AutoCAD is a software developed by AutoCAD way back in 1982 designed for Engineers, Architects and Designers. It is the flagship product of Autodesk and till date, there are not competitive products that can match AutoCAD.
AutoCAD was developed from a program called Interact, which was written in a launguage called (SPL) by Michael Riddle. The first version ran on the Marinchip Systems 9900 computer (Marinchip Systems was owned by Autodesk co-founders John Walker and Dan Drake). Walker paid Riddle US$10 million for this CAD technology.
When Marinchip Software Partners (later known as Autodesk) formed, the co-founders decided to re-code Interact in C and PL/1. They chose C because it seemed to be the biggest upcoming language. The C version was the most complex programs in that language. Autodesk had to work with a compiler developer, Lattice, to update C, enabling AutoCAD to run. Early releases of AutoCAD used primitive entities such as lines, polylines, circles, arcs, and text — to construct more complex objects. Since the mid-1990s, AutoCAD supported custom objects through its C++ Application Programming Interface (API).
The modern AutoCAD includes a full set of basic solid modeling and 3D tools. The release of AutoCAD 2007 included the improved 3D modeling that provided better navigation when working in 3D. Moreover, it became easier to edit 3D models. The mental ray engine was included in rendering and therefore it is possible to do quality renderings. AutoCAD 2010 introduced parametric functionality and mesh modeling.
The latest AutoCAD releases are AutoCAD 2013 and AutoCAD 2013 for Mac. The release marked the 27th major release for the AutoCAD for Windows, and the third consecutive year for AutoCAD for Mac.
