The software has been the subject of multiple patents. The first version of AutoCAD was based on Simplex 3D, a collection of graphics primitives called "splines". AutoCAD's algorithms and functions derived from later versions of Simplex 3D. Autodesk acquired the Simplex Corporation in 1996, and then discontinued Simplex 3D in 1997.
There are three editions of AutoCAD: AutoCAD 2002, AutoCAD LT, and AutoCAD LT SP1. The latest edition of AutoCAD LT is released every two years; the most recent version was AutoCAD LT 2016 SP1. AutoCAD is also available for mobile devices, as a mobile app and a web app.
AutoCAD has become the standard of the drafting industry, due to its high versatility and the quality of its output. At first a simple drafting tool, it has evolved into an application with dozens of tools. AutoCAD has replaced paper-based drafting as the standard in the industry. The current version is AutoCAD 2017.
History
On May 9, 1987, Autodesk entered the CAD market with the release of AutoCAD, which quickly became a success and the standard for drafting software. In January 1999, the company released AutoCAD 2000, which was bundled with the company's popular drawing program Inventor. In January 2000, Autodesk released AutoCAD 2000 Standard Edition, which was licensed and purchased for $600 and later for $1,200.
Autodesk launched AutoCAD LT in 2001, which was designed to be a more cost-effective version of AutoCAD. In 2006, the company released AutoCAD LT 2010, a major update of AutoCAD LT. In March 2007, Autodesk launched AutoCAD WS, a Web-based version of AutoCAD, and released AutoCAD WS 2011 in September 2007. In 2009, Autodesk released AutoCAD 2010, which was based on AutoCAD WS 2010, and introduced the term "Revit" for the first time.
Autodesk acquired Macromedia in 2005 for its Flash-based animation tool Director and the Flash plugin for AutoCAD, which is also available for non-Windows operating systems.
In January 2012, Autodesk acquired SceneDoc, a developer of a diagramming, modeling, and rendering

History 
AutoCAD Cracked Accounts was first developed in 1987 at the headquarters of Autodesk in San Rafael, California, where it was developed with Microsoft AutoLISP for the Macintosh as the software base.
The first release of AutoCAD was in January 1989 and supported the Macintosh platform only. In 1991, the company introduced a development environment for Windows, which allowed users to create programs for the first time on Windows computers.
The AutoCAD name was changed in 1992 from AutoCAD to AutoCAD LT, which was the abbreviation for Lead Tradesman's Assistant. AutoCAD LT was a program for the DOS, Windows and Macintosh platforms and sold at a reduced price. It supported the first release of AutoLISP (AutoLISP 1.1) and several other languages. It supported the export of DXF files.
AutoCAD LT was popular, with over 150,000 registered users, but the developer/publisher, Micrografx, collapsed in 1995 due to financial problems, leaving many users without a product. In early 1996, Autodesk acquired the rights to AutoCAD LT and announced in August 1996 the release of AutoCAD LT Classic for the Macintosh platform.
The initial product releases were first available for use by companies as CAD/CAM systems, including chip packaging, semiconductor fabrication, rapid prototyping, mechanical engineering, and industrial design, as well as architectural design.
In 1996, Autodesk released the first version of AutoCAD for Windows. This was the first version of AutoCAD to include the xref tool that was first introduced in 1987. The xref tool allowed users to see the entire drawing file rather than just parts of the drawing file.
The next significant change in AutoCAD was the introduction of TrueSpace technology in 1997. TrueSpace was developed by Autodesk and introduced in AutoCAD R13. TrueSpace allowed designers to remove the geometric grid and use the data stored in the drawing file to determine the actual drawing size. It also allowed designers to move the paper to make the most out of the space they were working in.
In 1998, Autodesk released AutoCAD R14. AutoCAD R14 added the ability to load and store dimension and project information within the drawing file. AutoCAD R14 also featured the ability to draw any part of the drawing at any size. This was done with the use of a parametric system that allowed
