A mechanical drafter creates detailed schematics that show how to put together a machine or how to operate a mechanical system. To create easy-to-follow blueprints and instruction manuals, he or she employs hand drawing skills as well as computer-aided drafting (CAD) software. Drafters can make critical safety and efficiency improvements to designs working closely with engineers and machine operators.
Large manufacturing plants and parent corporations that produce industrial equipment employ the majority of mechanical drafters. They help with the design of large, complex systems such as airplane engines, assembly line stations, robotic equipment, and power generators. Some drafters work for consulting firms that specialize in creating blueprints for equipment made a variety of manufacturers. Furthermore, many experienced mechanical drafters choose to work as freelancers for a variety of clients. Self-employed professionals usually have a lot of flexibility in terms of what projects they work on and where they work.
A mechanical drafter must be very familiar with the types of machinery that he or she is asked to draw, regardless of the specific job setting. To accurately break down the assembly process, a drafter who creates schematics for car engines, for example, must understand how electrical and mechanical components interact in finalized engines. Before beginning work on a new blueprint, he or she usually researches similar plans in depth. To determine if designs will work in practice, the drafter may need to examine parts and take measurements personally.
The mechanical drafter can sketch blueprints and input data into CAD programs if they have a thorough understanding of the machinery. As technology advances, CAD software is rapidly replacing hand drafts, as it allows for easier adjustments, automatic measurement calculations, and the simulation of real-world conditions. A drafter typically creates several drawings for each step in an assembly process, showing pieces in various degrees of detail and from various angles, using either medium. Engineers and technical editors assist the drafter in completing and submitting plans for publication.
The requirements to become a mechanical drafter vary, but most aspirants enroll in vocational school or university programs to gain experience. A drafting and design degree program provides classroom instruction as well as hands-on training in the tools and techniques needed to succeed in the field. Many schools also provide career placement services to assist recent graduates in finding entry-level positions. An individual can put together a comprehensive resume and portfolio that demonstrates his or her abilities with the right training.
In general, breaking into the field of freelance or contract mechanical drafting right after graduation is difficult. Most professionals begin their careers in corporations or consulting firms, either part-time or full-time. A mechanical drafter can begin looking for contract work after gaining experience, success, and strong networking skills.
