DWG files are popular with builders, architects, designers and anyone who needs to create 3D rendered images.
The DWG format was first developed in the 1970s by AutoDesk, the makers of AutoCAD, and is a format know for interoperability with other CAD software such as CATIA and Solidworks.
The file itself is made up of vector data coupled with metadata and either 2D or 3D CAD drawings. It's called DWG because it's a shortened version of the word "Drawing" which is what a DWG file essentially is. A DWG file is a CAD (Computer Aided Design) file that has been created with a program called AutoCAD, one of the most popular CAD programs on the market.
