In 2006 Autodesk modified AutoCAD 2007, to include "TrustedDWG technology", a function which would embed a text string within DWG files written by the program: "Autodesk DWG.
This function was supported by an encrypted checksum and product code (called a "watermark" by Autodesk), written into DWG files created by the program.
In 1998, Autodesk added file verification to AutoCAD R14.01, through a function called DWGCHECK. (ODA has since rewritten and updated that code.)
The most successful is Open Design Alliance, a non-profit consortium created in 1998 by a number of software developers (including competitors to Autodesk), released a read/write/view library called the OpenDWG Toolkit, which was based on the MarComp AUTODIRECT libraries. Several companies have attempted to reverse engineer Autodesk's DWG format, and offer software libraries to read and write Autodesk DWG files. Autodesk sells a read/write library, called RealDWG, under selective licensing terms for use in non-competitive applications. As the biggest and most influential creator of DWG files it is Autodesk who designs, defines, and iterates the DWG format as the native format for their CAD applications.
There are several claims to control of the DWG format. Autodesk estimates that in 1998 there were in excess of two billion DWG files in existence. The DWG format is probably the most widely used format for CAD drawings. From 1982 to 2009, Autodesk created versions of AutoCAD which wrote no fewer than 18 major variants of the DWG file format, none of which is publicly documented. dwg filename extension) was the native file format for the Interact CAD package, developed by Mike Riddle in the late 1970s, and subsequently licensed by Autodesk in 1982 as the basis for AutoCAD.
