The DWG format is a special type of file that is designed to store two-dimensional and three-dimensional project data and metadata. This format was developed by Mike Riddle in the late 1970s for Interact CAD, and then Autodesk licensed it in 1982 and began to use it as the main format for storing its image files.
To date, the DWG format has two specifications. The first of them was developed by the non-profit consortium Open Design Alliance and can be found on the Internet. And the specification from Autodesk is available only to those developers who have been registered and approved by this company. It is known that with the advent of each subsequent version of AutoCAD, changes are made to the DWG file format. Before the 11th version of this program was released, the DWG format changed to a small extent. As a rule, the changes concerned only those moments that were associated with the new features of the new versions that appeared. In version 12 of AutoCAD, the DWG format almost remained unchanged, but this happened only because AutoCAD13 was created to work with a practically new DWG format.
