Design Web Format (DWF) is a file format developed by Autodesk for the efficient distribution and communication of rich design data to anyone who needs to view, review, or print design files. Because DWF files are highly compressed, they are smaller and faster to transmit than design files, without the overhead associated with complex CAD drawings (or the management of external links and dependencies). With DWF functionality, publishers of design data can limit the specific design data and plot styles to only what they want recipients to see and can publish multisheet drawing sets from multiple AutoCAD drawings in a single DWF file. They can also publish 3D models from most Autodesk design applications. DWF files are not a replacement for native CAD formats such as AutoCAD drawings (DWG). The sole purpose of DWF is to allow designers, engineers, project managers, and their colleagues to communicate design information and design content to anyone needing to view, review, or print design information – without these team members needing to know AutoCAD or other design software. An Autodesk DWF advocate blog cites as DWFs strengths over alternatives that the files have very high mathematical precision, and contain meta-data for sheets, objects and markup data. Another significant strength is that comments and markup can be reintroduced to, and edited in, some Autodesk products, such as Revit and AutoCAD. The AutoCAD file format (.dwfx) is based on ISO/IEC 29500-2:2008 Open Packaging Conventions. Technology DWF is a file format developed by Autodesk for representing design data in a manner that is independent of the original application software, hardware, and operating system used to create that design data. A DWF file can describe design data containing any combination of text, graphics, and images in a device independent and resolution independent format. These files can be one sheet or multiple sheets, very simple or extremely complex with a rich use of fonts, graphics, color, and images. The format also includes intelligent metadata that captures the design intent of the data being represented. The DWF technology centers on three components: C++ libraries for developers a viewer for project team members who wish to view design data without knowing AutoCAD a writer that allows anyone to create a DWF file from any application DWF Toolkit DWF is an open file format. Autodesk publishes the DWF specification and makes available C++ libraries (not available anymore) for any developer who wants
