How Do I Become a Mechanical Drafter?
Mechanical draftsmen mainly refer to those who use drawing instruments and equipment to draw mechanical technical drawings based on engineering or product design schemes, sketches and technical descriptions. Mechanical draftsmen are roughly divided into four levels: junior, intermediate, senior, and technicians. [1] Job responsibilities of mechanical draftsmen: design of mechanical equipment, including steel structure design, pipeline structure design, and design drawing output; writing related technical documents.
