Tip and Trick Detail
Increasing the Zoom factor used with Scroll Wheel on Intellimouse
*Applies to: AutoCAD 2000, 2000i, 2002, 2004 and 2005*

AutoCAD 2000 introduced support for the Intellimouse. The Intellimouse added support for a scrolling wheel in the middle of the mouse. This wheel can be used for a wide variety of tasks. The common use for this wheel is to easily scroll in a document or in the case of AutoCAD is to Zoom in and out in a drawing. Since everyone works differently and on different types of drawings we all need to zoom at a different rate. So Autodesk added a system variable called ZOOMFACTOR to allow a user to change the zoom factor/rate. The higher the number, the more incremental the change that is generated by each roll of the mouse-wheel when moved forward or backwards. The valid range for this system variable is 3 - 100.

Command Line:
Command: zoomfactor
Enter new value for ZOOMFACTOR <40>: 25
