There are several methods or Appending a Revit model into Navisworks. The method that is most efficient is debatable and often a compromise between performance and manual effort, unless you have IMAGINiT Clarity which can export .nwc (Navisworks Cache) automatically by schedule or on demand.
Navisworks has the ability to link in a Revit model directly by “appending” the .rvt file. The advantage to this method is that as you resolve clashes or make changes you can save the Revit file and click Refresh in Navisworks. It also eliminates much of the manual effort of exporting NWC files repeatedly.
If you have tried this method you have likely had the problem when linking Revit into Navisworks, Revit elements are missing. To solve or avoid this problem you need to understand and check the settings in Navisworks.
4. To resolve the problem of missing Revit Elements, check the Convert settings. There are three options; Navisworks View, First 3D View, and Entire Project.
a. By using Navisworks View the program will only import views that contain the word “Navis” in the name and it will only import Elements contained in those views.
b. Entire Project will bring in all of the Elements and 3D Views in the Revit Project you wish to Append.
Leveraging the Navisworks View by setting up named views in the Revit model or changing the setting to Entire Project should resolve the problem of Missing Elements when Appending/Linking Revit into Navisworks.
