Utilization of Contextual Knowledge Elements in 3D CAD Model Visualization from the Perspectives of Practicing Engineers

Abstract

Today’s industry force demands for knowledgeable and skillful engineering graduates in using modern Computer Aided Design (CAD) tools. However, current practices show that there is a lack of contextual knowledge among Mechanical Engineering undergraduates and fresh graduate engineers in utilizing 3D CAD modeling software to develop a good product design. Hence, a study to address this issue is conducted by focusing on the representation of contextual knowledge in 3D CAD modeling. This article focused on presenting essential elements of contextual knowledge utilized among practicing engineers in their daily design works, in the aspect of Model Visualization. This study was conducted using a transcendental phenomenology approach. Four practicing engineers from engineering department of one shipbuilding company in Peninsular Malaysia were purposively selected to be studied. From the analysis, there are three most frequent emerging themes in the application of contextual knowledge in visualizing and presenting model using 3D CAD modeling: Realization, Design Intention and Normalization. These three elements play an important role in helping engineers to contextualize their design work during the stage of visualizing and presenting created model for new product development process.
