Computer-aided design (CAD) is a process that allows computer users to design a variety of products and geometric shapes on-screen, rather than building them by hand. Using CAD software, one can create and modify an object to determine how it will appear and function after it is built. CAD drawings often include a computer-generated image of the design, as well as its dimensions, processes, and materials. CAD drawings may be either two dimensional (2D) or three-dimensional (3D). When an object is drawn in 3D using CAD, the process is often referred to as rendering or modeling, while 2D design is often called “drafting.”
What Is CAD
Computer Aided Design (CAD) is a form of design in which people work with computers to create ideas, models, and prototypes. CAD was originally developed to assist people with technical drawing and drafting, but it has expanded to include numerous other potential uses. A variety of software products designed for CAD can be found on the market, with many being targeted to a specific application or industry.
AutoCAD was one of the first Computer Aided Design programs to be made available on personal computers. It is built to help people design buildings, products, or public spaces, without having to draw up plans by hand. It was released in 1982 by Autodesk, Inc., and offered a personal solution to software that was before then released only for larger workstations. While CAD programs prior to AutoCAD required massive amounts of computing power in the form of gigantic computers, AutoCAD streamlined its operating and optimized it for the IBM PC, allowing people to work from home or on their own work computers.
As a CAD specialist you need to develop standard mechanical engineering drawings such that it can be easily interpreted by the mechanical engineer. Before you start working on mechanical drawings, you must know how to use common mechanical symbols correctly. You have to take special care while relating various mechanical components design drawings to the overall plan of the assembly.

Fluid Mechanics is that section of applied mechanics, concerned with the statics and dynamics of liquids and gases.
A knowledge of fluid mechanics is essential for the Mechanical engineer, because the majority of Mechanical processing operations are conducted either partially or totally in the fluid phase.
The handling of liquids is much simpler, much cheaper, and much less troublesome than handling solids.
Mechanical engineering is the mother of all engineering disciplines. Mass, motion, force, energy, design, and manufacturing – these comprises the world of mechanical engineering. It encompasses the research, design, development, construction and testing of tools, machines and other mechanical equipment. Education from a proper well recognized university, college or school of engineering is vital for all the mechanical engineers due to the highly technical nature of mechanical engineering. According to the ranking of mechanical engineering universities, the top 10 best universities or colleges for mechanical engineering are MIT, Stanford university, UC Berkeley, University of Cambridge, California Institute of Technology (Caltech), Imperial College London, University of Tokyo, ETH Zurich (Swiss Federal Institute of Technology), University of Oxford and National University of Singapore (NUS).

Mechanical engineers design and develop everything you think of as a machine – from supersonic fighter jets to bicycles to toasters. And they influence the design of other products as well – shoes, light bulbs and even doors. Many mechanical engineers specialize in areas such as manufacturing, robotics, automotive/transportation and air conditioning. Others cross over into other disciplines, working on everything from artificial organs to the expanding field of nanotechnology.
Mechatronics is a word originated in Japan in 1980s to denote the combination of technologies which go together to produce industrial robots.
A formal definition of Mechatronics is “the synergistic integration of Mechanics and Mechanical Engineering, Electronics, Computer technology, and IT to produce or enhance products and systems.’’
