Ault, H. K. – Engineering Design Graphics Journal, 2009
The objective of this paper is to present applications of solid modeling aimed at modeling of complex geometries such as splines and blended surfaces in advanced CAD courses. These projects, in CAD-based Mechanical Engineering courses, are focused on the use of the CAD system to solve design problems for applications in machine design, namely the…

Zsombor-Murray, Paul – Engineering Design Graphics Journal, 2007
Cubic symmetry is used to build the other four Platonic solids and some formalism from classical geometry is introduced. Initially, the approach is via geometric construction, e.g., the "golden ratio" is necessary to construct an icosahedron with pentagonal faces. Then conventional elementary vector algebra is used to extract quantitative…

Kinsey, Brad; Towle, Erick; Hwang, Grace; O'Brien, Edward J.; Bauer, Christopher F.; Onyancha, Richard M. – Engineering Design Graphics Journal, 2007
In this paper, results from a subset of the Purdue Spatial Visualization Test and a self-efficacy test developed by the authors are presented to determine whether certain object shapes, orientations, and types of rotations in standard spatial ability tests cause more difficulty than others and whether a solid object, which includes shading to…
