Autodesk® Navisworks® Freedom software is the free* viewer for NWD files created by Autodesk® Navisworks® 3D project review software products.† Combine design data that was created in building information modeling (BIM) applications—such as the Revit® family of products—with geometry and information created using other design tools. Then publish the entire model to NWD format, including properties, comments, viewpoints, and 4D playback. Navisworks Freedom and the compact and streamable NWD file format give project stakeholders better access to whole-project views. Improve quality by enabling widespread real-time experience of entire design projects before they are real.
