You don't need Navisworks to create Navisworks NWC files from your AutoCAD or Revit models.

The distributable NWC file exporter program enables project teams using Autodesk Naviswork software to generate whole-project models for simulation and analysis. Project team members can generate the optimized NWC file directly from their design applications. This capability is provided without necessitating a licensed seat of Autodesk Navisworks 2010 software on the same machine. The NWC exporter works with a range of products, including the AutoCAD-based and Revit-based Autodesk products, as well as Autodesk 3ds Max, Bentley MicroStation, and Graphisoft ArchiCAD software. The NWC file format supports transfer of both object geometry and associated metadata from the design applications into Autodesk Navisworks 2010 software.

Using NWC File Exporter Pack

The NWC file exporter pack enables project team members generate the optimized NWC files directly from their design applications.

The NWC file enables transfer of both object geometry and associated metadata (such as object properties and materials) from the design applications into Autodesk Navisworks 2010.

The NWC exporter pack works with a range of products including AutoCAD-based applications, Revit-based applications, 3DS MAX and Viz, Microstation, and ArchiCAD.

You can distribute link to a download page for the NWC exporter pack to any project team member.
