AutoCAD 20.0 Download [Win/Mac]
AutoCAD is the de facto standard in the industry for professional 2D CAD. Its cross-platform availability, flexibility, and advanced features are unmatched by other tools.
What is AutoCAD?
AutoCAD is a software package used by architects, engineers, drafters, and other professionals to create 2D and 3D models. These models can be used to manage drawing projects, and create drawings and layouts for projects, including applications like architectural and mechanical design, product design, building design, survey documentation, mechanical engineering, power plants, manufacturing planning and management, and more. You can also use AutoCAD for creating surface models.
The most common way to use AutoCAD is by using a 2D drafting program called the AutoCAD program. Like most software packages, it can be used to create 2D and 3D drawings. Using AutoCAD, the user can enter a drawing project that will be saved to a file. The user can then modify the drawing by drawing, modifying, and deleting objects. The user can also rotate, scale, and move the objects within the drawing, which are stored in layers.
AutoCAD can also be used to create 2D and 3D surface models that are saved to and used in engineering and architectural design. You can create surface models as a representation of the object that needs to be engineered or designed.

Where does AutoCAD come from?
AutoCAD has its roots in early computer technology of the 1970s. In the early days of the computer age, AutoCAD was one of the first commercial packages used for drafting on the minicomputer. It was written by a team of software developers who were employees of a company called AEL Software, Inc. After the dissolution of the company in 1982, the development team formed Autodesk, Inc., which still maintains and develops the AutoCAD package.
AutoCAD History
Before AutoCAD was released, CAD was limited to use on large mainframe and minicomputers. The first computerized drafting system was introduced by PARC, an Xerox subsidiary, in 1972. PARC's AutoPAD was the first CAD program.
In 1975, AEL Software was formed, and the AutoCAD program

AutoCAD also includes a command line interface which may be used for automation or customization (see help for more information).
Most professional plug-ins are designed to work with a specific release of AutoCAD. A plugin will generally work with a particular version of AutoCAD only if it is specifically designed for the particular version. The application will usually offer a way to download updated versions of the plug-in. This allows for a program to be updated and keep working with a particular release.
Popularity
AutoCAD is the market leader in 2D drafting software. Its main competitors are the cross-platform Revit (by Autodesk) and Vectorworks (by Trimble). The US headquarters of AutoCAD is located in San Rafael, California.

Category:Technical communication toolsControlling the flow of water through a restricted pipe, e.g., a faucet pipe, is traditionally accomplished by having a user physically turn a knob that activates and deactivates an actuator valve. Although this technique is adequate for most applications, it is not particularly satisfactory when used in systems that are intended for children, the physically challenged, or other individuals who are unlikely to manually activate a faucet valve.
A first solution to this problem is to use a mechanical switch, such as a faucet actuation switch. A mechanical switch requires manual activation for the switch to be effective. In addition, once the switch is activated, it does not allow the user to return to the original state, e.g., turn off the water. Mechanical switches also typically do not include features such as multiple water flow rates, timed or sequential operation, or the ability to control operation of a faucet by means of a remote controller.
