AutoCAD Crack + Activation Code With Keygen

Overview
AutoCAD is used for designing many kinds of products, from architectural models to mechanical designs, to electrical schematics. Because AutoCAD is a commercial product, its cost may be prohibitive to some home and student users. For this reason, Autodesk has released free AutoCAD versions for non-commercial use.
Autodesk released AutoCAD in the late 1980s to complement its personal drafting program, AutoCAD LT. In addition to using the AutoCAD software to design three-dimensional models of objects, AutoCAD users can use a program called Inventor to create parametric models. Modeling for AutoCAD is discussed in the Parametric Modeling article.
In January 2008, Autodesk announced a new version of AutoCAD, AutoCAD 2008, that included new features and capabilities. The 2014 release, AutoCAD 2014, included many new features, a new user interface, enhanced hardware support, and significant performance improvements. The 2014 release also included significant new functionality in the form of a solid-modeling component, which is discussed in the article.
Autodesk also released a free (in essence, student) version of AutoCAD called AutoCAD LT 2004, which uses the same source code as AutoCAD LT and requires an Internet connection to download AutoCAD updates. AutoCAD LT 2004 is available for Microsoft Windows and Apple Macintosh operating systems, and like AutoCAD LT can be run on computers that lack graphics hardware.
A free version of AutoCAD 2012 is available for both Windows and Macintosh operating systems.
History
AutoCAD history
AutoCAD was one of the first CAD software products, and is still sold by Autodesk. When it was first released, AutoCAD was primarily used to create architectural and mechanical designs. Early versions were software with a command line, or console, that only let users create simple geometric shapes. As AutoCAD evolved, designers began to use it to create industrial design concepts, electrical schematics, and mechanical parts.
AutoCAD was originally created by Joe Perez and Jim Gray. Originally called AutoLisp, the software was developed for the Xerox Alto personal computer in 1975. Perez and Gray envisioned a software product that would allow users to create two-dimensional drawings on a personal computer, a vision which Autodes
