AutoCAD does not use object-oriented programming (OOP) or structured programming. Instead, it uses a procedural programming approach that dates back to the early 1970s.

The origin of AutoCAD

AutoCAD evolved from the Autocad Civil Systems (ACS) project, which was funded by the U.S. Department of Defense. The goal was to develop a Computer-Aided Drafting (CAD) software package for the AutoCAD graphics system, which was a VAX-11/780 mainframe computer at the Massachusetts Institute of Technology (MIT).

The project was led by principal engineer Chuck Whitacre, who was an early proponent of graphical displays and CAD software on mainframe computers. While the original AutoCAD software package did not have a graphical user interface, a modified version with a GUI was released in 1984.

The basis of AutoCAD’s graphics system was the Autodesk Graphic Tools System, which used two separate display windows: an AutoCAD drawing window and a Graphic Tools window. The Graphics Tools window displayed a 2D vector grid to represent the 2D model of the drawing. The Vector window was a two-dimensional (2D) text editor. Graphics Tools included a small graphics editor, which provided a basic raster graphics editor and an unlimited number of clip paths for drawing dotted lines and dashed lines. The user could also draw ellipses and Bézier curves, and move and rotate objects using simple drag and drop commands.

The original AutoCAD was sold for $35,000 (in 1990s dollars). The first licenses for the software cost $150. The first AutoCAD users were from the MIT Laboratory for Computer Science. It took a year for users to determine that the program could be used for more than just drafting. The program was so successful that it eventually changed the direction of its development.

The AutoCAD 2.0 and 3.0 releases incorporated support for the object-oriented programming language ObjectARX.

History of AutoCAD

AutoCAD 2.0 was released in January 1987. The program cost $7,500 and was available for the IBM PC, IBM PC/AT, Apple II, and the Macintosh platforms. The Apple II version did not have a drawing window.

AutoCAD 2.1, released in December 1988, added support for the Apple Mac. The user could draw on a drawing canvas and define the object

Temporary occlusion of the renal vein is a unique approach in the treatment of renal stones. This meta-analysis is performed to evaluate the effectiveness of temporary occlusion of the renal vein in the treatment of renal stones. A comprehensive search was conducted to identify randomized controlled trials comparing temporary occlusion of the renal vein with renal artery embolization or open renal surgery in the treatment of renal stones. The outcomes evaluated included the reduction of blood loss, the operative time, the number of shock waves, the mean hospital stay,

Dr. Lim’s insight:

Approximately, 40% of the world’s population suffers from some form of dental issue. The sheer number of people suffering in this way is reason enough to look at ways to care for these individuals with simple treatments that are both cost effective and painless.

There are a number of dental treatments that can be offered in addition to basic dentistry procedures such as teeth cleaning and fillings that can be made relatively pain free. One of the first to be used is dental implants, the name for tooth replacement implants.

These implants, if a person is to have them placed in the jawbone, can be left to grow over a period of several months in the jawbone of the individual. Once this process has been completed, a dental crown, made of a tooth-like material, can then be placed over the implants. The crown is used to act as a temporary replacement for the teeth that are absent and is made to fit closely to the implant, acting as a natural feel and appearance for the teeth.

Other treatments, such as dental veneers and dental bonding can be offered to improve the appearance of teeth and also to correct dental flaws. Both of these treatments can be used to create a healthier look for the individual.
