I am receiving the above error message when using NavisWorks 2010 software. I believe I am trying to import NavisWorks 2012 .nwd files.
Is it possible to download a 2012 viewer to view 2012 files? I have been looking but can't seem to find one. Otherwise I guess the other solution is to have our MEP coordination team save the NavisWorks files in a 2010 file format (our company could also buy the 2012/2013 software, but this is the least cost effective alternative).
