AutoCAD flagship company Autodesk, a software designed to help Mac computers used by designers, architects and engineers in the two-dimensional and three-dimensional models of integrated levels or network is used. Before designing with the help of computers, the designers had to work with tools such as design boards, pencils, automata, rulers, compasses and tunes that were much more limited than modern tools like AutoCAD. Since 1982, when the first version of AutoCAD software was introduced to the market, it became the most widely used computer design tool due to the advanced features of automotive and computer design. This software is currently the most widely used industrial design and cartography software that has over 100 million users worldwide. This software engineers to the Mac it so they can implement their ideas in mind and to help free three-dimensional drawing, design and documentation of their SMART products. The range of capabilities of this software is so broad that it is not limited to a specific field and industry, and in almost all cases designing and drawing 3D models in the fields of electronics, civilization, architecture, mapping and modeling is applied. Over the years, Autodesk has released special versions of this software for many engineering disciplines, including AutoCAD Electrical, AutoCAD Mechanical, AutoCAD Architecture, and so on.
