SAVE TO CENTRAL PROJECT FILE

If you made changes in the project file you can save them back to the main central file.

But before doing so be confident you haven't messed anything up. There is no undo after saving.

Under Collaborate tab select the text part of Synchronize with Central, then Synchonize and Modify Settings.

Alternatively use the small icon in the quick access toolbar along the top. Just make sure it is showing the green arrows (if not use the command sequence described above).

A dialog box will appear. Make sure User-created Worksets is ticked (it is usually ticked by default, but check anyway).

Hit OK.

Done !
