How to Disable Mouse Wheel in AutoCAD?

Disabling the Mouse Wheel in AutoCAD

The mouse wheel can be a useful tool in AutoCAD for zooming and panning, but there may be instances where you want to disable it. The following steps provide a comprehensive guide to help you turn off the mouse wheel functionality within AutoCAD 2025.

Step 1: Adjust AutoCAD Settings

Accessing the Preferences

3. Select “Options” from the dropdown.

Changing Mouse Settings

1. In the Options dialog, go to the "User Preferences" tab.

Step 2: Alter the Zoom Factor

Modifying Zoom Settings

1. Type ZOOMFACTOR in the command line and press Enter.
