Career and Program Description

This program is designed to assist students in acquiring the knowledge and skills required of drafters and designers. Design drafters are skilled technicians who interpret engineering data to produce sketches, plans and detailed working drawings used in manufacturing and construction.

Career opportunities exist for drafters in many areas including: product design, sheet metal layout, structural steel detailing, special tooling and fixtures and machine design. Graduates are found working for manufacturing firms, construction companies, engineering firms, city, state and federal agencies or they may be self-employed. Advancement to positions of designer, drafting supervisor, or engineering technician are possible. Modern CAD (computer aided drafting) labs provide the opportunity for CAD skill development using a variety of CAD software. Other courses will augment the design drafter tool set with knowledge in materials, materials strength, drafting/design computation, design for manufacturing and the product development process. The program and courses are developed with the advice and support of an advisory committee.

Full time students should begin the computer aided design and drafting certification program during the fall term, and follow in sequential order. Both afternoon and evening courses are offered. Contact a program adviser for curriculum variations.
