What Is a DWG File and How Do I Open It?
DWG file is a widely used CAD file format developed by Autodesk for storing 2D and 3D design data. The name “DWG” stands for “drawing”, and it is the native format for AutoCAD, one of the most popular CAD software in the world.
Although originally created for AutoCAD, this format has become widely supported by many other CAD software due to its popularity and broad adoption. Today, it is considered a universal file format in the design and engineering world, enabling smoother collaboration and interoperability across different software platforms.
To open DWG files, there are typically three methods:
- CAD Software: If you wish to open and edit DWG files, CAD software is the preferred method. Applications like AutoCAD, ZWCAD, Autodesk Fusion 360, or other compatible software offer the necessary tools for viewing, editing, and working with DWG files.
- CAD Viewers: These are specialized tools designed for viewing DWG files without editing capabilities. They are lightweight and often free, making them ideal for quick previews or sharing drawings with clients and colleagues who don’t need to make changes.
- Open DWD files Online: Online DWG viewers allow you to open and view DWG files directly in your web browser. This option offers convenience and accessibility, especially for occasional users or those on mobile devices.
While these three methods are universal, the exact tools can vary depending on your operating system. Next, we’ll take a closer look at how to open DWG files on Windows, macOS, Linux, Android, and iOS.
