Pan and Zoom with the Aerial View Window
In a large drawing, you can pan and zoom quickly in a window that can display
the whole drawing.
You can use the Aerial View window to change the view in your current
viewport quickly. If you keep the Aerial View window open as you work, you
can zoom and pan without interrupting your current command. You can also
specify a new view without having to choose a menu option or enter a
command.
Use the View Box to Pan and Zoom
Within the Aerial View window is a view box, a heavy rectangle that displays
the boundary of the view in your current viewport. You can change the view
in the drawing by changing the view box in the Aerial View window. To zoom
in to the drawing, make the view box smaller. To zoom out of the drawing,
make the view box larger. All pan and zoom operations are performed by
left-clicking. Right-click to end a pan or zoom operation.
