AutoCAD LT was introduced as a version of AutoCAD specifically designed for educational use, including schools. The commercial licensing cost for AutoCAD LT is US$3995. All users of AutoCAD LT are required to pay a yearly license renewal fee and to obtain access to the Autodesk Education Network (AEN).

AutoCAD is licensed by Autodesk on a perpetual basis. It is a multi-user platform with shared databases. The software was developed to be compatible with Windows 95 and above and Microsoft SQL Server. AutoCAD 2013 was released in June 2013, AutoCAD 2014 in June 2014, and AutoCAD LT 2015 in June 2015. AutoCAD 2017 was released in June 2016. The AutoCAD LT 2017 version is the first release of the product since its version was built upon the Autodesk 2018 Core. AutoCAD 2017 is functionally similar to 2016 except for its improved performance and capability, better rendering and features, and the addition of DWG documents.

AutoCAD is available as a single-user, multi-user, and team-collaboration product.



AutoCAD was first developed by John Walker. AutoCAD was initially released as a single-user software package. At first, the only way for users to share files was through the Dbase system, which is a proprietary system owned by Walker’s employer. Soon after the initial release of the software, Walker began working on a multi-user version of AutoCAD.

In 1983, AEC Tech, a company that developed non-linear plotting software, created the ACM suite, including AutoCAD. This was the first time that non-linear software was delivered to the market. Since this point in time, the non-linear market has become dominant as users want to view a model from different angles.

In 1985, Autodesk acquired AEC Tech, renamed the company Autodesk and introduced AutoCAD as a single-user software package. A multi-user version was not offered at this point in time. The company’s focus was on the non-linear market, not on the CAD market. In 1995, Autodesk purchased Engineering Associates and added this company to the Autodesk portfolio. Engineering Associates developed the popular AutoCAD Map Editor and Autodesk Mapper products, which are now owned by Autodesk.

Programming languages

The most common programming languages for creating customizations or macros for AutoCAD Crack Mac are Visual LISP and AutoLISP. They allow writing C++ and AutoCAD-specific code to be executed by AutoCAD. They are similar to Lisp dialects and allow for syntax highlighting, which is a feature of text editors. In AutoLISP, as in Lisp, a program is written in one or more function blocks. Other languages with similar functionality include C++Builder and ObjectARX. In the latest versions of AutoLISP and Visual LISP, similar functionality is available through the VBA and Visual Studio scripting language, respectively.

Customization and automation

CAD customization
CAD customizations allow a user to add or modify elements of the program. Because CAD programs have a large number of parameters to edit, they are often used to create scripts.

The customization of a CAD program can be created in a number of ways, including programming languages, user interface and creating scripts.

Software is commonly written in a scripting language, such as BASIC, AutoLISP, JavaScript or VBA, which contains the definition of a program. The customizations or macros can be either standalone programs, which can be directly run from the program or stored as a part of the CAD program. The term CAD scripts is sometimes used to refer to either standalone programs or part of the CAD program which are designed to be run as part of the program. Because CAD programs are often large and complex, the customization of the program can be automated.

There are three ways to create a customization or macro script:
Programming languages, which include AutoLISP, Visual LISP, VBA, and ObjectARX, which can be used to create standalone programs or to add customizations to the program.
User interface, which allows a user to create a customization or macro script by creating a series of dialogs, which run automatically when the user clicks OK on a predefined sequence of dialogs.
Scripting the customizations, which is the fastest and easiest way to create a script.

Although the first two ways of creating a customization script are widely used, the third way has advantages as well. The design of a user interface often requires programming skills and is not easily understandable for a layman. By creating a macro script, a non-programmer can create a customized program. The only limits on what can be done
