Drafters make drawings and plans to specify dimensions, materials, and processes used in the making of a final product. These drawings are guidelines for the workers who will actually do the building. A draftsperson can also make drawings from blueprints, engineering sketches, photos, and other sources, which show how parts and other objects work, their relation to one another, and how they will be put together.

Drafting work has many specialties, each with its own set of knowledge and skills applying to different fields.

Architectural drafters deal with the structural, functional, and decorative features of structures and buildings. They may specialize in residential, industrial, commercial, or public buildings.

Electrical drafters make wiring diagrams and schematics of electrical circuits for use by those who install and repair electrical systems.

Civil drafters work on plans for major construction projects such as dams, roads, bridges, and sewage systems. They make drawings, and topographic and relief maps, which often cover large areas.
