A file format for that stands for “drawings,” which was developed by Mike Riddle in the 1970s and has become the most widely used format for CAD drawings due, in large part, to Autodesk using it as the basis for AutoCAD in 1982 and updating it numerous times since. Whenever a user inputs data in a CAD drawing, DWG houses all that data, which may include 2D and 3D designs, geometric information and photographs.
