Drawing Web Format, since DWF files were generated by the Autodesk Internet Publishing Kit. As the format grew in use beyond just AutoCAD, it was renamed to Design Web Format. Although originally a 2D-only format, DWF has evolved to include 3D. Today DWF files are generated by all Autodesk products. In addition, there are a variety of third-party applications that make use of the format. Alternatives PDF is an internationally recognized open file format developed by Adobe Systems to allow electronic exchange of any printable document, independent of the source application software, hardware and operating system. PDF/E is a subset of v1.6 of the PDF specification specifically designed for engineering use. SVG (Scalable Vector Graphics) is an open, XML based file format. It is suitable for use both as a format for creating and editing drawings and as a format for viewing and publication. For instance, Inkscape uses SVG as its native format, and both the Firefox and Opera browsers natively display SVG.
