Since its introduction, AutoCAD has become the industry standard for 2D drafting and drawing. As a result, it is the most widely used CAD software. AutoCAD’s functionality is also increasing steadily, with new releases every year, adding support for 2D and 3D drafting, various types of measurement, schematic capture, and new features such as parametric drawing.
AutoCAD was originally released by Aldus Corporation in 1982 as one of the first desktop CAD software programs. It could be used on a variety of microcomputers that ran its internal operating system, including the Macintosh, Atari 800, and Tandy TRS-80 Model II and III computers. It used a custom graphic user interface (GUI) called GraphWriter, and was bundled with a programming interface called Graph. Both GraphWriter and Graph are now available as open-source tools for the Python programming language. The first version of AutoCAD was referred to as simply “GraphCAD”.
On August 17, 1982, AutoCAD version 1.0 was released by Aldus. It was the first version of AutoCAD to feature a GUI and to be distributed on floppy disks. It featured 16-bit color, although it could only handle 256 colors, as the PAL display standard used at the time required 256 separate colors. On September 17, 1982, it was bundled with Aldus’s port of the BASIC programming language for the new Apple II computer. It had a price of $495.
Aldus sold AutoCAD to Premier Industrial Designer’s Software (PIDS) in 1984. Premier was bought by Corel in 1999. Corel then merged with other software company EMC to form The Corel Corporation. In 2004, Corel spun off its personal and business information (PBI) group into a new company called Corel Corporation. Corel’s product was then named CorelDRAW. On November 21, 2012, Corel and AutoDesk announced a merger. The new company, named Corel, continued to sell the original “AutoCAD” trademark. In 2015, Corel announced the release of AutoCAD LT (2015 version). The 2015 version includes the ability to create and edit drawings from an iPad or other iOS device.
Two competitors were introduced after Autodesk acquired Autocad, Autodesk AutoCAD 360 and Autodesk Inventor (now Autodesk Fusion 360). Both are subscription-

Visual LISP is a macro programming language, which is integrated with AutoCAD. Visual LISP was also used for the development of other products such as AutoCAD Architect, AutoCAD Electrical, AutoCAD Civil 3D, and AutoCAD R14. In AutoCAD R13, Visual LISP is also integrated with other programs, not just AutoCAD, for example, Inventor and Dynamo. Visual LISP was also the basis of the commercial PostScript printer emulation program called VPL (Visual Printer LISP) AutoCAD began to use the Visual LISP version of AutoLISP in AutoCAD R12. AutoLISP is a dynamic procedural macro programming language; it was not designed for the writing of “user” macros (what AutoCAD calls “user” macros), but rather to be used in combination with AutoCAD’s programming APIs. The primary function of AutoLISP is to execute AutoCAD macros and functions. AutoCAD’s User Macro Language (UML), the third-party programming language, also supports this macro language.
Visula LISP, was one of the first attempts to introduce a unified programming environment between the macro language of AutoCAD and the programming language of Visual LISP.

AutoCAD Architecture (now Autodesk Architecture 2012)
AutoCAD Architecture, published in 2011, is a 2D architectural planning software for 2D and 3D building design and modeling. It is designed for architects, designers, engineers, planners, and construction managers.
There are several editions of AutoCAD Architecture:
AutoCAD Architecture for 2D Design is a 2D drafting software.
AutoCAD Architecture for 3D Design is a 3D modeling and architectural design software.
AutoCAD Architecture has a

Viral disease presenting as a generalized erythematous rash.
A 19-year-old woman with polyarteritis nodosa, chronic liver disease, and peripheral neuropathy developed a generalized erythematous rash. Light microscopy of skin biopsy specimens showed nonspecific perivascular and periadnexal infiltrate, which was seen with greater frequency in the sections processed for herpes simplex virus (HSV) immunoperoxidase studies. The HSV-encoded antigen was detected in sections with perivascular, periadnexal, and endothelial cell infiltrate. No virus was identified with either immunofluorescent or electron microscopy methods. Indirect immunofluorescent studies of the patient’s serum were negative for HSV and other tested herpes viruses and for hepatitis B surface antigen. Thus, the disseminated erythematous rash was caused by HSV and is probably the first reported case of HSV-induced vasculitis. the image that the Department was using for the preparation of an RFP and within two weeks of that email response, the actual RFP was released. It would appear that the RFP was released before the completion of the source selection process.
