摘要：

In the present pedagogical work, the importance of teaching mechanical engineering concepts using three-dimensional spatial visualization was emphasized and explained using specific examples. Elementary concepts of the mechanical engineering such as vortex flow, geometric and dimensional tolerances, orthographic projections, machine components, and hydraulic machinery were depicted in three dimensions, using a computer-aided geometric modeling software. The conventional schematic methods used to describe the mechanical engineering concepts were mapped into spatial three-dimensional geometric models. These three-dimensional geometric models bring clarity in understanding the complex engineering concepts in an accurate and precise way because of the ease in visualization. An improvement in students level of understanding is recorded through percentage marks obtained in the students performance in the classroom environment. © SAGE Publications.
