Overview Pane
The Overview Pane allows you to determine the part of the model on which the primary pane should focus. It provides a complete view of the model with a shaded rectangular area representing the current view port, which represents a subset of the model. Click your cursor near the area of the model where you want to focus and see the model move in the primary pane. Click the center of your model to have the focus on the entire model.
Note: This pane is on by default but can be toggled off and on using the Overview button on the
Tools ribbon of the View tab.
