Getting a Closer Look with Zoom and Pan

The example drawing in this chapter is pretty uncluttered and small, but most real CAD drawings are neither of those. Technical drawings are usually jam-packed with lines, text, and dimensions. CAD drawings often get plotted on sheets of paper that measure two to three feet on a side — that's in the hundreds of millimeters, if you're a metric maven. Anyone who owns a monitor that large probably can afford to hire a whole room of drafters (and therefore isn't reading this book). You need to zoom and pan in your drawings — a lot. I cover zooming and panning in detail in Chapter 12. Quick definitions should suffice for now:

  • Zoom means changing the magnification of the display. When you zoom in, you move closer to the drawing objects so you can see detail, and when you zoom out, you move farther away so you can see more of the drawing area.
  • Pan means moving from one area to another without changing the magnification. If you've used the scroll bars in any application, you've panned the display.

Zooming and panning frequently lets you see the details better, draw more confidently (because you can see what you're doing), and edit more quickly (because object selection is easier when a zillion objects aren't on the screen).

Fortunately, zooming and panning in AutoCAD is as simple as it is necessary. The following steps describe how to use AutoCAD's Zoom and Pan Realtime feature, which is pretty easy to operate and provides a lot of flexibility. ...
