Introduction to AutoCAD

AutoCAD is a computer-aided design (CAD) and drafting software application. Developed and marketed by Autodesk, AutoCAD was first 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. AutoCAD is also available as mobile and web apps.

AutoCAD is designed to enable the drafting or creation of 2D or 3D drawings. 2D drawings are for planar objects such as drawings of a house and its rooms, or a blueprint of a car’s body. 3D drawings are for nonplanar objects like houses, cars and bridges. AutoCAD also can combine 2D and 3D drawings into a single project. AutoCAD users can enter drawings or models created with other software applications, such as using a digital camera or scanner to create digital 2D or 3D images. Users can draw, view, edit, print, and publish drawings directly from within the software.

AutoCAD can import or link files from external sources, such as CAD and GIS data. AutoCAD can import other software-generated files, such as 3D images or sound files, into its file structure. This makes it possible to combine 2D and 3D drawing components in a single project.

Today, AutoCAD is available for desktop computer operating systems such as Microsoft Windows and Apple macOS, as well as for mobile operating systems such as iOS and Android. The software is also available on the web. AutoCAD also can be used for project management, which allows an organization to plan, manage, and control projects that require many levels of coordination.

What is a CAD application?

A CAD application is a software application that allows the drawing of 2D and 3D objects, to make them easier to visualize, to share with others, and to perform automatic tasks, such as printing. These objects can be structural, such as buildings, bridges, machinery, and automobiles, or they can be non-structural, such as animals, fruit, or paintings.

AutoCAD is just one type of CAD software available today. Other applications may be better suited for specific needs. Other CAD applications include digital modeling software and

Use of AutoCAD has been used for creating 3D models for the simulation of earthquakes, with results published in a paper in the Journal of Structural Engineering.


Despite its name and appearance, “AutoCAD” is not a word. There are about a dozen words with meanings close to “AutoCAD”.

Although AutoCAD is a CAD software, it is neither the only CAD software nor the best. Some CAD applications, especially those of major manufacturers, are much better than AutoCAD, and AutoCAD is relatively expensive. Other CAD software can operate at far lower cost, and are often completely free.

In the past, CAD software was very expensive and necessary only for certain industries (e.g. manufacturing). The shift to CAD software being accessible to both individual and business users has led to a decline in demand, as the average user does not require full-featured CAD software.


The first example of a CAD application was released in 1968 by Robert M. Faludi, a draftsman who created what would be the first CAD product in the 1970s. He coined the term CAD, which stood for “computer aided design”. The first computer supported by COBOL, the language used by the military and the largest network of computers, was used to develop the first CAD software.

The late 1960s and early 1970s also saw the emergence of the first wave of CAD software for the office market, such as the Bravo family from FACOM, the ST-13 family from Vectorworks, the Sigma series from Genoa, the Hopper series from Silversurf, the Verics series from Autodesk, and Starcad. The latter was developed by VectorWorks and was the first product to use a parametric design approach in CAD.

In the mid-1970s, as CAD emerged from the defense and aerospace sector, in the words of George H. Marquess, “the development of the product became much more an exercise in design and technology than it was a requirement to analyze manufacturing processes or design products”.

The AutoCAD product is named for its use of “Auto” (for “automated”) and “CAD” (for “Computer Aided Design”). In CAD terminology, AutoCAD is a 2D drafting system and related applications. In the same

Generate a 4 digit serial number in the form of aa123456

Click file -> save to and choose a file name then save the file.

Then you have your serial code stored in Autocad.


Adding line between boxes in a matrix

I have a matrix
\matrix (m)[matrix of math nodes,
left delimiter={[},
right delimiter={]},
nodes={inner xsep=5pt, outer xsep=2pt,
inner ysep=3pt, outer ysep=1pt}]
A & B \\
C & D \\

Now I want to have a line separating the boxes. For example A & B | C & D.
How can I achieve this in LaTeX?


With the matrices library
\matrix (m)
A & B
C & D

Otherwise with the booktabs package, if the vertical lines are not needed
A & B
C & D

Asperger’s syndrome (AS) is a heterogeneous disorder with significant cognitive deficits and ASD features. It is characterized by social impairments, rigidity and stereotypies, and

What’s New In?

Your custom objects now stay with you, even after undoing edits. This can help you work through design changes, or implement them as you refine your design. (video: 1:40 min.)

Incremental ordering in the Autodesk Assistant. The new Multiplication and Alignment features help you to avoid collisions during placement operations. (video: 3:37 min.)

Create or modify design elements that are attached to a non-drawing entity such as a path, shape, or text box. Design elements that you attach to non-drawing entities become part of the drawing’s definition, which simplifies your work and makes working with multiple drawings easier. (video: 1:36 min.)

Virtual element snapping, the ability to show the effect of different snapping options in the Drafting Views. You can see how element snaps work in various views by selecting the Snap to option on the virtual element menu. (video: 1:19 min.)

Support for new feature in the Autodesk Assistant. The new Topological Repair tool helps you detect and repair complex topology in your drawings. (video: 2:17 min.)
