We recently downloaded Navisworks Freedom 2011 at our office so we could give it a try and see how it works. I've been trying to create an NWD file from Revit 2011 but have only been able to create NWC files. I used the official Exporter Tool that I downloaded from Autodesk, and there doesn't appear to be an option to export a Revit file in NWD. Is there any way to create an NWD file from Revit, or is this a trick to get us to pony up for Navisworks Simulate/Manage?
