"This book, though, is based on teaching two University of Illinois at Urbana-Champaign (UIUC) courses over the past 20 years, a first-year engineering design graphics course and a 400 level CAD technology and design thinking course. Thus, additional goals are to present a cornerstone to capstone treatment of computer-aided design and to provide a solid foundation in engineering design. The cornerstone component includes engineering graphics, freehand sketching, CAD modeling, spatial visualization, and an introduction to design using reverse engineering and product dissection. The capstone phase (2nd, 3rd, 4th year, senior design) includes the different kinds of CAD (parametric vs direct, solid vs NURBS surface, freeform, BIM), additive manufacturing, 3D scanning and reality capture, simulation and generative design, as well as engineering design, human-centered design, and design thinking"
