The term CAD stands for computer-aided design, which combines the arts, sciences, and commercial practices in the fields of engineering and architecture. Computers are used to store and retrieve data in almost every business. Design projects also utilize computers.

Engineers, architects, and other design professionals use a variety of computer-based technologies called computer-aided design (CAD) to help them with their design work. Using computer-aided design, it is feasible to create digital 2D and 3D models of products before they are ever manufactured. You may swiftly introduce new, distinctive products to the market by using 3D CAD to make designs easier to share, examine, simulate, and update. You can find many institutes that teach CAD courses like CADD Centre, the best CAD Centre in Chennai to learn and enhance your career growth.


Within the Product Lifecycle Management process, it serves as the primary geometry creation tool and occasionally uses specialized hardware. The current packages span from 3D solid and surface modelers to 2D vector-based drafting solutions.

  • Products can be goods utilized by end users or intermediate goods used in other products, and CAD is used to design, develop, and optimize these products.
  • Additionally, CAD is widely used to draw and design all types of buildings, from modest residential types (houses) to the largest commercial and industrial structures. It is also used to create equipment and machines used in the fabrication of components (hospitals and factories).
  • However, it is also used throughout the entire engineering process, from conceptual design and layout of products through strength and dynamic analysis of assemblies to the definition of manufacturing methods for components. CAD is primarily used for the detailed engineering of 3D models and/or 2D drawings of actual physical components.
  • Within the context of computer-aided technologies, CAD has emerged as a particularly significant technology, offering advantages like reduced product development costs and a much-shortened design cycle.
  • With CAD, designers can plan and create their work on a screen, print it out, and save it for later revision, which speeds up the sketching process.

Who utilizes CAD?

A wide range of occupations employs computer-aided design. CAD software is extensively used in numerous projects in the arts, engineering, and architecture fields. Many different occupations use CAD tools, including but not limited to:

  • Architects
  • Engineers
  • City planners
  • Graphic designers
  • Animation illustrators
  • Drafters
  • Fashion designers
  • Interior designers
  • Exterior designers
  • Game designers
  • Product designers

Courses and Eligibility for Admission

A course in computer-aided design (CAD) is often taught for a short time, usually between three and six months. A very good grade in science or technology at the intermediate or secondary level can be beneficial.

Graduates with backgrounds in science and engineering are preferred above those with other backgrounds. Anyone who has an engineering degree, diploma, or ITI certificate in the mechanical, automotive, or electrical branches of engineering is qualified to enroll in a CAD/CAM course.

The qualifications for selection vary amongst institutions. B.Tech., B.E., A.M.I.E., B.Sc. (with mathematics, statistics, computer science, or physics as a required subject), B.C.A., a bachelor’s degree in environmental or disaster management, or a B.A. or B.Sc. (with geography or geology honors) are the requirements for the Jadavpur University center for computer-aided design.

Job Prospects & Career Scope

From engineering craftsperson to engineering technician, there is a clear path for advancement through part-time study for a relevant EDEXCEL/BTEC HNC/D, SQA NC group award qualification, or NVQ/SVQ level 3.

It may be possible to study part-time for these certifications while working as an engineering operative or in a non-engineering position and then apply for a position as an engineering technician.

Professionals with the necessary qualifications can find work in manufacturing facilities, research and development enterprises, and other connected businesses. Given the rise in CAD/CAM training facilities in recent years, one career opportunity that is also available is teaching.

Employment Package

Those who have an engineering degree or diploma will benefit from taking a CAD or CAM course. It is a career that requires sufficient investigation before development.

Only the sky is the limit when it comes to salaries in this sector. Depending on one’s level of industry knowledge, one can make between Rs. 30,000 and Rs. 50,000 every month.

CAD advantages

In comparison to traditional technical drawings and manual drafting, the use of CAD design tools can offer engineers and designers a number of benefits, including:

  • lower production costs for designs;
  • There is no requirement to completely redraw a sketch because changes can be made without affecting other design aspects;
  • superior designs with documentation already included (such as angles, measurements, and presets);
  • designs that are more detailed, exact, and easier to comprehend for collaborators than hand-drawn drawings;
  • Utilizing digital data can facilitate teamwork, and software features can aid in technical procedures like solid modeling and generative design.
