View the version history of drawings stored in the cloud in the new Drawing History palette, where you can compare them with the current version of your drawing.
If you save drawing files to a OneDrive, Dropbox, or Box account, additional versions of these drawing files are created as you work, creating a version history. The previous versions will be listed in the new Drawing History palette so you can compare them with the current version of your drawing.

The Compare control opens the Drawing Compare feature to identify geometric or text differences between the versions. See About Comparing Differences Between Drawings for more information.
