What is the DXF format

DXF (Drawing Exchange Format File)

AutoCAD DXF files (also known as Drawing Interchange Format or Drawing Exchange Format) were developed by Autodesk to enable the exchange and use of data between AutoCAD and other similar programs. The intention behind the format introduced in 1982 was the ability to reproduce data in the AutoCAD-native DWG format and to facilitate the exchange of files. This process was difficult until the specifications were published in PDF format. DXF and DWG files would be more prominent in the specification release and would be more useful if DFX files could support the more advanced CAD elements. AutoCAD's decline in popularity has also reduced the requirements for application-independent formats.

Technical details of DXF files

DXF files allow the user to open the files with simple text editing programs and applications. The files have a formatting that includes various sections, which is common with other related files. Such elements within the format are: headers (property information), classes, tables, entities, blocks and thumbnails. The marked data within the DFX file enable the identification of data interpretation methods. The format of the tagged data also means that each data element is preceded by an integer, known as a group code, which indicates the order of the data and the meaning of the data elements for certain objects.
