Displays the action list for the current drawing session. You can use this list to undo multiple actions performed during the current drawing session.
Note:
Certain operations clear the undo list. For example, when you save a file or transition from one environment to another, the undo list is cleared. When the undo list is cleared, the Undo command is not available until more actions are added to the list.
The Undo command is not available when working with Alternate Assemblies. For more information, see the Alternate assemblies impact on Solid Edge functionality Help topic.
