Like the AutoCAD Application window, you can minimize, maximize, reposition, resize, and check the state of any Document window. But you can also change the way the drawing is displayed within a window by using views, viewports, and zooming methods.
The AutoCAD .NET API provides many ways to display your drawing. You can control the drawing display to move quickly to different areas of your drawing while you track the overall effect of your changes. You can zoom to change magnification or pan to reposition the view in the graphics area, save a named view and then restore it when you need to plot or refer to specific details, or display several views at one time by splitting the screen into several tiled viewports.
