WHAT IS CAD?
Computer-Aided Design (CAD) is one of the many tools used by engineers and designers in many ways depending on the profession of the user and the type of software in question. There are several different types of CADs. Each of these different types of CAD systems require the operator to think differently about how he or she will use them and he or she must design their virtual components in a different manner for each.
CAD is the use of computer technology for the design of objects, real or virtual.
CAD often involves more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD often must convey symbolic information, such as materials, processes, dimensions and tolerances according to application-specific conventions.
CAD may be used to design curves and figures in two-dimensional ("2D") space or curves, surfaces and solids in three-dimensional ("3D") objects.
CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, aerospace industries, industrial and architectural design, prosthetics and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals. The modern ubiquity and power of computers means that even perfume bottles and shampoo dispensers are designed using techniques unheard of by manufacturers of the 1960s. Because of its enormous economic importance, CAD has been a major driving force for research in computational geometry, computer graphics (both hardware and software) and discrete differential geometry.

Computer graphics are graphics created using computers and, more generally, the representation and manipulation of image data by a computer. The development of computer graphics, simply referred to as CG, has made computers easier to interact with and better for understanding and interpreting many types of data. Developments in computer graphics have had a profound impact on many types of media and have revolutionized the animation and video game industry, jewelry industry and many other industries.
Solid modeling (or modeling) is a technique for representing solid objects suitable for computer processing, such as rings, pendants, bracelets, earrings, necklaces and many other design products.
3D Computer Graphics
3D computer graphics (in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.
Wire Frame Model
A wire frame model is a visual presentation of a three-dimensional or physical object used in 3D computer graphics. It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet or by connecting an object's constituent vertices using straight lines or curves. The object is projected onto the computer screen by drawing lines at the location of each edge.
