Autodesk Inventor subscription customers can download a special mid-year release that allows Inventor users to extend the functionality of Autodesk Inventor 11 products and better capture key Inventor information in DWF format. These DWF publishing enhancements are complementary with the latest release of Autodesk Design Review 2007 (formerly DWF Composer) and Autodesk DWF Viewer 7.0. The DWF Extension can be downloaded from the Autodesk Subscription Center. This extension performs a full uninstall of R11 and then performs a complete install. As such, some individual user settings are not preserved. This extension includes the corrections formerly released as R11 SP1.
