An AutoCAD design drawing.


AutoCAD originated as AutoStyle, a utility created by Autodesk to simplify the process of creating styles. AutoStyle could be integrated into a drawing to create a style, or it could work as a stand-alone application. In December 1982, AutoStyle was released as AutoCAD 1.0 and was an extension of Autodesk’s AutoStyle II graphics utilities which were also marketed by Autodesk.

In the early 1980s, Autodesk contracted with the New Mexico Institute of Mining and Technology (NMIMT) to evaluate software for use in the New Mexico Autodesk Training Center. The evaluation program required students and instructors to input, critique, and rate the software. In addition to reviewing the functional features and ease of learning, the NMIMT evaluation program involved students in using the software. This greatly enhanced the program’s potential market, and the Autodesk training center operated from 1981 to 1985, at which time Autodesk elected to withdraw from the industry-supported program.


On March 30, 1985, Autodesk announced AutoCAD, a desktop design application based on the established Autodesk Style II technology. AutoCAD combined style creation and 2D drafting functions into one application. AutoCAD 1.0 could import and export 3D objects for use in further design processes and was cross-platform, running on IBM PC and Apple Macintosh computers. AutoCAD 1.0 offered more advanced features than the NMIMT-sponsored software.

AutoCAD 2.0 and AutoCAD 2.5 were released in 1987. The 2.5 version included support for 3D objects in the drawings. AutoCAD 2.5 also included support for Microsoft Visual Basic 3.0 which was released in 1986. AutoCAD 2.5 was rereleased in 1997 as AutoCAD 2001. AutoCAD 2001 added new features and made AutoCAD 2.5 obsolete.

AutoCAD has included free updates for some versions. For example, AutoCAD 2008 R2 introduced a new tool for routing, replacing a previous method used in AutoCAD R2009. This new tool was included in AutoCAD 2008 but wasn’t included in the 2009 version of the software. Later, AutoCAD 2013 introduced a new tool for command line programming to simplify scripting.

Autodesk discontinued selling AutoCAD as an upgrade in 2014.

Artwork Inception
Artwork Inception is a platform based on AutoCAD created by Artwork Development Software that was first released for Windows in 1997. The project has been described as “AutoCAD in the cloud”. Artwork Inception is no longer available for download as of August 2018 and was unavailable to purchase until August 2019.

File formats

The native file format of AutoCAD is the drawing exchange format, or DXF. While not always a feature of the software itself, there is often a capability to export the drawing as DXF to another program or format. In AutoCAD, importing from DXF is a non-linear operation because of the complexity of the DXF specification. In addition, DXF has some limitations in comparison to other 3D drawing formats. The specification for DXF was designed to address many problems of CAD file interchange, but DXF files can only contain objects that have a height and width. DXF files cannot contain assemblies and other non-object objects. DXF is not widely accepted as a format for 3D-modeling in general, because of these limitations.

AutoCAD and DXF are binary, line-based formats and it is possible to convert between the two, but not always easy. In contrast, the vector graphics formats of PDF and SVG have good interchange and printing capabilities. PDF and SVG are also capable of representing animation (PDF using path stroke command and SVG using a tag).

Other CAD systems

Other notable CAD systems include the following:

DraftSight is the only 2D-CAD product by the Autodesk family to be commercially available as of 2018, having been first released in 1992.
Enlighten is a project that aims to create open source software that can provide many of the capabilities of AutoCAD and that can be integrated within AutoCAD. The original project was forked to create AutoCAD Render (now based on the original Autodesk’s Render architecture) and Autodesk Vault, and they have since been integrated with OpenSCAD.
OpenSCAD, the open-source cross-platform SCAD is a generic modeling language for freeform surface and solid modeling and drawing, in collaboration with the American Institute of Aeronautics and Astronautics (AIAA).
Plant 3D, released in 2005, was the first 3D plant modeling software designed as a desktop application and was not intended to be connected to the Internet.

Delivery of bioactive substances to the brain is a long-standing problem. The choroid plexus and circumventricular organs are two sources of entry to the brain. Choroid plexus capillaries have fenestrations and hence, may allow drugs to enter directly into brain parenchyma. The circumventricular organs lack fenestrated capillaries and are therefore, inaccessible to substances delivered to the blood directly. However, a number of circumventricular organs contain fenestrated endothelial cells, which are characteristically seen in the external zone of the median eminence, the area between the optic chiasma and hypothalamus. Specific substances can enter this region by passive transfer across the endothelium, and/or by active uptake into the endothelial cells, which are generally non-fenestrated. We propose to examine the transport of molecules into the rat brain through the fenestrated endothelium of the external zone of the median eminence, using FITC-inulin as a tracer. The effects of microdialysis, intracardiac injection, and osmotic pump implants on brain uptake and distribution of FITC-inulin will be determined. Experiments are also planned to investigate the distribution of FITC-inulin and of 3H-D-glucose in areas of the brain without access to the external zone of the median eminence. Autoradiographic studies of the distribution of 3H-D-glucose and 14C-sucrose in sections of the rat brain will be used to correlate the patterns
