Drafter

Position Title

Drafter

Alternate Titles

Computer-aided design (CAD) designer and CAD operator

Job Description

Drafters use software to convert the designs of engineers and architects into technical drawings and update technical drawings when changes are made to the system. These technical drawings contain information on how to build the project, the dimensions of the project, and the materials needed in the project. Drafters work across the hydropower sectors, creating technical drawings for electrical and infrastructure manufacturing, installation, and construction of hydropower facilities.

Education and Training Description

Drafters typically attend a drafting program through a community college or technical school after earning their high school diploma. Some drafting programs lead to an associate of applied science in drafting or a related degree, while others lead to a certificate or diploma. 

Drafting programs often include courses in design fundamentals, sketching, and CAD software. Students generally take 2 years of full-time education to earn an associate’s degree. Certificate and diploma programs can vary in length but can usually be completed in less than 2 years of full-time education. To enter the hydropower workforce, students frequently specialize in a particular type of drafting, such as civil, mechanical, or electrical drafting. 

A certification from the American Design Drafting Association is not required, but demonstrates competence and knowledge of nationally recognized practices. Certifications are offered for several specialties, including architectural, civil, and mechanical drafting, and several different experience levels, including apprentice, certified drafter, and certified design drafter.

Job Profile

Drafters use software to convert the designs of engineers and architects into technical drawings and update technical drawings when changes are made to the system. These technical drawings contain information on and specifications on how to build the project as well as the materials needed in the project.

The software systems drafters use to create these technical drawings are often referred to as CAD systems. Drafters work with CAD to create schematics that can be viewed, printed, or programmed directly into building information modeling systems. These systems allow drafters, architects, construction managers, and engineers to create and collaborate on digital models of physical dams, buildings, and machines. Through three-dimensional rendering, building information modeling software allows designers and engineers to see how different elements in their projects work together.

Four common types of drafters in the hydropower field include civil, electrical, electronics, and mechanical drafters. Civil drafters prepare topographical maps used in dam construction. Electrical drafters prepare wiring diagrams that construction workers use to install and repair electrical equipment and wiring in hydropower power plants, electrical distribution systems, and other related systems. Electronics drafters produce wiring diagrams, assembly diagrams for circuit boards, and layout drawings used in manufacturing and in installing and repairing electronic devices and components in hydropower facilities. Mechanical drafters prepare layouts that show the details for a variety of machinery and mechanical tools and devices. These layouts indicate dimensions, fastening methods, and other requirements for assembly.

Drafters typically do the following:

• Design plans for dams, electrical wiring at hydropower facilities, and component manufacturing machinery using CAD software
• Use CAD software to create technical drawings based on rough sketches and specifications created by engineers and architects
• Design products with engineering and manufacturing techniques
• Add details to architectural plans from their knowledge of building techniques
• Specify dimensions, materials, and procedures for new products
• Work under the supervision of engineers or architects.

Job Skills

Materials engineers typically need:

• Creativity. Drafters must be able to turn plans and ideas into technical drawings of dams, buildings, tools, and electrical systems.
• To be detail oriented. Drafters must create designs that are technically accurate according to the provided plans and specifications.
• Interpersonal skills. Drafters work closely with architects, engineers, and other designers to make sure that final designs are accurate. This requires the ability to communicate effectively and work well with others.
• Math skills. Drafters work on technical drawings. They may be required to calculate angles, weights, costs, and other values.
• Technical skills. Drafters in all specialties must be able to use computer software, such as CAD, and work with database tools, such as building information modeling.
• Time-management skills. Drafters often work under tight deadlines, so they must work efficiently to create and update designs within established schedules.
