Inside the Autodesk App Store, download and run the OneNote add-in. It will show up in the OneNote tab on your ribbon within Navisworks.

In order to start taking notes for a particular drawing, click on the OneNote App, and it will bring up a window for that drawing. If you are not logged in to your Microsoft account, it will ask you to login. Once you have entered your Microsoft account credentials, the app will ask you for permission to access your OneDrive where these notes will be stored. Once you accept, it will create a OneNote page for your drawing, and you can start typing your notes! As you type these notes, they get automatically saved to the cloud. 

If you open another drawing, it will create another page for that drawing where you can type notes for this drawing. As you switch between drawings, the app will open the page for the current drawing, so that your notes are organized. 

The next time you open a drawing within Navisworks, the OneNote app will open up the notes you had taken for that drawing!
