Computer mice are very important when it comes to using AutoCAD, and you should understand by the present sentence that it will be practically impossible to use AutoCAD without making use of a computer mouse. It has become common to see CAD drafters handle soft work nowadays on a laptop, and chances are you are going to be operating your AutoCAD on a laptop as well at some point. What you need to know is, you need a mouse. You would simply not be able to use AutoCAD using the track-pad.
I will advice to find a 3 buttons mouse (left button, right button and scroll wheel) to start with. Later on you can find a more sophisticated mouse with perhaps programmable buttons.
AutoCAD and the computer mouse
Scroll up and down
Scroll up to zoom out and scroll down to zoom in.
You can also do this by using appropriate commands. Let’s see how much using this helps.
If we were to use the zoom in and zoom out not using the mouse, we will have to click on the navigation bar to select the command related to that action.
Press and hold the scroll wheel, then drag
Click and drag will help you panning. Acting as a shortcut for the Pan command.
To Pan in AutoCAD, Press and hold the scroll wheel, and drag. Some computer mice like the CadMouse (Recommended read: best CAD mouse) comes with a center button (Center click) that allow Panning without having to press the scroll wheel. The latter can be beneficial since it will require less effort to pan and there wont be any risk of Zooming in and out while panning.
There is no need to remind you that the right and left button play the same role as it would in other software.
