WHAT IS CAD ( COMPUTER AIDED DESIGN ) ?

Computer-aided design (CAD) is a computer technology that designs a product and documents the design’s process. CAD may facilitate the manufacturing process by transferring detailed diagrams of a product’s materials, processes, tolerances and dimensions with specific conventions for the product in question. It can be used to produce either two-dimensional or three-dimensional diagrams, which can then when rotated to be viewed from any angle, even from the inside looking out. A special printer or plotter is usually required for printing professional design renderings.The concept of designing geometric shapes for objects is very similar to CAD. It is called computer-aided geometric design (CAGD).CAD is also known as computer-aided design and drafting (CADD).

COMPUTER AIDED DESIGN

CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) space.CAD is an important industrial art extensively used in many applications, including automotive and aerospace industries, industrial and architectural , civil design, prosthetics, and many more. CAD use in worldwide. Mostly use cad software name is autocad , microstation and 3d cad is solidworks , catia , nx , pro-e etc. AUTOCAD is a first CAD software in the world.

in the 1980s computer-aided design programs reduced the need of drafts men significantly, especially in small to mid-sized companies. Their affordability and ability to run on personal computers also allowed engineers to do their own drafting and analytic work, eliminating the need for entire departments and the traditional drafting supplies they used. In today’s world, many students in universities do not learn manual drafting techniques because they are not required to do so. The days of hand drawing for final drawings are virtually over. Universities no longer require the use of protractors and compasses to create drawings, instead there are several classes that focus on the use of CAD.

USE OF CAD —-

CAD technology is used in the design of tools and machinery and in the drafting and design of all types of buildings, from small residential types (houses) to the largest commercial and industrial structures (hospitals, hotel , school , collage and factories).

CAD is mainly used for detailed engineering of 3D models or 2D drawings of physical components, but it is also used throughout the engineering process from conceptual design and layout of products, through strength and dynamic analysis of assemblies to definition of manufacturing methods of components. It can also be used to design objects such as jewelry, furniture, appliances, etc. Furthermore, many CAD applications now offer advanced rendering and animation capabilities so engineers can better visualize their product designs.
