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.
Mechanical engineers develop and build mechanical devices for use in industrial processes. Mechanical engineering is one of the broadest engineering disciplines. Mechanical engineers research, design, develop, build, and test mechanical and thermal sensors and devices, including tools, engines, and machines. Duties. Mechanical engineers typically do the following: Analyze problems to see how mechanical and thermal devices might help solve a particular problem
