    Computer-aided design (CAD) is the use of a wide range of computer-based tools that assist engineers, architects and other design professionals in their design activities. It is the main geometry authoring tool within the Product Lifecycle Management process and involves both software and sometimes special-purpose hardware. Current packages range from 2D vector based drafting systems to 3D solid and surface modellers.

    CAD is sometimes translated as "computer-assisted", "computer-aided drafting", or a similar phrase. Related acronyms are CADD, which stands for "computer-aided design and drafting", CAID for Computer-aided Industrial Design and CAAD, for "computer-aided architectural design". All these terms are essentially synonymous, but there are some subtle differences in meaning and application.

    CAD has become an especially important technology with benefits, such as lower product development costs and a greatly shortened design cycle, because CAD enables designers to lay out and develop their work on screen, print it out and save it for future editing, saving a lot of time on their drawings.

    History:

    Designers have long used computers for their calculations. Initial developments were carried out in the 1960s within the aircraft and automotive industries in the area of 3D surface construction and NC programming, most of it independent of one another and often not publicly published until much later. Some of the mathematical description work on curves was developed in the early 1940s by Isaac Jacob Schoenberg, Apalatequi (Douglas Aircraft) and Roy Liming (North American Aircraft), however probably the most important work on polynomial curves and sculptured surface was done by Pierre Bezier (Renault), Paul de Casteljau (Citroen), Steven Anson Coons (MIT, Ford), James Ferguson (Boeing), Carl de Boor (GM), Birkhoff (GM) and Garabedian (GM) in the 1960s and W. Gordon (GM) and R. Riesenfeld in the 1970s.

    As a mechanical engineer with 15 years experience using 3D CAD systems (SDRC, Pro/E and SolidWorks) I'm astonished that anyone is offering a BSc in CAD, unless the course was educating you to create CAD systems from scratch, which they do not. CAD modelling is simply not that difficult to master, it's just a tool, an ancillary skill that engineers use to develop and communicate their designs. The analysis applications can get quite a bit more involved but you've got to thoroughly know the underlying engineering principles first. As someone has previously stated, study a mechanical engineering or related course to learn the core skills the market is actually looking for. On these courses you will be exposed to CAD and will learn the basic principles of the technology. Once you get your first job they will most likely send you on a week-long course to learn the operation of their particular CAD system and then you'll develop your skills with the support of your new colleagues and a few additional short courses. That's what happens everywhere I've worked.

    CAD programs are used by many engineers for anything ranging form houses to bombs. they use simple drawing tools set in environments allowing the user to manipulate the lines and draw the models. the united states navy uses CAD programs to make many different things, architects use CAD to draw floor plans and footings for new buildings. the most used CAD program is Auto-CAD by autodesk, at least most widely used in the US.
