"Autodesk has been promoting its DWF format for nearly eight years. In the past, the company provided a free viewer for casual users who simply needed to look at 2D and 3D data, but required team members to purchase software if they wanted to be able to review and comment on designs. However, now with the release of the latest version of its Design Review 2008 software, Autodesk has made the program free, so that all stakeholders have access to fully functional software to view, measure, mark up, annotate, print, and round-trip designs.
All of Autodesk's products can publish CAD data as DWF files and marked-up DWF files can be saved from Design Review and sent back to the original CAD application (an AutoCAD-based product, Inventor, or Revit) where they can be opened and viewed in the context of the original CAD file.
The company also makes available a free DWF Writer application to create DWF files from any other Windows application with special plug-ins that provide enhanced capabilities when publishing DWF files from SolidWorks, Pro/ Engineer, and CATIA. There are also plug-ins for Design Review that offer import and publish capabilities for UGS' JT format and MicroStation DGN files."
