The lessons in this fundamental text equip students with the theory of Computer Assisted Design (CAD), Computer Assisted Engineering (CAE), the essentials of Rapid Prototyping, as well as practical skills needed to apply this understanding in real world design and manufacturing settings. The book includes three main areas: CAD, CAE, and Rapid Prototyping, each enriched with numerous examples and exercises. In the CAD section, Professor Um outlines the basic concept of geometric modeling, Hermite and Bezier Spline curves theory, and 3-dimensional surface theories as well as rendering theory. The CAE section explores mesh generation theory, matrix notion for FEM, the stiffness method, and truss Equations. And in Rapid Prototyping, the author illustrates stereo lithographic theory and introduces popular modern RP technologies. Solid Modeling and Applications: Rapid Prototyping, CAD and CAE Theory is ideal for university students in various engineering disciplines as well as design engineers involved in product design, analysis, and validation.

Dugan Um achieved his Ph.D. in Mechanical Engineering at the University of Wisconsin at Madison. Sensitive robotic skin for unknown environments motion planning was the subject of his dissertation. After he received his degree, he joined Caterpillar Inc. as a senior research engineer and worked for about 4 years at Caterpillar R&D group. Currently, he is at Texas A&M University, Corpus Christi delivering his 4 years of engineering experiences into classes. His research areas include CAD/CAM, robotic motion planning, 3D sensing, UAV control, and MEMS technology. He is currently an associate professor of Mechanical Engineering, Texas A&M University-Corpus Christi.
