AutoCAD is the creation of Dana M. Kurtz, who was an architectural draftsman at Autodesk in 1982. He started development of AutoCAD in 1982, after he had observed problems with pre-1982 architectural CAD programs. He realized that no CAD software existed at the time to enable him to quickly design complex parts. “My first CAD program,” he recalled, “was a crude attempt at [a] general-purpose CAD program. I was a bit anxious, not knowing how this ‘new’ program would be received, especially when I told our clients that the next architectural CAD program would have to be written from scratch in assembly language.”
AutoCAD version 1.0 was first released in December 1982. It became the first major version of AutoCAD to be commercialized and was widely available in 1983. At that time, Kurtz was still in graduate school at the University of Washington in Seattle, but he had about 20 years of drafting experience. His first published work was “AutoCAD: An Architectural Drafting Program,” a paper he published in 1983, although the software did not yet exist.
In 1983, Kurtz formed the company Autodesk, Inc. to commercialize AutoCAD, and the company was incorporated in July 1983. Autodesk’s first customers were architects, engineers and mechanical and chemical design engineers.
AutoCAD remained relatively inexpensive, and in 1985 the price was US$1,999 (US$3,989 in 2012). It was one of the first real-time applications that people could use to create content in the real world. At the time, “real-time” referred to the ability to interact with a computer in real time, or very close to real time, while doing something else. Autodesk had created a time-sharing system to provide real-time interaction for AutoCAD, and Kurtz was interested in building a CAD program with real-time capability.
Autodesk acquired a PC-based CAD system called CadQuad from Hammurabi in 1985 and sold it to AUTOCAD, Inc. in 1987. A year later the new company, which later changed its name to “Autodesk, Inc.”, debuted AutoCAD version 2.0.
AutoCAD 2.0 introduced “Autodesk-style” geometry and features such as AutoFillet, AutoMirror, AutoScale, and AutoFitter. It was the
Multifunction printing is supported via its print server interface, via the Printer class and more directly from the X11 program.
AutoCAD LT — Release 1.0 was released on 3 December 1996, at the same time as AutoCAD — Release 1.1. It was originally only available as a resident client, capable of running from CD, but was later also available on floppy disk or by downloading over a modem. AutoCAD — Release 2.0 (AutoCAD 2002) was released on 9 May 2001, with new enhancements, notably integration with Windows XP and new features including displacement editing.
AutoCAD LT — Release 3.0 (AutoCAD — Release 3.0) was released on 2 December 2004, and included improved scalability and the inclusion of model-space layers.
AutoCAD LT — Release 4.0 (AutoCAD — Release 4.0) was released on 21 September 2006, with enhanced rendering, image importing, drawing of 2D drawings, along with a number of new features, such as the ability to copy and paste lines and compound curves. In 2007, AutoCAD was purchased by Autodesk.
AutoCAD LT — Release 5.0 (AutoCAD — Release 5.0) was released on 28 January 2009.

C++ – An exercise to insert a string to a vector
The exercise is to write a function that inserts a string to a vector. This code is not complete yet but it shows what I mean. This is my vector:
string CPlans::insertWord(string word, vector plan, int id, string2)
if(word.length() > 2 && word.length() plan)
// don’t clear the plan vector
