Mechanical designers create designs for machines and mechanical devices. They combine drafting skills with mechanical engineering knowledge to assist product development engineers in the manufacture of new mechanical devices.echanical designers must have expert knowledge of mechanical and electrical engineering, computer drafting programs, and physical construction techniques. A career as a mechanical designer requires an aptitude for drawing.
From all of the engineering disciplines, mechanical engineering is one of the broadest. Mechanical engineers are involved in designing, researching, development, and the testing of mechanical and thermal devices. This includes engines, machines, and tools. Mechanical engineers are characterized by their creative abilities, for developing a breadth of knowledge in their industry, and for being versatile.
