The job of a freelance CAD designer or engineer is to help develop models, blueprints, or technical schematics using computer-aided design software, such as AutoCAD. A CAD designer may work in many fields, including architecture, civil engineering, product design, manufacturing, landscape design, and electronics. Their responsibilities are to create technical drawings or develop prototype draft concepts on behalf of a client. Although this is a contract position, a freelance CAD designer often works with an in-house project manager or specialist who communicates the design needs of the client and ensures the proper technical specifications are included for builders or manufacturers.
