A CAD (computer-aided design) designer, or drafter, is responsible for generating technical drawings via software that will aid in the building or manufacturing of things. As a CAD designer, you may work with architects or civil engineers to design blueprints for things like buildings or bridges. You may work with manufacturers to create precise technical drawings of items to be produced. You may also visit job sites or factories to see how the project is going and make updates as needed. Overall, you help the concepts of your clients become a reality through your digital images and prints.
