AutoCAD is CAD software – computer aided design or computer aided design – created and marketed by Autodesk, Inc. since 1982. It is mainly used for the elaboration of technical drawing parts in two dimensions (2D) and for the creation of three-dimensional models (3D). In addition to the technical drawings, the software has been making available, in its most recent versions, several resources for visualization in different formats. It is widely used in architecture, interior design, civil engineering, chemical engineering, mechanical engineering, geographic engineering, electrical engineering, and various other branches of industry. AutoMAP is currently available in versions for the Microsoft Windows and Mac OS operating system, although versions for UNIX have already been commercialized.
From version R14 (published in 1997) it enhances the expansion of its functionality through the addition of specific modules for architectural design, GIS, material control, etc.
Another striking feature of AutoCAD is the use of consolidated programming in an interpreted language, known as AutoLISP (derived from LISP language) or a variation of Visual Basic that allows customizing routines and commands.
It also interprets sequences of common commands written in text files, usually with the extension .scr loaded through the script command, these are not related to the lisp language, although they may also contain this code. //
Its peristaphic commands are Osnap and Ortho, although centerings in osnap are added with each update, it was noticed that when we draw a circle or arc with the ortho command on, there may be unevenness in the circumference line, causing the circumference to not be smooth . This bug has been noticeable since the K29 version released in 2010.
AutoCAD Version 1.0 (Release 1.0) - December 1982
December 82 Autodesk Releases AutoCAD v.1.0 (R1). The R1 specification did not exist, it serves only as a reference.

AutoCAD Release 12.0 - June 1992
June 92, AutoCAD Release 12 for MS-DOS or UNIX appears. With more resources in 2D, it establishes itself as a very popular platform all over the world. 3D features become a module sold separately as 3D AME, the adoption of dialog boxes for functions previously accessible only by the command line makes it easier to work with
AutoCAD Release 12.1 - March 1993
March 93, AutoCAD Release 12 For Windows appears, easier to customize, with a floating box of icons for accessing the most used commands.
AutoCAD Release 12.2 - November 1993
November 93, AutoCAD LT For Windows appears, which is basically the same as AutoCAD R12, but with fewer features, aimed at small users looking for a low-cost CAD program.
AutoCAD Release 13.0 - December 1994
December 94 AutoCAD Release 13 appears. Initially it was for both MS-DOS, Windows and UNIX, but what was supposed to be a multipurpose program caused a big headache for users, as it was the most unstable AutoCAD of all, but with great advancements such as the toolbar with quick access functions, layer functions (such as on/off), which used to be just a dialog box or command line, the long-awaited feature of importing pictures in GIF, TIFF, BMP formats and JPG and being able to work with vector and raster images at the same time, the use of complete texts and not just individual lines (MTEXT), and TrueType fonts increased the options and spell check were some of the innovations. Autodesk decides to unify the release of its major version with that of its simplest program AutoCAD LT R13.
AutoCAD Release 13.1 - October 1995
October 95 AutoCAD Release 13 for Windows appears, with a specific version for Windows 95 it became more stable. But many users still preferred the R12.

March 97 AutoCAD Release 14 for Windows appears. The DOS and UNIX version ends. Powerful, offering the stability of R12 and the facilities of R13, it is the most used platform in the world, dominating close to 70% of the world CAD market. Although 3D resources have evolved a lot, Autodesk begins to direct 3D users to more specific tools such as Autodesk Mechanical Desktop already in its version 3, but the evolution of 2D work tools does not stop evolving, selection modes are simplified, new commands such as: Autotrack (Osnap becomes more interactive) the use of the F3 key to turn OSNAP on/off, the plotting system also improves. It is possible to store the plot settings in an external file facilitating standardization. A single dialog box appears to configure the system and preferences among other improvements.
AutoCAD Release 14.1 - June 1998
In June 98, AutoCAD Release 14 appeared in Portuguese. But experienced AutoCAD users were not interested in the version, as they were already used to the commands in English, adding to that a dubious translation, such as: the OFFSET command, which makes parallel copies, had the name: COPPAR; the ARRAY command, which makes multiple copies, was called ARRAY. For starters it would be a good option, but very few companies were willing to buy it.
AutoCAD 2000 (Release 15.0) - March 1999
March 1999 Autodesk releases AutoCAD 2000 (Release 15) as a natural evolution of the most powerful R14 of all versions, but the previous version of AutoCAD is so efficient that most companies did not upgrade, the main highlights are on account of the plot where the parameters are recorded in the drawing itself, the option to create as many layouts as necessary with different parameters, the DDMODIFY command disappears and the PROPERTIES command appears, much more complete, being able to change all the parameters in the same place , the DESIGN CENTER also appears, which allows searching and importing STYLE’s, BLOCK’s and LAYER’s of the drawings without opening them. And the possibility to open several drawings at the same time.
