You can minimize, maximize, reposition, resize, and check the state of any Document window.
The way a drawing is displayed within a window by using views, viewports, and zooming methods can also be manipulated with the Document object.
AutoCAD ActiveX provides many ways to display views of 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 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.
