drawings. This command is available only on the View menu.
You can display background sheet graphics on any or all working sheets, using Sheet Setup.
