    "abstract": "DWG is the proprietary native file format for AutoCAD, one of the most popular computer-assisted design (CAD) packages. The format is maintained by Autodesk. DWG is a compact binary format that stores and describes the content of 2D and 3D design data and metadata. AutoCAD 1.0 was released in 1982, but the origins of the DWG format are from the late 1970s, when it was the native format for a CAD package called Interact. The format has been updated frequently as the AutoCAD product has been enhanced.",
