what is autoCAD ?

AutoCAD is a computer-aided design (CAD) software program that is used for creating 2D and 3D designs and models. It was first introduced by Autodesk in 1982 and has since become a widely used software program for various industries, including architecture, engineering, and construction.

AutoCAD allows users to create detailed drawings and designs using a variety of tools and features, such as line, circle, and rectangle tools, as well as advanced features like parametric constraints and 3D modeling tools. The program also supports customization through the use of macros, scripts, and plug-ins, which can help to automate repetitive tasks and improve workflow efficiency.

AutoCAD has become an essential tool for many professionals in the architecture, engineering, and construction industries, as it allows them to create detailed designs and models, perform calculations and analysis, and communicate design concepts with clients and colleagues. It is also widely used in the manufacturing industry for creating 2D and 3D models of products and components.
