CAD, an acronym for computer-aided design, is a system combining software and hardware components that enable engineers to design everything from small electrical equipments to huge airplanes. It has drastically outshine the conventional methods of designing and preparing layouts. This technique is also useful for architects as it helps them in the construction of dams, bridges and roads. CAD services India offers drafting services of patent drawings, roof diagrams, mobile tower drafting, 3D models, aerial street mapping, retail store planning and fire evacuation plans. This systematic technique assists in the creation, modification, analysis, or optimization of a design, which further helps in increasing the productivity of the designer. In addition to this, it creates a database for manufacturing, and also improves the quality of a design.

In India, the growth of CAD services outsourcing industry has been astounding. As the worldwide markets are becoming knowledge intensive, the country has emerged as one of the most preferred destinations for such services. Until the late 20th century, when CAD systems were specially manufactured computers, it was bit difficult to use them. But with the coming of CAD software, which runs on any personal computer or workstation, the technology has become user friendly. Days of manual drafting are virtually over, and organisations have consequently eliminated the need of a big team to make a design. Instead, a single person can do CAD drafting thus, making this system affordable to small and mid-sized companies. Computer-aided design, in today's world has become an important technological way, which benefits businessmen with a small budget and less designing time. It enables engineers to prepare a layout on the screen and print it out for use. As the design is saved in the system, it can be edited in the future, thus saving time.

National Association of Software and Services Companies (NASSCOM), a trade association of Indian IT, BPO and KPO industries, reported that the Indian CAD services has a huge global market. These days customers not only look for cost-effective solutions but for efficiency and good customer service. India, with a large population of skilled people, would always be preferred for both back-end and front-end outsourcing. CAD service is a difficult task that needs expertise along with good resources and a dedicated team. Throughout the engineering process, from conceptual designing to product layout, it makes the whole task of the team easier.

The CAD system requires a graphic monitor, mouse, digitizing tablet or light pen for drawing and a high-quality printer for printing design specifications. It helps in making detailed engineered 3D models, which allows engineers to view a design from various angles, to zoom in or out for close ups. Besides, the computer system keeps a track of design dependencies so that when one value is changed, all other values automatically changes. This service assists in every field of engineering and has left a remarkable impact. Furthermore, various CAD applications offer animation capabilities so that engineers can better visualise their product designs.
