Now that we know AutoCAD files, it’s time to open them for free. So, DWG is the most common AutoCAD file since it’s smaller than DXF, while still compatible with all of the design tools. To give you a metaphor, DWF is to DWG what PDF is to Microsoft Word. However, you can’t edit DWF files in AutoCAD. Meanwhile, DWF files are the most compact and suitable for sharing through the web.

DWG is better optimized, and is the most used drawing file format in AutoCAD.

Many other CAD software are also able to import or export DWG and DXF files, due to AutoCAD’s widespread use and recognition in the industry.ĭWG file format stores the design data in binary code (0s and 1s), while DXF stores the data in ASCII code (character strings). These file formats are trademarked by AutoCAD and are widely used in the CAD industry. What Are AutoCAD File Formats?ĪutoCAD is capable of importing and exporting various file types from other programs, but also has three proprietary file formats that are specific to AutoCAD: DWG, DXF, and DWF.
