Export to Web App / Synchronize with Web App

If this is the first export of the current Revit to Web App, this command will be called Export to App.

Otherwise, it will be called Synchronize with Web App.

In any case, clicking it will start the export/synchronization process with the settings previously configured in the Manage Scope dialog. Clicking the Export/Synchronize button in the Manage Scope dialog will basically do the same thing.
