Link to External Project Files
One of the TimeLiner feature's most powerful features is its integration with project scheduling software. A list of tasks including their start and end dates/times can be imported from a project file directly into TimeLiner.
Note: When opening files that were created in Navisworks 2011 or earlier, you may find that the Planned and Actual dates have been swapped. Navisworks now uses Planned dates by default instead of Actual dates, as is consistent with most planning applications.
To switch date sets for affected files, edit the data source, switch the mapping of the Planned and Actual dates in the Field Selector Dialog Box, and then rebuild the task hierarchy (see To Build Tasks from a Data Source).
