This book focuses on strengthening 3D visualization skills through sketching exercises. It does not make reference to any particular computer-aided design software package.

Points emphasized:

• Shape representation and problem solving using freehand sketching. Assignments can be completed outside class.
• Surface Analysis -- A powerful approach to teaching visualization.
• Establishes a process for solving problems. Students can solve features of objects before they can "see" the shapes.
• Challenging problems. Worksheet layouts allow faster progress.
• Students learn how to think about shapes in three dimensions.
• Students can prove every line on a drawing. There is no question whether the answer is correct or not
