Elucidation of Computer Aided Design

Computer Aided Design is assistance of computer in engineering processes such as creation,modifications & optimization,analysis.

Computer Aided Design involves creating computer models defined by geometrical parameters which can be readily altered by changing relevant parameters. CAD systems enable designers to view objects under a wide variety of representations and to test these objects by simulating real-world conditions.

It is an integration of Mechanical and Computer technology to aid in the design process like Drafting, Die Design, Tool Design, Sheet metal,Modeling, Assembly,  analysis of products.

It is both a visual and fast process which is used by Engineers in the Mechanical, Automobile, Production, Plastic, Aeronautics field to design and develop the entire product on the computer before realy producing it.

CAD is mainly used for detailed engineering of 3D models and 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.

The designed product on the computer can be tested, modified and finalize for real production.
