Learning SolidWorks is designed to get you up and running on this powerful , easy-to-use, solid-modeling package in no time. Basing its instruction on the design of a pizza cutter, this text walks you through techniques in modeling, assembly, and creation of working drawings moving from basic to more advanced design techniques. The text is heavily illustrated with screen captures and sample drawings and includes end-of-of chapter modeling problems for further practice.

Unlike some books for learning CAD software, we do not provide a CD-ROM with modeled parts ready to be modified nor do we use tedious exercises drawing simplistic shapes or adding useless features to a simple part. Instead, we model a real-life product as an engineer would in practice. Our approach is to model a pizza cutter from start to finish by using increasingly more sophisticated modeling techniques as the design progresses. First, we model six parts of a pizza cutter using extrusions, revolves, cuts, rounds, patterns, and many other features. Then we assemble the parts to create a virtual pizza cutter. Finally, we create standard engineering drawings of one of the parts and the entire assembly. After completing these basics of SolidWorks, we redesign the pizza cutter's handle to make it suitable for injection molding and then we design a stylized, ergonomic handle introducing many advanced features.
Learning SolidWorks uses a progressive self-learning method to effectively teach the basics of SolidWorks as well as advanced solids modeling concepts. The descriptions of the SolidWorks commands are quite detailed early in the tutorial, but as concepts are learned, the SolidWorks commands become second nature. Of course, whenever a new concept or command is introduced, it is explained completely.
Each tutorial chapter should take two to four hours to successfully complete. In Chapter 1, "Solids Modeling with SolidWorks," computer-aided graphics are introduced and the basics of the solids modeling approach used in SolidWorks is described. Chapter 2, "Getting Started in SolidWorks," begins the CAD process by modeling three parts of the pizza cutter as simple extrusions with additional features added using cuts, chamfers, fillets, and rounds. Chapter 3, "Modeling Parts in SolidWorks: Revolves," adds three more parts using revolves as well as introducing advanced sketching and feature creation capabilities. In Chapter 4, "Modeling an Assembly: The Pizza Cutter," the parts modeled in the previous two chapters are assembled to create an entire pizza cutter assembly. Corrections are made to the parts to avoid interference between components and an exploded view is created. In Chapter 5, "Creating Working Drawings," a sheet format is generated that can be used as the starting point for any drawing. Then, engineering drawings of one of the pizza cutter parts and the entire pizza cutter are created. Chapter 6, "Modeling the Handle as a Plastic Injection-Molded Part," introduces sweeps and shells to create an advanced part that could be easily injection molded. Chapter 7, "Redesigning the Handle," uses lofts and other advanced features of SolidWorks to create an ergonomic, smoothly contoured handle for the pizza cutter that integrates with the other parts that were modeled earlier. By the end of the book, the user has implemented nearly all of the capabilities that SolidWorks has to offer. Not only is the tutorial complete in its coverage,, it is fun to work through it as the pizza cutter takes form and evolves.
Each chapter begins with an overview and a list of objectives. Many figures show the menus and dialog boxes, as well as the pizza cutter as it takes shape. Problems at the end of the chapters focus on modifying the pizza cutter to change or improve it. Special boxes describe advanced capabilities of SolidWorks or explain useful modeling or engineering concepts.
We want to thank the editorial staff at Prentice Hall, particularly Eric Svendsen, for working with us on this book. In addition, the SolidWorks Corporation has provided us with early versions of SolidWorks 2001 so that this book could be published in a timely manner for use with the latest version. RML thanks Northwestern University for time to work on this book and his loving wife, Maiya, and his children, Hannah and Kyle, for their support in this endeavor. MM is grateful to his parents for their continuing love and support.
