AutoCAD is a Computer-Aided Design (CAD) drafting software, marketed by Autodesk. It is a commercial 2D and 3D drafting software. The AutoCAD software is used for several applications, including floor plan design, blueprints for buildings, bridges, chip design, etc.
The AutoCAD was designed to help the users to achieve the realistic appearance of their projects. It is used by professionals in various industries to enhance their design, which increases the quality and productivity of their product. It has also increased the speed of manufacturing of the parts.
What is AutoCAD?
The commercial CAD programs were used before the development of AutoCAD. The AutoCAD was run on microcomputers with an internal graphics controller. The commercial CAD programs ran on the minicomputers or mainframe computers, where each CAD operator worked at a separate graphics terminal.
The AutoCAD software is available in various languages, namely, English, Italian, Spanish, German, French, Spanish, Albanian, Polish, Russian, Czech, Hungarian, Chinese Simplified and Traditional, and Brazilian Portuguese. The AutoCAD has developed for various programs and fields.
History of AutoCAD
The Interact CAD was the first program began in 1977 and released in 1979. The AutoCAD was derived from the Interact CAD program, which is also referred to as MicroCAD in early Autodesk documents. It was written before Autodesk formation.
The co-founder of Autodesk was Michael Riddle.
The first version of AutoCAD by Autodesk was demonstrated in 1982 and released in December, in the same year. It also supported CP/M-80 computers. By the year 1986, in March, the AutoCAD became the most effective CAD program worldwide.
The 2020 version was marked as the 34th version released by the AutoCAD for Windows. The 2019 version was marked as the 9th consecutive version for the MAC. The common extension for the file format in AutoCAD is .dwg.
The DXF file format has become the de-facto standard for 2D drawing exchange and CAD data interoperability.

AutoCAD Display
The 2D and 3D drawings are created on the given screen. The display contains all the tools and icons which make the process to create any drawing. There are particular shortcuts for icons.
The drafting is a technology for the design, which replaced the manual drafting with the automated process.
Some of the icons are different on the 3D display than the 2D display.
The icons of AutoCAD are present on the Ribbon Panel and 3D Modeling
3D Basicsthe Status bar.
- 3D Modeling
- 3D Basics
The 3D Modeling includes some advance icons, while 3D Basics includes basic icons.
The display of AutoCAD 3D Modeling is shown in the image below:
