AutoCAD 20.1 Crack Activation Download [Latest]
History and Usage
AutoCAD Free Download was originally developed by a company named CAD Associates as an external graphics terminal (EGT) for a microcomputer, the Apple II, with the first commercial release in October 1982. The application (and also the microcomputer) was named AutoCAD, a play on “autocad”, which was the way CAD operators communicated during the “autocad tape era” in the late 1970s.
CAD Associates later partnered with Autodesk to market the software (now known as AutoCAD) for the Apple II and IBM PC platforms, and it has remained the most popular CAD program ever.
AutoCAD initially ran on a Motorola 68000 processor and the Apple II, and later a Motorola 68020 processor and the IBM PC. The 68020-based version came to dominate the market, with some versions offering almost twice the speed of the 68000 version. AutoCAD runs on a variety of Macintosh computers, such as the Power Macintosh G3 and G4 series, and the Power Mac G5 and G6 series.
AutoCAD’s predecessor was Microcad Plus (released in 1980), which was based on a MIT-licensed drawing program called P.E.G.S. (Programming Editor General System). It was released in November 1980 by CAD Associates, Ltd., for the IBM PC, Apple II, and the Apple Lisa, and the author in his book Computer Graphics from 1979 on cites CAD Associates’ P.E.G.S. and AutoCAD as “two of the most interesting innovations in computer-assisted design during the 1980s.”
For a long time, AutoCAD was sold only as a stand-alone app. Originally written in the assembly language of the 68020 processor, it was rewritten in more optimized C++ code, and was ported to other platforms, including the Macintosh and Linux. In 2005 the app was rewritten in an object-oriented architecture with DirectX/OpenGL graphics acceleration. AutoCAD LT and AutoCAD Browser, as well as AutoCAD Mechanical, AutoCAD Electrical, and AutoCAD Architecture, were released for various platforms, providing the ability to use the same program to create drawings on a desktop computer and also on mobile devices, like a smartphone or tablet computer.
In the past, companies wishing to release an AutoCAD version had to buy a non-exclusive license to the software. The first

A block is a set of information about a single line, area, or multiline object. The Multi-block system provides the ability to separate blocks into distinct sections, and then to link them together by referencing them one by one. Blocks can be linked in order to produce a cohesive drawing, or any combination of the individual blocks can be linked to each other in order to produce a complex drawing.
AutoCAD Crack Mac is linked to a range of platforms, including Microsoft’s Internet Explorer (IE), Apple’s Safari and Google Chrome browsers. When executing on the IE browser, only specific AutoCAD Product Key 2012 R1 commands can be activated and used. The 2016 version is linked to the latest Microsoft Windows operating system.
The AutoCAD Full Crack 2013 introduces a new layer of abstraction called Integrate for CAD systems. When a layer is a drawing of a drawing, the only layer is the file. Now the layer is a set of elements and symbols. Each layer can be viewed as a library of symbols.
There are 5 types of layers.
Visual Layers: Also called “Visible” or “VisLayers”, a layer can be divided into sub-layers. A sub-layer represents a sub-area or object in the same layer. When a block is drawn in a sub-layer, the sub-layer is added to the layer’s geometrical area. The sub-layer symbols are shown only when you add the layer, but they can be hidden or shown using the Layer Properties dialog box.
Hidden layers: These layers are not shown on the screen, but they can be manipulated and displayed in the Layer Properties dialog box.
Hidden layers are useful for hiding layer contents. For example, if you do not need a layer in a drawing file, you can make it hidden so it is not shown when the drawing is opened.
Mask layers: A mask layer is the union of all symbols in a drawing layer. A mask layer may be a whole or partial drawing.
Parameters: Parameters are used to display or hide the symbols in a layer.
Templates: A template layer is used to display a set of standard drawings. A template is just like a layer, but it is saved in a different file type. To show a template, you must enter a filename for it in the Template Name dialog box.
The Integrate system also allows users to attach or detach blocks and create
