DXF (Drawing eXchange Format) is a file format developed by Autodesk for 2D geometry interoperability between CAD systems. DXF get some limitations on blocks or unit and DWG file format is perfered when possible.
DWG (from DraWinG) is a binary file format for 2D and 3D geometry storage. The DWG format is probably the most widely used format for CAD drawings. Autodesk designs, defines, and iterates the DWG format as the native format for their CAD applications but many others CAD systems use DWG format as a native format (DraftSight, AutoCAD, IntelliCAD, ...) or as an interoperability format.
CAD Interop distributes several softwares to view, translate and validate DXF and DWG files. Find below the list of our solutions compatible with DXF and DWG formats:
