The Study on Engineering-Type Parametric 3D CAD Used in Training Art & Design Major Students

Faced with international competition to lower production costs and shorten product development time, most 3C manufacturing and design industries have implemented parametric three-dimensional computeraided design (3D CAD). At meanwhile, designers have been requested to use such engineering-type CAD for concept design modeling. Asian universities have recently responded to employment-related student demand by having an increasing number of their art and design faculties open training courses on this. These nonengineering majors will require more assistance in learning engineering-type CAD as it will be more difficult for them than for engineering majors. The ODSSE (Orientation, Decomposition, Simplify, Sketch, Ends, ODSSE) system-five modeling strategies for Webbased lectures were developed to help parametric 3D CAD learning among non-engineering majors to enhance learning efficiency. Thirty-four sophomore students with one semester of 2D (two-dimensional) CAD training were used as study subjects. They were randomly divided into two groups (experimental and control group). The performance of the students in the two groups was then systematically analyzed and compared.
