What is a DWG file? Native to AutoCAD, Autodeskโs computer-aided design (CAD) suite, DWG is both a file format and a CAD operating environment. DWG files are among the most popular and widely utilized CAD file formats among engineers and designers in almost every industry.
Let's dive deeper into:

A DWG file is a proprietary (closed-source) file format used for storing two-dimensional (2D) and three-dimensional (3D) drawings, model data, and metadata.
The DWG file extension is a binary file format that stores data in a highly compressed form. This makes it ideal for storing large design files but can also make it difficult to open DWG files if you don't have the right software.
The file ext .dwg is the file extension used by DWG files.
Donโt confuse DWG files with DXF files. In 1982, Autodesk also released the neutral (open-source) DXF file format to store 2D and 3D design data.
Though both file types are used in CAD/CAM applications, they are not the same. Unlike DWG, DXF stores data as plain text, which makes file sizes large.
Only Autodesk and licensed software can read and write DWG file formats. Some software and DWG viewers that can open the .dwg file extension are:
DWG file extension is not a widely supported file format, meaning users can encounter errors trying to open files. Some common issues users report trying to use or view .dwg files are:
Since DWG files are a proprietary file type, non-Autodesk CAD applications cannot open the file natively. In order to import a file with the DWG extension, it must first be converted by the application. This can cause issues such as:
