A practical solution to streaming large CAD models, NWD files require no model preparation, third-party server hosting, setup time, or ongoing costs. The Navisworks Freedom free download creates compressed, more secure, NWD format files. NWD files viewed with Navisworks Freedom give stakeholders equal access to explore and experience whole projects. Then, view these files with Navisworks® Freedom viewer software. Combine design data created in AutoCAD, Revit, and other applications with models created by other design tools. Get the whole-project view using Navisworks solutions.
