AutoCAD , is a Logiciel of Dessin computer-assisted, created in 1982 by Autodesk. By installing CrossOver Office or Wine, it can also function under GNU Linux.

Although, at the origin, it was developed for the engineers in mechanics, it, today, is used by many trade associations. It is currently the software of the most widespread CAD in the world. It is a multidisciplinary technical design software:

Its success is especially due to the fact that it makes it possible the user to create his own menus and to develop applications thanks to its language Autolisp derived from Lisp and thanks to VBA. Reduced version, said LT (for Lap-Signal and not Light or Lite as one could think it) has however this facility, neither of the functions of drawing in three dimensions such as the voluminal or surface objects, nor of the programming; it makes it possible however to visualize them and it is however more reliable and more rapid that the full version, greedier in data-processing power.

The AutoCAD files carry the extension DWG and are organized in copies whose user can manage posting like certain properties. Since several versions, Autodesk tried to protect its format DWG by encryptant it to consolidate its position on the market. The consortium OpenDWG proposes tools making it possible many editors to read and write formats DWG.

The format DXF, initials of Drawing eXchange Format, is a format created by the Autodesk company being used to exchange files CAD or CAD between systems CAD not using the same format of native file. It was conceived in the beginning to represent the models 3D created with AutoCAD.

Autodesk also developed a format DWF intended for the publication of the drawings on the Web. The files can be read by means of a free diffused software (but nonfree). It offers functions of Zoom and displacement but does not allow the modifications. DWF is an initiative trying to compete with the format of ADOBE pdf for engineering which offers multi-layer functions and 3D and associated data for collaboration.

The various versions of Autocad (2000 to 2005) resemble each other much, so much so that the customer can wonder in what that is worth it the sorrow to make an update. Nevertheless, the version 2006 makes really notable improvements, like a help with the seizure of the distances, angles and coordinated as well as the dynamic blocks which make it possible in only one modifiable symbol by local handles to generate many alternatives, without having to create various blocks. Thus, a window (or a door) dynamic can have all wanted dimensions, thus avoiding creating all the windows of the catalog. Attention, the creation of the dynamic blocks is only realizable under the version Pro, version LT being satisfied to use them.

The success of AutoCAD saw being born various clones like IntelliCAD and BriscCAD, others strongly similar like TurboCAD and DesignCAD. AutoCAD is not necessarily the best reference, but from its general possibilities and its seniority, it largely dominates the field of small the CAD (approximately 70-80%). On the other hand, its possibilities 3D and of CAD or CFAO do not make of it an ideal software in these 3 categories. Moreover, its price can appear excessive compared to what its rivals propose (approximately 1400€ for version LT (2D) and 4000€ for the version Pro (3D)).
