Computer aided design

Computer aided design or CAD was originated as an advanced substitute for drafting. Even though the scope of computer aided design is not just limited in drafting, it can be said that, the roots of CAD are very well entrenched in drafting.

At times, CAD is expanded as computer assisted design. Another variant of CAD is CADD, i.e. “computer aided design and drafting”. Even though the objectives of all the variants of CAD find close proximity with each other, the slight difference in applications brings slight difference in its meaning.

Computer aided design is extensively employed in the design and development phases of a product. The product could be a commodity of an end user. Industrial requirements and applications find endless scope in CAD since it can be deployed in the design and manufacture of their tools, machines, products etc.

Apart from these, drafting and construction of buildings ranging from apartments to factories make the optimal usage of computer aided design. 

Depending on the application and requirements, people in various disciplines, go after different systems of CAD. All the 2D CAD systems have numerous programs that are open sourced. Another system of 3D wire frame is an enhancement of 2D drafting.

But, it greatly demands manual interpretation, since every line has to be inserted manually. Creation of real world entities are supported by 3D dumb solids. According to the requirements and necessities, the user can materialize a 2D or 3D object.

Alternations can be made, if necessary. Different other CAD systems are available such as 3D parametric modeling, Vector works etc to meet specific objectives. 

Physical components used in industries, factories etc can be diagrammatically represented using computer aided design. Two dimensional or three dimensional views of physical components can be represented using CAD. CAD finds great importance in engineering discipline.

Mechanical and civil engineering departments find CAD as an extremely helpful tool in the graphic construction of machineries and devices. Apart from all these, numerous job opportunities are opened for Computer aided design experts.
