What type of motion does the OFFSET command primarily affect?

The OFFSET command primarily affects linear motion by specifying a movement that displaces the grip position or tool path along a straight line relative to the defined coordinates. Its primary function is to adjust the position of an element (such as a tool or end effector) in a way that often impacts the linear path it will take when executing a task.

While the OFFSET command can indirectly influence circular and rotational motion by changing the starting point of a movement or altering the path of rotation, its primary application is in managing linear adjustments. This is why the emphasis on linear motion is appropriate in the context of the question.
