Drawing Interchange Format (AutoCAD). DXF is a file extension for a graphic image format typically used with AutoCAD (Computer Assisted Drafting) software. DXF stands for Drawing eXchange Format. Since its initial release in 1982, there have been many changes to the DXF file format specifications. For that reason, AutoDesk maintains a current list of DXF file format specifications. Depending on the software creating the DXF file, it can either be in an ASCII or a binary format. MIME type: application/dxf, application/x-autocad, application/x-dxf, drawing/x-dxf, image/vnd.dxf, image/x-autocad, image/x-dxf, zz-application/zz-winassoc-dxf. Learn more about .DXF files:
