Mechanical engineers design, analyse and help manufacture mechanical tools, engines, and machines. They are employed in almost all manufacturing sectors including Heavy machineries, ship building, aerospace, automobile. They are also employed in engineering services and product design companies. They, carry out a wide range of design and analysis activities, in the product development life cycle. Their key tasks include: Concept Sketching, 2D Design & Drafting, 3D Modeling, Prototyping, and Performance & Safety Analysis. Role in the Industry Mechanical engineers who have CAD skills are employed in manufacturing industries including automobiles, aeronautical, engineering, heavy industries, locomotives, and marine. Learning CAD software is important because almost all of these jobs (and more) are performed with sophisticated CAD software that guarantees speed, accuracy, and reuse of work. With CAD skills, mechanical engineers can find employment and increase productivity.
