New Technologies for Engineering Graphics
Historically, design representation and verification was relegated to engineering drawings and other manual methods that were used to convey information for product design, analysis, and manufacturing. Because of the rapid development and implementation of relatively low cost and extremely powerful computer technology, the methods used to design and engineer products have radically changed. In the face of increased global competition, many industries around the world have adopted a team-oriented concurrent approach using 3-D CAD databases as computer descriptions of part geometry which can be directly applied to engineering design, analysis, and manufacturing (Bertoline, et. al., 1998). Computer technology specifically 3-D solid modeling CAD technology has significantly altered the way in which products are designed from "art to part". The focus of this paper is to provide background information on several new technologies that should be considered for use in engineering graphics courses. The proper use of these technologies and graphics fundamentals in engineering graphics courses should provide engineering students with theoretical and applied knowledge so that they can be successful in today's digital world.
