A new study from software analysis firm Gartner found that AutoCAD is the most-used 3D CAD program in the world, second only to AutoDesk’s AutoCAD LT, which is used by architectural and engineering firms to prepare building plans. Around 38% of surveyed companies have a license for AutoCAD, while a further 14% indicated they were using AutoCAD LT and that they would be upgrading their licenses.


Early development

AutoCAD was developed by a company founded by Dr. Ray Orbay and Dr. Ed Feenberg in 1980, called New Forms Software Corporation. The name of the company was changed to Autodesk, Inc. in 1985, when New Forms and the company that they worked for had been merged into Autodesk.

AutoCAD 1.0 was released in 1982, and was for the Apple II and the IBM PC compatibles. It was compatible with DraftSight, an early raster graphics system, and was one of the first CAD programs to support 3D modeling.

A beta version of AutoCAD 2.0 was released in August 1983, running on the Apple III and the IBM PC. In October 1983, Autodesk was bought by the University of Utah for $5.7 million. Shortly after the sale, Autodesk released AutoCAD 3.0 in December.

AutoCAD 4.0 was released in December 1985. The first version of the Windows-compatible AutoCAD 4 was released in September 1986.

AutoCAD LT, released in April 1987, was an add-on module that allowed AutoCAD to be run on low-end computers, including the HP LaserJet, which were not powerful enough to run the full AutoCAD. This was the first real step toward what would be the future of CAD, with a desktop CAD suite that could be used anywhere, even on low-end computers.

In December 1987, Autodesk introduced Architectural Design Application (ADA), an architectural design and documentation software application that competed directly with Autodesk’s AutoCAD 4.0. Architectural Design Application was the first commercially successful add-on module for AutoCAD.

AutoCAD LT (and later versions) gained the ability to run on minicomputers, including the IBM PS/2, when the Microsoft Windows graphics interface was extended to support color and Windows-specific drawing techniques. The first release of AutoC

F. A. Viewer is a program to view 3D objects in 3D.

In addition, AutoCAD is the application used in the Dynamic Input Editor for navigating models.

AutoCAD also allows printing output of drawings, including CAD drawings, such as vector graphics, 3D drawings, and geometry. Additionally, the interface includes a scripting language, VBA, and Microsoft Office VBA Automation.


AutoCAD LT (formerly AutoCAD Cross-Platform) is a cross-platform version of AutoCAD and VectorWorks for Windows and macOS (for Mac OS 10.6 or later), a Unix-based variant of AutoCAD (Linux, Solaris, AIX, HP-UX), and an EDA-related licensed derivative of AutoCAD for Linux, AIX, Solaris, and HP-UX. It is available in both stand-alone and integrated product configurations. AutoCAD LT is a cross-platform solution (Windows and macOS) that is based on the AEC industry standard: The 3D Systems Generic Database. It is also an end-to-end application used in the Dynamic Input Editor for navigating models.

AutoCAD LT is a user-friendly, affordable solution for the design and delivery of visual communications. It includes all the tools and functions of the Windows-based AutoCAD application, but can be used with 3D and 2D design projects on a variety of desktop and mobile platforms.

AutoCAD LT provides cross-platform capabilities, so users can work directly in AutoCAD LT on their Windows or macOS computer and share design data and project files with users on a wide variety of platforms.

Enterprise Data Center (EDC)

AutoCAD Enterprise Data Center (AutoCAD EDC) is the server component of AutoCAD. AutoCAD EDC is a host application that is installed on the operating system. AutoCAD EDC allows users to connect to files in AutoCAD, VectorWorks, and other applications that use the AutoCAD drawing format.

AutoCAD LT is built on the same foundation, providing the ability to connect with AutoCAD, VectorWorks and other applications that use the AutoCAD drawing format.


The AutoCAD User Interface is a distinctive feature, which allows interaction with the software via a graphical user interface. The user interface has two main components: the

A panel of catalytic antibodies directed against activated alpha-1 adrenergic receptors.
In this study, a panel of nine catalytic monoclonal antibodies, obtained by immunizing mice with alpha 1-adrenergic receptors (alpha-1AR) coupled to an oligosaccharide analog, was analyzed for their ability to reduce cAMP levels in intact cells. Among the nine antibodies, seven reacted with receptors coupled to the alpha-1AR-specific oligosaccharide, whereas the other two recognized both uncoupled and oligosaccharide-coupled alpha-1AR. These two antibodies, alpha 1C-3 and alpha 1C-4, were also found to possess differential cAMP-reducing activity, alpha 1C-4 being more potent. Moreover, alpha 1C-4 was able to degrade the alpha-1AR extracellular domain by the release of a fragment that resulted in a loss of receptor expression. These data suggest that alpha 1C-4 recognizes a site of internalization of the receptor. Finally, the cAMP-reducing activity of these antibodies was assayed on intact cells and was found to be directly related to the expression of the high-affinity alpha-1AR subtype. This panel of antibodies appears therefore as a valuable tool to study the regulation of expression and function of the alpha-1AR.Fluxor, an online sportsbook, has found itself in hot water for accepting an $11,500 bet in favor of the Golden State Warriors to win the NBA Championship

Release Notes:

Support for DXF files is updated to support the most recent version of Open Design Alliance’s (ODA) standard.

DXF and WMF format support will also be supported in AutoCAD 2023 when Open Design Alliance updates their standard to include support for these file formats.

Large drawing files can be created in a new, streaming format: DXF-Stream. It speeds up the process of creating large drawings by reducing the size of drawing data that must be saved to disk. DXF-Stream files can be delivered over a network, saved to CD, or copied to a local disk. (video: 1:29 min.)

Support for multi-resolution, layered images is available. You can also save the contents of multiple images in a single DXF file, so you can save the contents of multiple layered images to disk at once. (video: 1:49 min.)

Multi-user AutoCAD allows multiple users to use the same application and the same network server at the same time. (video: 1:59 min.)

Toolbars are now available in two-dimensional, layered image views.
