If you try to export a view from Revit 2013 to Navisworks and it contains a linked point cloud file, the point file will not be converted even if the "Convert linked files" option is ticked in Navisworks settings.
Here are some workarounds:
Some have recommended importing the PCG into AutoCAD, and export an NWC from there:

You can also:
- Import PCG to AutoCAD, then append the DWG to Navisworks
- get PTS from Cyclone, or even TXT, and then append it directly to Navisworks
Point Cloud files imported into Navisworks & Revit from Cyclone, .pts vs .ptx. | LinkedIn
Depending on the size of the original point cloud file, it will take some time for Navis to make the necessary indexed NWC file (like half a day maybe).
Obviously, if you are living in 2014-Suite-Land, you can also just use Recap to import the PCG and export as a supported file format for Navisworks.
