Updating the Navisworks NWC Exporters

With (practically) each and every Service Pack/Update that Autodesk puts out for Navisworks, there is a corresponding update for the NWC Exporters…


How many of you actually download and install the update for the NWC Exporters?

Well, if you don’t, you should be.  I ran across an issue the other day where a customer was exporting a Revit 2014 model to NWC (2014) and many of the walls weren’t showing up when opening/appending the NWC file in Navisworks, even though the walls were visible in the Revit view. I got the file and tried it myself, worked perfectly. I knew the customer had SP1 for Navisworks 2014 installed, so I asked if they had also updated the Exporters…nope. Once they installed the update for the Exporters, all was good.

It’s very easy to miss, or should I say look over, when you go grab an update for Navisworks. But the next time Autodesk rolls out an update for Navisworks, make sure you also install the update for the Exporters (if it’s available).


  1. We found an issue with nwc files in Navisworks that the exporter updates so far have not fixed. When appending a dgn file directly into Navis, certain elements do not show up correctly. If we export the same dgn from MicroStation (NWCOUT), those same elements show up fine with the appended nwc in Navis.

    Are there different settings for exporting nwc files vs importing nwc files within Navis?

  2. Kurt, there aren't necessarily different settings, but the export will have it's settings and Navisworks will have the same settings. So some times it just making sure the settings match if you're getting different results.

    However, you might be running into an Object Enabler issue. After you open the DGN in Navisworks directly, go to Scene Statistics...this will show you if you are missing an Object Enabler.
