Cad Explanation

Computer-Aided Design and Drafting ELC.1Q Before computer-aided drafting (CAD), there were typically three basic levels in an engineering department – they were: engineer, designer, and drafter. The engineer is typically someone with a university degree whose job it is to take input and requests from a marketing department to set the parameters for a machine to be created. The engineer would establish the specifications: how big, how fast, how powerful, how durable, etc. He/she would give this information to a designer. The designer would usually create sketches, or formal layouts, that determined the exact shape and size of all components of the machine. One of the other phases of the process is to determine exactly what material (size, thickness, etc.) would be necessary to support the machine. This might be done either by the designer or by the engineer. The final process would be to take the designer’s information and turn it into formalized drawings that met the standards of the company and the manufacturing department - this final process is be done by the drafter. The drafter was usually the middleman between engineers/designers and manufacturing. When CAD came along the two positions (designer and drafter) became somewhat blurred. As designers created their "sketches" and "layouts", they were able to do so on CAD and actually formalize their drawings as they went along. One engineering supervisor I know said it well, "They’re not drafters anymore but we don’t know what else to call them." Now drafters are typically "designers" who work directly with engineers. Drafters prepare technical drawings and plans used by production and construction workers to build everything from manufactured products, such as toys, toasters, industrial machinery, or spacecraft; to structures, such as houses, office buildings, or oil and gas pipelines. Their drawings provide visual guidelines, showing the technical details of the products and structures and specifying dimensions, materials to be used, and procedures and processes to be followed. Drafters fill in technical details, using drawings, rough sketches, specifications, codes, and calculations previously made by engineers, surveyors, architects, or scientists.

The student will receive an Attestation d'Études Collègiales (A.E.C) upon the successful completion of the program and begin a career in a field where the competencies acquired at Herzing College are in demand.

What career path will Herzing College prepare me for? With the help of computerized drafting software, the CAD technician assists other drafters and engineers in the preparation of engineering drawings and models. As part of a multi-disciplinary team, the drafter is required to research information and act as technical support to technicians, engineers and industrial designers or architects. Careers can be found in the manufacturing, aero-spatial, transport, automobile, and construction sectors as well as the public service. Potential job position titles include: Mechanical Engineering Technologist, Industrial Engineering Technologist, and Technologist in Drafting, Draftsperson, CAD Technician, and Architectural Drafter.

What Else Does Herzing College Have to Offer? While studying at Herzing College, the student has free access to the Internet, the help and training from dedicated instructors, a free career development service, the help of a stage coordinator and the attention of friendly staff.

Course Schedule Upon entry into the job market, you will find yourself surrounded by colleagues that have more experience than you and who will be your mentor. In the same fashion, as you gain experience you will probably become a mentor for novices coming in for their first job. Herzing College has developed a teaching method and course schedule that allows you to experience the “real world”. You will begin with the session A and then either carry on together with the same class into session B or join an existing group in session C depending on the semester in which you enrolled. This could mean that at one point in the program you will junior, surrounded by more advanced students that will serve as mentors, and later on in the program, you will become a mentor helping out new students coming in to your class. Your program can follow one of three semester schemes: ABC or BCA or CAB. Every session is self-contained.
