Model overview pane
Modeling area pane. Displays the model in an overview. You can quickly change the visible area of the model window by moving the frame displayed. The size of the frame is determined by the size of appearance that you set in the Size of appearance box in the toolbar. The lower the percentage you enter in the Size of appearance box, the larger the visible area and thus the frame of the model overview, and vice versa.
You can specify that the pane is only visible when required.
