The first AutoCAD was named MAYA for “Matching Authoring Tool for Auto-Trim Architecture,” and it was designed to be a low cost alternative to current CAD programs. The name was changed to AutoCAD in 1986. The initial version of AutoCAD contained an internal programming language called DWG. In 1987 the LISP language was added to AutoCAD, providing a graphical programming language that gave users the ability to create and modify drawings in an interactive programming environment. AutoCAD uses a file format called DWG (Design Work Group) which is simply a means to specify objects for the drawing window and the drawing area as well as a method to track drawing updates. In 1992 the first AutoCAD for Windows software was released and in 1994 the first AutoCAD for Macintosh.

At the beginning of development, the software was primarily developed for creating architectural drawings, such as interiors, facades, furniture, and architectural drawings. Autodesk initially built AutoCAD as a low-cost alternative to the high-priced CAD packages of the day. Autodesk has released an array of features into AutoCAD that have made it one of the leading CAD programs on the market today. These features include AutoCAD 2009, AutoCAD 2010, AutoCAD 2011, AutoCAD 2012, AutoCAD 2013, AutoCAD 2014, AutoCAD 2015, AutoCAD 2016, AutoCAD 2017, AutoCAD 2018, AutoCAD 2019, AutoCAD 2020, AutoCAD 2021, and AutoCAD 2022. For home and small business use, users can choose AutoCAD LT or AutoCAD LT Essentials.

History of AutoCAD

A new user was created when drawing commands or commands generated by a previous operation were saved, for example, when drawing, editing, or importing a drawing.

When a drawing was saved or opened, the file-handle was specified in the DWG file by using a null character.

The most important object-dependency was the drawing area, which was in the lower-right corner of the drawing window. If you were to draw in a completely new drawing, the object-dependency was on the drawing window.


The DWG file-handle specified the coordinate origin. When the file-handle was changed, the origin was changed automatically.

The current DWG file-handle is specified in

AutoCAD Crack+

AutoCAD contains functionality for obtaining hardware information such as the model number, serial number, and other hardware-specific information.
AutoCAD comes with a number of utilities, such as the wrench, a utility to manipulate the current object with a set of pre-defined rotations. There is also a utility called “Extensions Manager” which lets user load, unload, and uninstall pre-defined extensions.

In AutoCAD 2012, there are three components to an installation:
AutoCAD: This is the traditional core application for drafting, detailing and mechanical design, as well as 2D and 3D computer-aided design (CAD) and graphics. It is cross-platform, meaning it can be used on Windows, macOS, Linux, and the Apple iOS and Android platforms.
AutoCAD Architecture (ABA): This is a modeling software suite primarily used for architectural and engineering work and incorporates the functionality of AutoCAD and enables the user to create and edit floor plans, 2D and 3D perspectives, models, and other architectural data such as cost estimates and schedules. It also includes rendering and surface modeling functionality.
AutoCAD Electrical (AEC): This is a drawing and specification software suite that includes functionality for design, lighting, drafting, electricity, and industrial drafting. It also includes a database and simulation functionality, and a function-specific command set.

AutoCAD files

AutoCAD files are the native format of AutoCAD. A file is a container for the information a drawing includes. In earlier versions, AutoCAD files were plain ASCII text files. In later versions, they are extended ASCII text files (Extended Markup Language, EML), which include a set of extensions that include animation, line spacing, colors, and many other features. The file type is identified by the extension.dwg.

In earlier versions of AutoCAD, a DWG file is a simple text file that consists of a flat ASCII file with minimal structure. With the release of AutoCAD 2010, the DWG file format was redesigned into an extended ASCII text file (EML). This not only allows for more flexibility in file structure, but also the ability to include animation, line spacing, colors, and many other features. In earlier versions of AutoCAD, the file extension.dwg was not directly attached to the files. In AutoCAD 2008, the file extension.dwg was added.

For older versions of Autocad:
Download the 3.0.1 patch for 3.2 (all versions) and install it.

(Autocad 2010 need the ActiveX version. Do not install it if you have an older version)

Post-installation steps:

Close Autocad.
Check the file c:\autocad_install\ocd.inf, if you have a *.inf file (Windows XP users).
Open the file and search for the keyword “autocad” or “ocd” in the file. If you found a line starting with “autocad”, add a 1 to the end of the line, for example:


If you found a line starting with “ocd”, add a 0 to the end of the line, for example:


That’s all! The game is now activated!

In the following picture is shown a file where the keyword autocad was added to the autocad.inf file (without the modifications from above).

Restart the Autocad application (in my case it was autocad.exe)

Test the game by entering c:\autocad\install\{AutoCAD 2010}
Play the game. Autocad should work fine.

How to un-activate a game

If you decide you do not want to play the game anymore, you must first close the game (exit it by pressing “Esc” on the keyboard).

Then find the file c:\autocad_install\ocd.inf in Notepad and delete the word autocad.

Next find the line starting with “ocd” and add a 0 to the end of the line. For example:


If there is no line starting with “ocd”, go to step 1 again, until you found a line starting with “autocad” in the file.

That’s all! The game is now deactivated.


If you are using Autocad 2010 (which is the default version on WinXP), you need the ACAD_ActClient.dll (found in \autocad\install).

The Autocad 2010 ActiveX control was added with version 3.0.1. If you’re using older versions of Autocad, you need to download this

What’s New in the AutoCAD?

Markup import also now supports external text files and data files.

Markup Assist will automatically correct most common mistakes and help you avoid repetitive errors when drawing.

If you are using the Excel® Integration for AutoCAD, you can now import a new, Excel document, export a previous, Excel document, and work with the contents of a specific range within a document.

Multithread, Rebuild, and AutoClip Printing:

By using the new Multithread and Rebuild command buttons in the drawing area, you can now rebuild your drawings up to 10x faster than before.

You can also use the multithread and rebuild commands to customize your environment and processing speed as much as you like.

Take advantage of AutoClip printing to save even more time on your drawings. When drawing with a clipped object, AutoCAD only prints the portion of your drawing that is visible. AutoClip allows you to print this drawing portion as a whole layer of the AutoCAD drawing.

AutoCAD will automatically print the most recently used layers when printing multiple layers from the same drawing (note: you must be on the same drawing).

You can now draw lines, arcs, and circles, and cut them with the new automatic join command.

Note: these are new features and not available in AutoCAD 2019.

Graphical User Interface Enhancements:

AutoCAD offers a more intuitive and colorful way to use commands and tools and to organize drawings and layers.

You can now see the name of each layer you are working with (note: layers do not have names by default).

Layers and group boxes now display a new tool tip for the tools used to select or manipulate them, as well as other graphical information about them.

You can also have multiple instances of the drawing area in each tab of the ribbon, allowing you to work on different drawings in the same session.

New display features make the drawing area easier to see.

You can now enlarge all drawing objects and the ribbon, so you don’t have to scroll to view the drawing area.

With the new zoom toolbar, you can zoom in and out quickly and easily.

More editing and drawing commands are now easier to see.

You can now sort by name to find your drawings and layers more easily
