What is a common use of the "OFFSET" command in AutoCAD?

The "OFFSET" command in AutoCAD is primarily used to create parallel copies of an object at a specified distance. This function allows users to easily produce duplicate geometries without the need to manually redraw them, maintaining the original shape while specifying the distance for the new copy. For instance, when designing elements such as roadways, walls, or other parallel structures, the OFFSET command expedites the process by enabling the user to create multiple copies at consistent intervals. This feature is especially useful in drafting and design, where precision and efficiency are crucial.

The other options highlight different functionalities within AutoCAD that do not pertain to the action of creating parallel copies. Some focus on scaling, line management, or alignment, which are significant operations but distinct from the core purpose of the OFFSET command.
