I'd like to be able to do this as well. 
 
Navisworks' web site <
http://www.navisworks.com/support/file_formats/ch01s08.html> says it's possible "ArchiCAD can export to NavisWorks .nwc file format. JetStream does NOT have a direct reader for ArchiCAD files", but I can't find anything on Graphisoft's web site. 
 
However it does look like .ifc files may now work - so perhaps this is another option?
