When appending multiple native files into Navisworks, sometimes things may not look as expected or start to “ghost” or “glitch” when navigating:
The solution is to use the Navisworks NWC Export Utility that can found at the bottom of the link below:
Navisworks 3D Viewer | Download Free Navisworks Freedom | Autodesk
This exports a NWC file directly from the native software, so that it can be used in Navisworks afterwards. This seems to generate a more stable file, so is helpful when encountering issues like this.
