File type: Drawing Exchange Format
The DXF file extension is used in Autodesk applications for Drawing Interchange Format or Drawing Exchange Format files. This data file format for CAD files was created by Autodesk for the purpose of allowing data interoperability among Autodesk software and other applications.
It was initially launched as a component of the AutoCAD 1.0 in December 1982. The release had the intention to provide the same and exact data representation of an AutoCAD drawing with the .dwg file extension, which is its local file format.
The files with the .dxf file extension are vector image files and are the data format designed by Autodesk used in computer-aided design.
It is similar to the DWG but it has more compatibility with other programs because it is cased in ASCII. AutoCAD versions from Version 10 and later support binary and ASCII forms of files with the .dxf file extension. Early versions of AutoCAD only support ASCII.
