History of AutoCAD

AutoCAD is a desktop application. It was the first desktop CAD program. Before 1982 the only practical CAD programs were working on mainframe or minicomputers and each CAD operator (user) had to work at separate graphics terminals. By creating CAD on the desktop, AutoCAD enabled all users to work from the same system (cad operator), eliminating the need for the need for CAD operators to work from separate graphics terminals, a benefit to CAD operators as well as CAD designers. Before 1982, most CAD programs ran on mainframe or minicomputers, with each CAD operator (user) working at a separate graphics terminal. These programs were not suitable for the desktop because they required significant memory and CPU resources. AutoCAD is the first desktop application to provide complete 2D and 3D CAD functionality, including 2D drafting, 3D modeling, 2D and 3D drawing, and 2D and 3D printing.

AutoCAD is a commercial desktop computer-aided design (CAD) application, originally developed and marketed by Autodesk and available for the following operating systems:



Mac OS X


AutoCAD is available in both 32- and 64-bit versions. The 64-bit version has been available since AutoCAD 2015. AutoCAD is licensed either by the user or the organization that manages the computer and software.

The standard AutoCAD license is for perpetual use on a single machine.

Programs such as AutoCAD, AutoCAD LT, and Autodesk Inventor are the products of Autodesk, Inc., a company based in San Rafael, California.


AutoCAD is often used for two-dimensional drafting (2D) and three-dimensional (3D) modeling. The 2D data created in AutoCAD is the basis for 3D data, and in turn, the basis for a print or visual representation.

2D: The 2D Drafting feature in AutoCAD supports drafting with a 2D drafting tool, such as a ruler and a straightedge, and importing data from other applications, such as drawing board, measurement, and drawing templates. In addition to using AutoCAD for drafting, engineers can create 2D drawing data using other applications such as CAD and DGN data formats.

DGN is a predecessor to CAD.


In the 1980s, Autodesk introduced 2D drafting and modeling through the TurboPascal and TurboBasic programming environments, based on the National Center for Supercomputing Applications (NCSA) Portage/hp300BSD PDP-11 Unix operating system.

3D modeling on the PowerTalk language began in the early 1980s. The original version was a package of 16 separate programs, stored on magnetic media, that could be installed on a Sun 4 computer. It was introduced with Autodesk Graphics Suite 2.0, and used the Borland Pascal compiler. For several years, the only viable programming language for modeling was Visual LISP.

Work in 2D modeling continued throughout the 1990s, with strong emphasis on 3D modeling. Windows and Graphisoft 3D Studio Max were introduced in 1995. It was later superseded by the now discontinued Macromedia Freehand, which had won a number of awards, including the same category of Autodesk’s Game Design Challenge in 2004. Macromedia Flash was added as an option with the release of Maya in the middle of 2005.

In the early 2000s, Modo became a separate product from Autodesk. It was built on top of the open source Maya software.

Autodesk released Maya in 2001. This was a new platform for 3D modeling. Later in 2001, Autodesk released 3ds Max for CAD 3D modeling software, and also introduced Adobe Flash as a 3D modeling solution. 3ds Max continued to be supported and developed by Autodesk as the centerpiece of their motion graphics and animation studio, and also continued to be a significant software tool for architecture. Flash became a preferred tool for many designers, animators, and creative professionals.

In 2009 Autodesk released Maya 3D, which was based on the 2010 release of Maya and did not contain previous Maya assets.


Autodesk’s first product for computer-aided design was Graphics Suite, which contained utilities for image editing, shape creation, 2D drawing, and the assembly of the latter into 3D models. Drawing was done on a vector graphics display such as a graphics tablet, a mouse, or a laser scanner. The first version of this software was Autodesk Graphics Suite 1.0 for Apple Macintosh, released in 1984.

Autodesk Edit was introduced in 1987, for the introduction of Windows. The

A new approach is described for determining the shape of probe-treated semiconductor surfaces. A simple and relatively inexpensive measurement technique has been developed to investigate the effects of probe-surface interactions on the shapes of probe-treated surfaces. The structure of a probe-treated semiconductor surface is measured at different heights from the substrate to determine the surface profile. Based on the surface profile, the height distribution of the surface can be reconstructed. This methodology can be applied to characterize the profiles of probe-treated semiconductor surfaces, and to determine the shapes of probe-treated semiconductor surfaces, including sub-10 nm semiconductor structures.Q:

What’s New in the?

New drawing tools:

Intuitive shape tools for creating complex components (video: 1:05 min.)

New tool sets for multilevel elements, for example, top surfaces, bases, and structural elements (video: 3:25 min.)

The multilevel elements in drawings can be used to enhance your modeling and design experience (video: 3:55 min.)

The pipe tool is now available for 2D surfaces, as well. (video: 2:30 min.)

The dot tool lets you draw lines on the base of a multilevel element, which simplifies creating complex shapes. (video: 3:05 min.)

Multilevel Cut tool:

With the help of multilevel elements, it’s easy to separate shapes from one another. For example, the person in the video above removes the telephone and other components of the house to give the design more of a modern look.

Axis and AutoCAD Dynamic Materials:

Axis and Dynamic Materials: Autodesk’s new line of axis and axes and Dynamic Materials sets the standard for the future of 3D engineering. Combining the strengths of the powerful AutoCAD program with the rich features of the Axis 3D module, Autodesk’s new axis and axes and Dynamic Materials sets will become the baseline for new and existing users alike.

The axis and axes are an ideal complement to AutoCAD and its dynamic materials, giving you the power to control important aspects of your design. The axis and axis sets, in particular, will make creating strong, stable, reliable structures easier than ever before. Dynamic materials, like those available in Autodesk’s AutoCAD Dynamic Materials sets, will make it easier than ever to control important aspects of your design, such as material properties and specification details.

As we have mentioned in our previous posts, axis are a critical part of every CAD program. You can’t really design without them. And what is the best way to design with Axis and Dynamic Materials? By using the Dynamic Materials function to quickly modify the properties of your models, in real time.

AutoCAD Dynamic Materials will deliver the most dynamic 3D environments, and with them, the most dynamic users. The Dynamic Materials tools are the key to providing effective on-the-fly material property changes that allow you to precisely control material properties during design.
