The next first thing you should get familiar when first time learning AutoCAD is using navigation tools. You will want to see your drawing closer, move it to see another part of your drawing, see your model from different angle (for 3D), etc.
There are several methods to do it in AutoCAD:
This is probably the most common way in many applications. You can zoom in/zoom out your drawing by scrolling your scroll button. The drawing will be zoomed in/out about your pointer position.
You can pan by click the mid button, hold it, and move your mouse.
You can find the navigation tools in view tab, navigate panel. There are pan button, orbit (we will not discuss this until 3D tutorial), and zoom. There are several zoom tools you can use. The tool name should self explain what it’s for. But you might want to try them by yourself. Click the tool you want to use, then use it by hold your left mouse button. [Enter] to end the tool.
Using Steering Wheel
Steering wheel is the navigation tool that stick to your mouse. You can find the navigation tools here, like: zoom, pan, and rewind. If you want to try the navigation tools other than those three, try in 3D model. You can show/hide the steering wheel by pressing [shift]+W. Or click the steering wheel button on the try, right side of your status bar. (see animation below)
Typing in Command Line/Dynamic Input
This is probably the fastest way. You can type Z then [enter] to activate zoom tools. Press [enter] again will activate zoom real time. You have other zoom options if necessary. Refer to previous tutorial how to change the option.
Specify corner of window, enter a scale factor (nX or nXP), or
[All/Center/Dynamic/Extents/Previous/Scale/Window/Object] <real time>: W
Specify opposite corner:
Play this animation to see how it works. You can play it by right click and choose play from contextual menu.
Try to open sample files to do this exercise. You can find AutoCAD sample files in AutoCAD folder: C:\Program Files\AutoCAD 2010\Sample\Sheet Sets
