AutoCAD 2020 23.1 Crack Full Product Key Free [Mac/Win] [2022] Contents show] Anatomy of AutoCAD Product Key AutoCAD was first released in 1982 on the Apple Macintosh II and in 1984 on the Apple IIGS.[1] It was a major milestone in the early history of computer-aided design, and it ushered in the era of the CAD/CAM (computer-aided manufacturing) industry. AutoCAD introduced several innovative features to CAD, including: Automatic boundary detection; that is, drawing edges automatically around the modeled object; Computer-aided drawing (CAX), a file format standard that would become widely adopted for importing and exporting 3D geometry; Desktop publishing and mail merge capabilities. AutoCAD is a commercial desktop CAD system that is designed to work with a commercial CAD library. The primary benefits of AutoCAD over other CAD tools are speed and ease of use. History In 1982, artist and engineer Charles Grier worked for a small contractor that did architectural CAD. One day, Grier saw a presentation on computer-aided drafting and 3D modeling. Grier became very excited about this new technology and decided to design a tool that could make 3D modeling accessible. Using a special-purpose Apple IIc running Macintosh System software 3.0, Grier sketched out the first version of AutoCAD. Grier chose to use a desk-top approach instead of a terminal model. This made AutoCAD easy to use and fast. The first version of AutoCAD was released on December 16, 1982.[2] Sales of the Apple IIc were good, and the company had a profitable second quarter. However, the first model of AutoCAD was not a success. Because of design limitations, the system had a steep learning curve and was not sufficiently powerful to handle large files. For example, it took hours to load a 3D model. Grier believed that the more powerful computers of the future would be able to handle large 3D models, and that the market could expand if the software was redesigned for that platform. Between 1982 and 1984, Grier designed four more versions of AutoCAD, which he released as a series of alpha versions. A series of beta and final version releases occurred from 1984 to 1988. The final version of AutoCAD was released on the Apple IIGS on March 23, 1984. Grier incorporated many of the user suggestions, and created a much more powerful and user friendly system that was AutoCAD 2020 23.1 ObjectARX ObjectARX provides standard AutoCAD API. The object ARX (obj ARX) is a C++ class library which provides the same object oriented programming functionality as a similar object oriented programming framework in AutoCAD (i.e., by replacing the graphics objects in the built-in API). The ObjectARX library is provided by Autodesk for use in developing add-on products. In particular, ObjectARX is used to create development tools such as CAD plug-ins, scripts, macros, and batch files. AutoCAD's DXF format is an exchange format similar to the BMP format. This facilitates exchanging and importing of drawing information. Plug-ins AutoCAD has a large number of add-on products available on the Application store. These products are categorized as: plug-ins, add-ons, extensions, AutoCAD EVA's, enhancements, add-ons, and AutoCAD EVA's. AutoCAD's plug-ins allow a user to extend AutoCAD's functionality with specific features. AutoCAD's plug-ins are available to both retail users and academies. Symbols and symbols Symbols are graphical symbols which can be placed in the drawing. Symbols have the ability to be scripted and automatically updated when changes are made to the objects in a drawing. They are the main difference from blocks. An Xref or cross reference, also known as a cross-reference, is a reference that relates two other objects. These objects can be in the same drawing or in different drawings. The effect of a cross-reference is to keep an object and its related information (object ID, drawing reference, cross-reference, placement, coordinates, and other properties) together when the original object is moved. Large objects AutoCAD has the ability to handle large objects and uses the same methodology as most 3D CAD packages. Meshes Meshes can be used to define surfaces in a 3D drawing. They can be smooth or textured. Meshes can be created in AutoCAD with a standard polygon or with more complicated 3D shapes. Meshes are often used to create many of the surfaces in a model. Add-ons An add-on (or extension) is a package of AutoCAD tools that is designed for specific purposes. It may include capabilities such 5b5f913d15 AutoCAD 2020 23.1 Crack + License Code & Keygen Free Download [Mac/Win] (Final 2022) Before Test ```js setup({ webGL: true }) ``` What's New in the?
