DXF是AutoCAD DXF（Drawing Interchange Format或者Drawing Exchange Format）的简称，它是Autodesk公司开发的用于AutoCAD与其它软件之间进行CAD数据交换的CAD数据文档格式。

DXF于1982年12月作为AutoCAD 1.0的一部分首次面世，用于从未公开的AutoCAD内部文档格式DWG的一种精确表示。目前Autodesk在它的网站上公布有从1994年11月发布的AutoCAD Release 13到2006年3月发布的AutoCAD 2007的DXF规范。

AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a CAD data file format developed by Autodesk for enabling data interoperability between AutoCAD and other programs.

DXF was originally introduced in December 1982 as part of AutoCAD 1.0, and was intended to provide an exact representation of the data in the AutoCAD native file format, DWG (Drawing), for which Autodesk for many years did not publish specifications. Because of this, correct imports of DXF files have been difficult. Autodesk now publishes the DXF specifications as a PDF on its website.
