Hip tip: Zoom and Pan via mouse scroll

I am going to touch on two system variables in this article that will be useful for you. These are MBUTTONPAN and ZOOMFACTOR.

MBUTTONPAN: Autocad users mostly use the mouse scroll to pan or zoom. It zooms in when you spin the scroll towards you and zooms out when you spin it towards the monitor. Holding it pushed also enables the pan command. Yet, some computers have some trouble about these properties because of a small setting of Autocad. If your computer does not do the things mentioned above, set the system variable MBUTTONPAN to 1 by typing the command (mbuttonpan) into the command line. If it is “0” , Object Snap Menu will appear when you push the scroll.



ZOOMFACTOR: It is very practical using mouse scroll to zoom in or out. But sometimes it is very tiring as scrolling again and again to zoom in and out in detailed drawings. On the other hand, one scroll can be too much for simple drawings. To cope with this problem, you have to change the ZOOMFACTOR system variable. It is sufficient to type ‘zoomfactor’ into the command line and set a value between 3 and 100 which designates the zoom intervals.
