Autodesk, Inc. and subsidiaries are wholly owned by a holding company, The Autodesk Group, Inc. (NASDAQ: ADSK).

History [ edit ]

In 1983, Autodesk was founded by Jeffrey R. Sanders and Ryan R. McDowell. Sanders was at the time an industrial engineer at Intel. McDowell was also an industrial engineer at Intel and the co-founder of Impresis, Inc., an on-line computer-aided design service. Sanders and McDowell are the inventors of “the first commercially available on-line CAD system”. Sanders sold his interest in Autodesk to McDowell and other investors in 1987.

In 1985, Autodesk published AutoCAD, which won the “Software Product of the Year” award from the Association for Computing Machinery (ACM). Autodesk’s first software product was sold to the U.S. government. It was used to design aircraft during the development of the B-1B Lancer. Autodesk first publicly exhibited AutoCAD at the 1986 American Society of Mechanical Engineers (ASME) Summer Design Conference, where it won the Computerworld design award. In 1987, Autodesk filed a US patent on the graphical user interface (GUI) for CAD systems and on “commanding and manipulating features”.

AutoCAD supports Python (formally ActiveState Python) by offering a Python 2.x API, as well as a Python 3.x API. The API is similar to the VBA API, but uses a few different functions.

Python for AutoCAD
Python for AutoCAD is a Python API that exposes AutoCAD function to a Python application. Python for AutoCAD is most useful in applications requiring control of AutoCAD functionality at a scripting level.

AutoCAD also supports Perl. The current version of AutoCAD supports Perl 5, which was first released in 1997. AutoCAD modules were developed by Visual LISP script writers who also wrote AutoCAD LISP routines to write the script code and integrate it with AutoCAD.

UDL (User-Defined Language) is an extension for AutoCAD and similar programs. It is a programming language that can be used by programers to add their own special commands to existing programs. UDL can also be used to add custom object definitions and to add new 3D modeling and animation capabilities to AutoCAD. A simple example of a UDL program would be:

Global AutoCAD object “myline” with Properties “Color” “Flamingo” and “Width” “3”.

Line myline from point 1 to 2 with “myline”.


The output should look like this:

This example was created by Nicklas N. Petterson.

The original AutoCAD supported UDL – FLT. This is a language for the 3D scripting of AutoCAD. It is a separate development project that has different goals than UDL. It is a script language that is developed by Oliver Hannemann and is freely available to the AutoCAD community.

The first version of UDL-FLT was released in September 2005. UDL-FLT was then taken over by the team of Hans Bernd Martin and Gilles van den Bosch and has been supported and developed by Hans Bernd Martin and Gilles van den Bosch. They created a UDL that is similar to the syntax used in Visual LISP and Visual Basic. UDL-FLT currently has 50 commands and supports user created libraries. One of the main goals of UDL-FLT was to make the use of the scripting language easier

Nontargeted metabolic profiling of Leucaena edulis L. seed tissue in response to drought stress.
An untargeted metabolomics approach was used to evaluate the effect of drought stress on the seed tissue of Leucaena edulis (LC), a drought-sensitive legume species. When compared to control plants, drought-stressed plants showed a significant increase in the concentration of several free amino acids (pISLAMABAD: The State Minister for Water Resources Rehan Mehsud has confirmed that Prime Minister Imran Khan has given permission to the Army to fly its helicopters on the gas fields located in Khyber Pakhtunkhwa’s North Waziristan tribal region.

Markup Assist enables you to add content to a design by importing instructions from a clip art or other image file, then using them to easily label, sketch, or annotate your drawings. (video: 10:10 min.)

Include 3D models in your drawings by using a special Insert command that creates a family of meshes from the imported geometry. 3D models can be imported from CAD or scanned drawings and meshes added to your 2D design. (video: 3:10 min.)

Create color-coded assembly drawings by associating text or objects in your design with a specific color or color range. (video: 2:40 min.)

Organize and streamline your files with native CAD features, such as smart tags, section break lines, paper space, and toolbars. (video: 4:15 min.)

Share and collaborate on designs by creating new drawings with an unlimited number of users. Users can easily add revisions, annotations, and notes to a drawing, as well as work on the same drawing simultaneously. (video: 2:02 min.)

Keep design concepts organized with automatic CAD task bars and customizable toolbars. (video: 2:15 min.)
