History
AutoCAD was originally developed for the drafting market as a product of The I.R.I.S. (Institute for Research in Information Science and Systems) as part of a project called SketchPad. The SketchPad project was an effort at the Massachusetts Institute of Technology to develop a system for providing people with a graphical interface to CAD. SketchPad was intended to be a prototyping and modeling tool for interactive electronic drawing and modeling. SketchPad was never released, however, and SketchPad was later renamed CADS and then ultimately AutoCAD. SketchPad was the original name of AutoCAD.
The first version of AutoCAD, released in December 1982, was not compatible with existing drawing files. The first three years of AutoCAD’s development were spent improving the system’s compatibility with existing drawings. In 1983, AutoCAD was named by Computerworld magazine as the best new product of 1983.
AutoCAD originally was developed to run on the then-new Apple II microcomputer platform. As a result, it was the first industry-standard CAD program designed for the Apple II. The first commercial release of AutoCAD was in 1984, running on the Apple II. The Macintosh version was not released until 1985. This was because Apple was unwilling to endorse Autodesk’s technology; at the time, Apple’s relationship with Autodesk was rocky, and they were competing with one another in the computer drafting market.
In 1985, after numerous versions and many delays, AutoCAD was released for IBM PC/MS-DOS and Apple Macintosh. The Macintosh version was not available for purchase, but was freely distributed as a demonstration version of the software. (The Macintosh version was not included in the Macintosh’s first boxed release.)
Although Autodesk intended to have a model of AutoCAD, it was never released as a product and was canceled. Instead, Autodesk decided to launch AutoCAD in the $100 to $200 range, and thus the model was developed as a demonstration.
AutoCAD was first commercially available in 1985, selling for between $350 and $1,000.
In 1987, Autodesk released AutoCAD LT, which sold for as little as $100. This version of AutoCAD was developed to be a lower cost alternative to the original AutoCAD product. The new version was programmed in

Forming blocks and symbols
The basic idea of a block is that of an object with identity. It can be tagged, geometrically designed, assigned a text description, and manipulated in the program. A symbol is used to visualize the relationship of blocks; it is generally a collection of blocks and may have dimensions and other properties attached to it. A block can be selected for inclusion in a group (called a “label”) or in an object.
Creating blocks and symbols
The user has an immediate window in which to create blocks and symbols. A simple command such as “2×4” creates a 2 × 4-inch square. New blocks and symbols may be created by using one of the “New” command (e.g. “New line”) or the “Designer” command.
Block creation
Blocks are usually created by specifying geometric relationships between them. The geometric relationships may be of three types: tangency, interpenetration and overlapping, the former two being forms of block interconnectivity. Other relationships such as face or edge are also possible, though these are more difficult to create. The user may create blocks by command or through the menu or graphical user interface (GUI) commands or the design menu of the application.
Each block is given an ID, a set of options, and a number of properties.
Tangency
Blocks may be created by specifying tangency relationships between them. These are the simplest kind of block relationships, and there are three types of tangency: tangent, perpendicular, and displaced. Tangent refers to a line segment where two surfaces or curves come together. Tangent blocks may be used to create profiles (surfaces of revolution) and frets (surfaces of division) (e.g. in a guitar fretboard), or they may be used to create a multiple profile (e.g. in a guitar fretboard). Tangent blocks are commonly represented by type of a point on one block and a line on another block. However, in AutoCAD it is possible to specify a point and a line or a line and a point, but the other way round is not possible.
Perpendicular
Perpendicular blocks are created by specifying two or more planes. The planes may be either parallel or perpendicular to each other. The user creates perpendicular blocks by specifying two blocks to be parallel to one another.
Interpenetration
Interpenetration occurs when

Speaking on 7 News, Brisbane public relations professional Peter Clarke said the label was on the back of all the uniforms.
“The reason why I’m calling for the removal of this label is that I really believe it should be on the back of the uniform for that reason, and because the term ‘black’ and ‘white’ implies something. We’re not all black and white,” Mr Clarke said.
Mr Clarke said the Australian Human Rights Commission had defined a number of different races and ethnic groups but he said it was important to remember that all citizens of Australia were white.
“I’ve made this as a matter of public record that all Australians are white. No matter what our gender, no matter what our religion, all Australians are white,” he said.

“Any other person can talk about white, but I’d suggest you get a dictionary.
“The Australians don’t come in any other colour.”
Mr Clarke has also written to the PM’s press secretary, Lauren Robinson, asking for the label to be removed because it caused “emotional distress and offence” to those who were offended.
“This is really not the time for the government to be taking pride in the design of our uniform,” Mr Clarke said.
“The battle for marriage equality is being fought on the grounds of love and equality, so I’d suggest that if we’re going to be proud of our uniform we should be proud of everyone and the different races, religions, genders and sexual orientations that make up Australia.”
7 News political editor Andrew Probyn reported that the issue was being looked at.
“The PM’s office and the department of defence have had a look at it and they think it’s a good idea,” he said.
But on the Opposition’s Facebook page, shadow treasurer Joe Ludwig asked if it was really the right thing for a “national sporting institution” to be “dabbling in politics”.
What’s New In?
Flowcharting:
Create and draw freeform, organized graphical diagrams that show how a process should work.
Lines and Polylines:
Draw more precise lines and polygons than you have ever before. Lengthen and shorten, curve and straighten, concurve and bend, construct complex lines, and add fills and strokes.
Symbols:
Generate and use symbols without drawing them. Edit symbol properties directly in the symbol palette. Create dynamic symbols that change over time. (video: 1:35 min.)
Graphical Layout:
Rapidly drag and drop objects to place them on a drawing. Quickly resize and reposition items using a scrollable and resizable drawing viewport. Change the placement of multiple objects at once. (video: 1:55 min.)
In addition, AutoCAD now supports DraftSight, one of our newest CAD/CAE applications. So if you need to send designs to 3D CAD software, or work with AutoCAD for CAD or CAE, the interface between AutoCAD and DraftSight is now even more seamless. This is a free download from the Autodesk Application Network.
AutoCAD and AutoCAD LT:
Changes in AutoCAD and AutoCAD LT
If you are running AutoCAD or AutoCAD LT on Windows 10, you might notice that AutoCAD now has the Windows 10 interface. AutoCAD and AutoCAD LT are built for Windows 10, so there are a lot of new features that you will find in AutoCAD.
The Windows 10 design mode and experience is familiar to users of other Windows versions such as Windows 7. It lets you easily view or edit your drawings. You can add shapes, lines, and text, and then easily save and export your work.
All drawings are now also automatically saved using an online backup service. This lets you automatically back up your drawings to the cloud, even if you are not connected to the Internet. This helps to protect your drawings, even if you lose your Internet connection or your computer fails. AutoCAD and AutoCAD LT are also compatible with all of the latest Windows features, such as Windows Ink.
You can also experience the Windows 10 design experience in AutoCAD. But, if you prefer the classic AutoCAD user interface, you can use either the AutoCAD Classic
