DXF File Format

  • DXF is short for Drawing Interchange Format or Drawing Exchange Format. Commonly known as AutoCAD DXF format, is a CAD data file format. 
  • It was developed by Autodesk to enable data interoperability between AutoCAD and other programs. DXF file format was first introduced in 1982. 
  • The key purpose of this format was to produce the exact representation of AutoCAD native DWG files on other applications.
  •  For many years, the importing process of DXF files had been very difficult because of the unavailability of specifications of the format. 
  • Presently the format specifications are available as PDF but this format is rarely used in AutoCAD applications.


  • We can use a range of programs to view/edit DFX files.


  • The ASCII DXF file is a complete representation of a drawing in ASCII text form.  Data is represented with numbers and strings of text that you can easily interpret using the specification document.
