Autodesk DWF Toolkit 6
The DWF™ 6.0 Toolkit allows you to develop applications that read or write multi-sheet drawings in DWF™ (Design Web Format™) format. The toolkit contains a C++ library that aids in the generation, reading, and parsing of DWF files. You can use it to work with DWF files without having to understand their complete underlying data format. This toolkit contains support for the DWF file as defined with the release of AutoCAD 2004.
