Aerial View Window -- ZWCAD 2009 new feature
Traditionally, we roll or hold the mouse wheel button to zoom or pan a drawing, or even have to use the command line, toolbar, or menu. Are you feeling tired of frequently rolling and pressing the little wheel? Is repeated operation with the command line, toolbar, or menu bothering you? If so, then try the Aerial View Window.
It is a special and helpful tool for quick navigation in a drawing of large scale. Instead of using traditional methods, zooming and panning in the drawing area can be achieved simply by resizing and moving a small rectangle in the Aerial View Window.
