AutoCAD Crack + Serial Key Download [Win/Mac] (Final 2022)
History of AutoCAD
AutoCAD was originally released in December 1982 as a desktop app running on microcomputers with internal graphics controllers. Before AutoCAD was introduced, most commercial CAD programs ran on mainframe computers or minicomputers, with each CAD operator (user) working at a separate graphics terminal. Prior to the release of AutoCAD, there were several attempts at creating a personal computer-based CAD system. The first was written by Jack Nutting and released as CAD-A. CAD-A was developed for the DEC PDP-11 minicomputer and ran on the TOPS-10 operating system. AutoCAD is currently marketed by Autodesk and is still sold as a desktop app on Microsoft Windows and macOS.
AutoCAD was one of the first commercial CAD systems, and many of its design features have been incorporated into other CAD systems.
System Requirements
AutoCAD is available for free for a variety of platforms and operating systems. Autodesk maintains a list of supported operating systems and versions.
Additionally, AutoCAD for Windows and AutoCAD for Mac are available as part of the AutoCAD subscription program.
Getting Started
To begin using AutoCAD, you need to download and install it on a computer, and download AutoCAD's file storage account onto another computer.
Connecting to a file
After you install AutoCAD and download the Autodesk Cloud storage, you can begin creating projects by uploading a file to the cloud. To connect to a file stored in the cloud, click the blue cloud icon in the bottom-right corner of your window.
Next, click the Storage tab, and choose your Cloud storage account.
After you choose your account, enter the file's email address, the file's URL, the name of the file, and click Connect.
If you are using a mobile device, you may be asked to download an app, or you may be prompted to sign in to your Autodesk account. To sign in to your Autodesk account, click the "Sign In" icon. If you are already logged in to your Autodesk account, you can continue with the steps above.
To access the file, click the file's name. The file can be opened or previewed with AutoCAD. To finish the project, you can exit or close AutoCAD.

Mobile apps 
AutoCAD is available as mobile apps and a web app. The mobile apps are available for iOS, Android, and BlackBerry 10 devices. AutoCAD Mobile enables users to view AutoCAD drawings, and annotate, draw, scale, and rotate them. The Autodesk Exchange Apps feature also provides a number of mobile applications, including AutoCAD Electrical, AutoCAD Civil 3D, AutoCAD Mechanical, AutoCAD Landscape, AutoCAD Speeddraw, AutoCAD Structural, and AutoCAD Manufacturing Applications for mobile devices. These can be used in conjunction with the desktop or mobile version of AutoCAD.
 Web 
AutoCAD is also available as a web application, which allows users to view drawings online, and also annotate, draw, scale and rotate them. These online drawings can be uploaded and viewed by others through the Autodesk Exchange website. The Autodesk Exchange Web App allows users to download files from the Autodesk Exchange website and view online drawings. 
AutoCAD R16 and AutoCAD LT 16 are the first editions of AutoCAD that support web browsers; previous versions of AutoCAD only supported Internet Explorer 8 or earlier.
AutoCAD Architecture
AutoCAD Architecture is a free 3D application that allows architects to design 3D buildings. AutoCAD Architecture allows architects to import and export architectural drawings in the GCS 2 format.
AutoCAD Architectural 3D is the architectural edition of AutoCAD, designed specifically for architectural design and publication. AutoCAD Architectural 3D lets architects create and edit 3D drawings and assemblies, as well as export and publish them.
Autodesk Architectural Fusion is the architectural edition of Autodesk Fusion 360. Autodesk Architectural Fusion allows architects to easily create 3D models using the same design tools they use for 2D CAD drawings. It includes the familiar 2D view and 3D editing tools from AutoCAD.
Universities
AutoCAD is used by many university design departments. In 2007, the University of Georgia, where students were taking more than 14,000 AutoCAD R14 license exams each year, issued a public challenge to all universities: "AutoCAD is perhaps the most widely used and accepted tool for technical drafting, but the number of high-quality AutoCAD exams taken by university students annually is limited." If students pass, they get a free

This invention relates to a two-step hydrogenation system for removing impurities from crude oils. More specifically, this invention relates to a hydrogenation system which first employs a hydrodesulfurization zone which reduces the sulfur content of a hydrocarbon feedstock, and which then reduces the sulfur content to less than 50 ppm by employing a hydrodenitrogenation zone which, in turn, reduces the nitrogen content to less than 10 ppm. The system is particularly useful for the upgrading of high sulfur and high nitrogen distillates such as vacuum gas oils, pyrolysis gas oils, straight run gas oils and the like. The invention is especially useful when applied to the liquid hydrocarbon feedstock, which is the preferred embodiment of this invention.
Hydrogenation is a well-known refining operation to improve the quality of crude oils, distillates and the like. By conventional processing, nitrogen is removed from the feedstock, which reduces the chances of pre-ignition of the feedstock. The nitrogen content of the feedstock is thereby maintained below about 10 ppm. In addition, the feedstock is usually made more stable for shipment by the addition of substantial quantities of distillate fractions having a boiling range between about 350.degree. F. and 1050.degree. F. and containing non-volatile hydrocarbon components, which is known in the art as "coking stability".
The hydrogenation of hydrocarbon feedstocks is usually carried out in multiple-stages with interstage separation of the feedstock.
