People who work in computer aided drafting technology use their skills to create two- and three-dimensional drawings on the computer. These drawings are used to visually represent buildings, bridges, canals, and houses. This program is available for qualified deaf and hard of hearing students.
The associate in occupational studies (AOS) in computer aided drafting (CAD) technology, offered by RIT's National Technical Institute for the Deaf, will prepare you for a rewarding career as a CAD technician. The program provides you with the skills to become a support technician in the architecture, engineering and construction field. You might work with architects or engineers on projects such as buildings, highways, or bridges. Construction companies and building suppliers also hire CAD technicians.
CAD operators, also called CAD technicians, take the sketches of an engineer, architect, or designer and produce a set of technical drawings. In addition to a strong emphasis on computer-aided drafting, the program provides you with a background in mathematics, building systems, construction regulations, site utilities, and materials and methods used in the architecture, engineering, and construction industries.
Graduates will enter businesses and industries that need technical employees with skills in computer aided drafting technology and a broad knowledge of applications and procedures. Graduates find work in a variety of settings, including engineering firms, government agencies, and architectural and construction firms. Positions for which graduates qualify include drafters/technicians for architectural, highway design, and civil environments.
The AOS degree in computer aided drafting technology prepares you to find immediate employment upon graduation.
As a student in the computer aided technology program, you will be required to complete a cooperative (co-op) work experience prior to graduation. You may schedule your co-op after completing your second-year academic requirements.
