AutoCAD 20.1 Crack + Torrent PC/Windows [2022-Latest]
Work is completed by a user using drawing tools and commands, which are executed using a mouse or other pointing device. Cracked AutoCAD With Keygen can be used on two- or three-dimensional (2D or 3D) construction drawings, drafting architectural drawings and exploded diagrams, land planning and zoning drawings, multi-view drawings, etc.
The focus of AutoCAD is on 2D drafting, yet it is used for 3D modeling by architects, engineers, model builders and computer-aided manufacturing (CAM) users. In many countries, the use of CAD/CAM technology is referred to as CAE (Computer Aided Engineering), an abbreviation that was coined by James D. F. Spink in 1986. It is also a generic term that applies to any CAD/CAM software or an "end-to-end" package. [1]
History [ edit ]
In 1982, The Michigan Instruments Corp. (TMI), a small technology company in Lexington, Kentucky, invented the Graphics Display Editor (GDE), which allowed a microcomputer to display graphics. The TMI GDE was a frame buffer that could be connected to an external monitor and printed directly using a dot-matrix printer or to a computer graphics terminal. The TMI GDE used vector graphics, which are scalable graphics elements like geometric lines, circles, arcs and polygons, and were drawn with a mouse or drawing stylus.
One day, an engineer in TMI's Computer Graphics division, Philip R. Burdette, found himself writing a little program to test the GDE's graphics capabilities. The program was very simple: two circles on a black screen were meant to turn green when they got close to each other, and red when they got farther apart. Unfortunately, they seemed to get redder and greener instead. Burdette tested his new little drawing program on other TMI graphics boards and found that it was working the same way on every board. He asked a colleague in the CAD department, Chuck L. Irwin, if he could help.
By the end of the day, the TMI GDE program was working well on the majority of TMI's graphics boards, but was not working at all on the TMI 200, a microcomputer with a 4 kilobyte random access memory (RAM) and a Motorola 68000 microprocessor. Irwin checked the instruction set reference manual of the TMI 200 and found that it did not support the primitive functions

User interface 
AutoCAD Download With Full Crack runs on most major platforms: Microsoft Windows, macOS, iOS, and Android.
AutoCAD supports many different windows and frames. For the majority of its features, the UI is modal. In other words, when you have the application open and in use, it will be the only thing you can interact with. If you attempt to open a new application, it will not be open until you exit AutoCAD.
The windows which AutoCAD supports vary in style and functionality. The ribbon-style interface is popular with AutoCAD users. The large-area windows can be used to increase the size of the user interface. The docking tool window, present on the right side of the screen, may or may not be docked, providing additional access to drawing views. The split view allows a user to view two drawings at once.
AutoCAD 2012 introduced the tabbed window. Each tab is a view of a different file type.
 Icons 
AutoCAD includes many icons, used for various commands and features of the software. Most of these are either geometric (colored squares, circles, triangles, etc.) or decorative (gradient fills, banners, text, etc.).
The software also uses icons, such as the graphics mark and the grid. The most common graphics mark in the user interface is the magenta rectangle, denoting the active drawing. When the user moves the cursor, the "active" drawing changes color to a magenta color. When all drawings are highlighted and the user moves the cursor outside the drawings, the shape will change from magenta to an inverse color, denoting the highlighting of all drawings.
Grid
When the user is working with a drawing, an invisible grid is displayed below the active drawing. This invisible grid, commonly known as the "paper grid", is used to set the units and measures to a standard set of values. As the user moves the cursor, lines will automatically appear connecting the cursor to the objects on the paper grid. Some users will set units and measures (e.g., millimeters, feet, yards) on the paper grid before starting a drawing, in order to help avoid common errors.
There are several ways to move the cursor across the grid. These include direct manipulation of the grid by clicking and dragging. The grid can be dragged to a new location, or the user can click and drag on the screen and the grid will follow the cursor. The grid
