The Revert to Saved command replaces the active drawing with the most recently saved version. This deletes all changes made since the last save, which can remove several undesirable changes in one step.
To revert to the last saved version:
Select File > Revert to Saved.
This action cannot be undone. Confirm that changes should not be saved.
Click OK.
The program closes the active drawing and opens the last saved version of the file.
