AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a computer-aided design (CAD) data file format developed by Autodesk [2] to enable CAD data exchange and interoperability between AutoCAD on different computing platforms.
The DXF is primarily 2D-based and its format is a tagged data representation of all the information contained in an AutoCAD drawing file, which means that each data element in the file is preceded by an integer number that is called a group code indicating the type of following data element.
The first release of the software started with version 1.0 in December 1982. [1] The software has been continuously updated since its initial release. AutoCAD opens documents with DWG compatibility as a "DWG file format version code" where the specific version code can be found by opening the .dwg file in Windows Notepad or any text editor program.
The LibreDWG project has resumed active development, including the addition of more recent .dwg and .dxf formats with version 0.5 in June of 2018. [12] The most recent release as of November 2020, version 0.12.5 includes read support for all DWG formats r13+, write support for r2000 DWG and read/write support for all r13+ DXF versions. [ 13 ]

DWF files (since version 6.0) are a ZIP-compressed container for the drawing files; despite the first few bytes of the file containing a DWF header, renaming a .dwf file to .zip will allow the component files inside to be viewed with archive compression software.
A man using AutoCAD 2.6 to digitize a drawing of a school building. AutoCAD was derived from a program that began in 1977, and then released in 1979 [5] named Interact CAD, [6] [7] [8] also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.
Analytical model can be created using the ribbon-based user interface, by editing the command file or by importing several other files types like dxf, cis/2 etc. The model geometry can even be generated from the data of macro-enabled applications (like Microsoft Excel, Microstation etc.) by using Macros.
