DWF
– Design Web FormatDWF stands for Design Web Format and is a file format developed by Autodesk for efficient sharing and distribution of CAD design data. DWF files are highly compressed, making them smaller and faster to transmit than traditional CAD files. They can contain 2D drawings, 3D models, text, and metadata, and can be viewed using free tools like Autodesk Design Review without requiring specialized CAD software.
