AutoCAD 2021 24.0 Crack Product Key Full [Win/Mac]
The advent of AutoCAD
AutoCAD was originally created as a desktop application running on the NGS (Net Generation System) operating system. NGS was developed by Digital Equipment Corporation (DEC) to provide powerful vector graphics capabilities to microcomputer users. The initial version of AutoCAD, AutoCAD R1, was released in 1983 for the personal computers running on NGS. At the same time, the first commercial CAD programs, such as Cad Tech Draw and AutoCAD, appeared, but they did not support the new NGS features.
With the introduction of AutoCAD in 1982, the world changed forever. Computer graphics became affordable to the average individual and businesses. AutoCAD became the flagship product for DEC's NGS and later the DECwindows product line. After some years of the successful operation of AutoCAD, the first major update to AutoCAD, version 2.1, was released in October 1985. Other product upgrades included the release of 3D Raster Graphics (1985) and PostScript (1987).
AutoCAD R2, the first version of AutoCAD available for the Apple Macintosh, was released in 1987. The release of AutoCAD R2 marked the beginning of a 30-year AutoCAD partnership with Apple Computer, Inc. AutoCAD is now a widely used software application in architectural and engineering disciplines.
The continued support and success of the AutoCAD product line relies on its licensing program, which began in 1985. Starting from the current version, AutoCAD is available to the general public at a reasonable price. Currently, the software can be purchased for a single license for $49, and multiple user licenses are available for an additional charge. A subscription to updates is available at a monthly cost of approximately $100 per user.
* AutoCAD 2018 (AutoCAD LT), Web App, and cloud services are not included in the Autodesk Planner subscription and require an additional annual subscription cost.
What is AutoCAD?
AutoCAD is a highly configurable and capable CAD application, designed for a wide range of users and applications. AutoCAD is a powerful tool that can be used to develop complex drawings.
The AutoCAD software interface is shown in Figure 1, below. It is divided into three main sections: the drawing area, the status bar, and the toolbars.
The drawing area, also referred to as the workspace, is the

In 2013, AutoCAD was extended to support a Direct X Application Programming Interface for Windows that allows third-party development for AutoCAD. This allows creating new products by third-party developers. The final release of this API, named Xapian, was released in 2015.
AutoCAD Civil 3D is an extension of AutoCAD available for use as a standalone application or as a plug-in. It is a native AutoCAD add-on for 3D architectural design and structural engineering. AutoCAD Civil 3D uses a Microsoft Visual Studio environment to create its applications. It can work directly with file formats such as DWG, DXF and IGES. Civil 3D runs on Windows platforms and is accessible from within the AutoCAD design environment.
AutoCAD Architectural Desktop (ADT) is a plugin that extends AutoCAD by providing tools for creating architectural designs and also supports 3D/CAD models.
AutoCAD WS (Web Services) is an API that supports web services. It was introduced in AutoCAD 2009 as an add-on for web applications such as websites that want to use the power of AutoCAD. Developers of web applications can use this API to customize the online experience, control the display, perform searching, retrieve information from a drawing, and render the contents to display on screen. It is available for the Windows, Mac OS X and Linux operating systems. The current version is AutoCAD 2010.
History
AutoCAD was first released in 1982. The first version of AutoCAD, AUTOCAD 2.0, was a DOS-based program and was created by John E. Anderson. It was the first CAD application of its time to combine a drawing program and a database.
AUTOCAD 3.0 was released in 1991. It was a Windows-based application and created the first native Windows application for AutoCAD. It became the first CAD program to create 2D and 3D drawings simultaneously.
AutoCAD 3D was released in 1992 as AutoCAD's first 3D application. It was initially released as a separate program from AutoCAD 3.0, but was integrated into AutoCAD 3.0 and 5.0.
AutoCAD 4.0 was released in 1995 and introduced three-dimensional modeling.
AutoCAD 5.0 was released in 1997 and introduced multi-platform development. It also introduced block diagrams and templates.
