 Zoom: Change the magnification of the display. When you zoom in, you move closer to the drawing objects so that you can see more detail; when you zoom out, you move farther away so that you can see more of the drawing area. Zooming does not change the size of the objects in the file. You can think of zoom in AutoCAD like the zoom function on your camera: You get closer, but you see less.

 Pan: Move from one area to another without changing the magnification. If you’ve used scroll bars in an application, you’ve panned the display. Panning does not change the location of objects in the file.

Frequently, zooming and panning let you see details better, and draw more confidently because you can see what you’re doing, and edit more quickly because object selection is easier when a bazillion objects aren’t on the screen.

Fortunately, zooming and panning in AutoCAD are as simple as they are necessary.
