Formato DWG is a file format commonly used in computer-aided design (CAD) software, with AutoCAD being a prominent example. The DWG file format was developed by Autodesk, the company behind AutoCAD, and it stands for Drawing.

One of the main advantages of formato DWG is its ability to store complex design and 2D or 3D data, making it highly useful for architects, engineers, and other professionals. It supports various types of entities, layers, and properties, allowing users to create and manipulate detailed drawings.

Being a closed proprietary format, DWG files can only be opened and edited using software that supports it, such as AutoCAD. However, Autodesk provides APIs and libraries for developers to integrate DWG compatibility into their applications.
