View History

The View Previous () and View Next () tools implement a history of your views.

The view history operates much like the forward and backward buttons in a web browser. Each zoom or pan action is added to the view history. The View Previous () button steps back through previous views and the View Next button () steps forward through the views. The buttons are disabled if there are no views in that direction. If you step back to a previous view and perform a zoom or pan action, the new view will replace the entire next view history.

The View History is implemented for plans and perspectives. Each plan or perspective’s view history is maintained separately. Switching from one plan or perspective to another does not affect the view history for either plan.

All zoom, extent, pan, and rotation view changes are recorded in the view history. Some consecutive view changes of the same type are compressed into one view history item to prevent the history from getting cluttered with many similar views. For example, consecutive Zoom In actions -- whether by the Zoom In tool or by mouse wheel movements -- add only one new view to the history.
