What is the difference between a DWG and DXF?

While DWG and DXF are both file formats for CAD software, DWG files are Autodesk’s proprietary format invented in 1982, and DXF is an open file format standard. Both file formats have similar functionality for storing 2D and 3D images, but DWG can store a wider array of files. Also, DWG’s binary code results in file sizes around 25% smaller than DXF files, which used text-based coding. Many designers use DWG when working, and then export to DXF to share their designs.
