The command to change the properties of an object in AutoCAD is PROPERTIES. This command brings up the Properties palette, which allows users to view and edit various attributes of selected objects, such as layer, color, linetype, and other settings specific to the object's type.

Using the PROPERTIES command is especially useful because it provides a clear and organized way to access all relevant properties in one place. When you select an object and invoke the PROPERTIES command, you can see detailed information and make changes in real time, which enhances workflow efficiency.

In contrast, while other commands like EDIT, CHANGE, and MODIFY may imply some changes to objects, they do not specifically target the comprehensive property adjustments that the PROPERTIES command does. EDIT, for instance, isn't a standard AutoCAD command by itself for changing object properties. CHANGE generally refers to altering the geometry or characteristics of objects but lacks the detailed property interface that PROPERTIES provides. MODIFY can encompass a broader range of editing capabilities, but it does not specifically focus on properties the way the PROPERTIES command does. Thus, PROPERTIES is the most direct and effective choice for altering object attributes in AutoCAD.
