Which of the following is NOT a method to adjust the Snap settings?

The correct answer highlights that changing the operator settings is not a method for adjusting the Snap settings in AutoCAD. Snap settings specifically relate to how objects are snapped or aligned while drawing and drafting, and are defined through dedicated commands and settings within the software.

Using the SNAP command allows users to enable, disable, or modify the snap behavior directly through the command line or command interface. Accessing the Drafting Settings dialog is another vital method where users can manage various drafting aids, including Snap settings, to enhance their design precision. Additionally, the status bar options provide quick access to toggle or adjust Snap settings for convenient adjustments while working on drawings.

In contrast, changing operator settings typically involves modifying preferences related to user input or system operation rather than specifically altering the snapping mechanics, which is why it is not considered a valid method for adjusting the Snap settings in AutoCAD.
