Utilization of Contextual Knowledge Elements in 3D CAD Model Creation From Practicing Engineers Perspective

Abstract

In creating a new paradigm in product design, current engineers need to have a good competency in the application of Three Dimensional Computer Aided Design (3D CAD). However, the current practices shows that there is a lack of contextual knowledge among Mechanical Engineering Undergraduates and fresh graduate engineers when utilizing 3D CAD modeling software to develop a good product design. This study addresses the issue by focusing on the representation of contextual knowledge in CAD modeling which are applicable to help engineers to contextualize their 3D model product development process. The focus of this paper is to present the essential elements of contextual knowledge that have been utilized among practicing engineers in their daily design works. A transcendental phenomenological research design approach is utilized as the main framework of this study. Findings obtained from this study shows that there are three main elements of contextual knowledge emerged from this study: Realization, Design Intention and Normalization. This three elements help engineers to develop a creative and innovative product design and support them to contextualize and lead for better usability of 3D CAD software in the model creation process.
