AutoCAD 20.0 Crack + Free [Latest] AutoCAD is used for the design of ships, bridges, tunnels, roads, and other structures, including buildings. AutoCAD is also used for line-drawing and drafting in smaller quantities, such as architectural plans and blueprints, engineering, mechanical design, custom model-making, and other purposes. AutoCAD is also used to build 3D models in a virtual environment, similar to building a 3D model with a 3D printer, to view models in a virtual environment, such as computer-aided design (CAD) drawings, and to create animations of engineering models, such as cars and engines. History and background [ edit ] AutoCAD started development as Topographic Sheet Generation System (TSGS), in 1975, in response to a requirement from the Pentagon to develop a system capable of generating blueprints and the digital equivalent of blueprint drawings. TSGS was developed at a time when microcomputers were coming into their own. Computers with powerful internal graphics systems (intelligent graphics controllers) had become affordable, and the capability to connect multiple graphic terminals (graphics terminals) to a single host computer was emerging. Topographic Sheet Generation System was written entirely in assembly language and could use a disk-based storage scheme. At the time, mainframe and minicomputer computers were being replaced with desktop machines, and the ability to connect multiple graphic terminals to one computer terminal was an advantage in sales because computer users were becoming more familiar with the process of working at a terminal. A year later, Topographic Sheet Generation System was completed, and the program was used to generate blueprints for a US Army camp. In 1978, Topographic Sheet Generation System was re-engineered and re-coded as the Topographic Sheet Generator (TSG), as it was understood that the program would need to generate more complex drawings. In early 1980, the Defense Advanced Research Projects Agency (DARPA) was looking for a CAD system, and TSG was one of three programs considered for the contract. The program was evaluated by the Defense Technical Information Center (DTIC), which was funded by DARPA and was responsible for evaluating all information technology resources of the US Department of Defense. The assessment produced a report in 1980 that recommended TSG. During the next two years, TSG was improved to meet the needs of the Department of Defense. In the summer of 1982, the US Army Research Lab (ARL) published the final version of TSG, with AutoCAD 20.0 Crack Free For PC Customization AutoCAD is a powerful drawing program. Its API allows developers to create user interfaces, utilities, and add-on modules that assist in the creation, editing, drawing, and publication of 2D and 3D drawings. While, at its core, AutoCAD is a 2D drafting application, it also includes capability for creating and manipulating 3D drawings. 3D capabilities include the ability to insert and delete objects and curves as well as the ability to rotate, tilt, and move objects. AutoCAD is a windows-only product. However, in recent years, more Unix-based software has been made available. In order to allow some low-level manipulation of these features, they are implemented in terms of objects and methods of AutoCAD, and can be accessed through the "customization" tools. In addition, a command line interface is available for users without the AutoCAD program. Customizations Macro creation AutoCAD allows non-programmers to create macros. Macro definitions are written in either Visual LISP (VLB) or Visual Basic (VB) language and stored in a collection called the Workbook. Once a macro has been created, it can be called by dragging and dropping it onto the drawing window, but also by a click on a toolbar button. There are two basic types of macros in AutoCAD: user-defined macros and predefined macros. In general, a user macro can be much more powerful than a predefined macro, and can be written in Visual LISP or VB. User-defined macros have functions associated with them that are called when the macro is executed. User-defined macros can be triggered by selecting a line, surface, group, or 3D object on the screen. If the function of the macro is associated with a single object, the macro can be triggered when the object is activated. This is typically done when a line, surface, group, or 3D object is drawn or modified. A macro can have parameters which allow the execution of the macro with a specific set of values. These values can be used in a formula to calculate a specific result, or can be used as a variable for a formula to be reused in other macros. User macros have access to the context of the drawing and objects that are contained within it. Therefore, they have the ability to access and manipulate objects other than just those that they are related to.
