Whilst on support recently, a frustrated new Navisworks user asked about updating models. He complained that when they have Navisworks open, they couldn't update their Revit NWC files. If you need to continually append models to Navisworks and you don't want to shut down Navisworks, the following is the best solution is for you.
Under Options Editor, Model, Performance, make sure that the "Close NWC/NWD files on load" is ticked.
This will allow you to overwrite the NWC file while that file is open in Navisworks.
