## Function Description:
This command is used to create concentric circles, parallel lines and parallel curves. Users can offset a selected object by a specified distance or a point. After offsetting objects, users can use the TRIM or EXTEND command to create drawings with several parallel lines and curves.
For the convenience of use, the OFFSET command will not stop prompting until you press Enter to exit.
