Mechanical designers work with engineers using computer design software to create from sketches and even field work, technical drawings for equipment, foundations, and facilities.

A mechanical designer is a professional who specializes in creating detailed designs for mechanical systems and equipment.  They work in various industries, such as manufacturing, aerospace, automotive, and construction, to design and develop mechanical components, machines, and systems.

The role of a mechanical designer involves using computer aided design (CAD) software and other tools to create and revise technical drawings, schematics, and specifications for mechanical equipment and systems.  They work closely with engineers, project managers, and other professionals to ensure that designs meet project requirements and are feasible in terms of budget, safety, and functionality.  Mechanical designers may be responsible for creating designs for a wide range of mechanical systems, including heating, ventilation, and air conditioning (HVAC) systems, piping and plumbing systems, industrial machinery, and vehicle components.  They may also be involved in designing products such as consumer goods, medical devices, and electronics.

To become a mechanical designer, one typically needs a degree or certification in mechanical engineering, drafting, or a related field, as well as experience with CAD software and other design tools.  Strong technical and problem solving skills, as well as an understanding of manufacturing processes and materials, are also important for success in this field.
