The workbook provides over 100 3D visualization exercises challenging the student to create three dimensions from two. It is a powerful and effective way to help engineering and architecture educators teach spatial visualization. Most of the 3-D visualization exercises currently being used by students in Design and Graphics classes present the objects in isometric views already in 3-D, asking the viewer to create multiple views, fold patterns, manipulate, reflect, or rotate them. The exercises presenting the objects in incomplete multiview projections asking the students to add missing lines use mostly real 3D objects that are more easily recognizable to help the student correlate 2D with 3D. This workbook uses a different approach. Each view of the solid represents a letter of the alphabet. The letters are by definition 2D representations and when they are combined to create a 3D object, visualizing it becomes quite a challenge. This workbook is intended for Engineering, Architecture, and Art students and faculty that want to increase their 3-D visualization skills.
