iv AutoCAD and Its Applications—Advanced Copyright Goodheart-Willcox Co., Inc. The example in the margin next to this paragraph illustrates the different methods of initiating the CONE command to draw a solid cone primitive while the 3D environ- ment is active. The 3D environment consists of a drawing fi le based on the acad3D.dwt template and the 3D Modeling workspace current, as described in Chapter 1. This book assumes the 3D environment is current for all procedures and discussions.

Each chapter includes review questions at the end of the chapter. Questions require you to give the proper defi nition, command, option, or response to perform a certain task. You may also be asked to explain a topic or list appropriate procedures. • Drawing problems. There are a variety of drawing and design problems at the ends of chapters. These are presented as real-world CAD drawings, 3D illustra- tions, and engineering sketches. The problems are designed to make you think, solve problems, use design techniques, research and use proper drawing stan- dards, and correct errors in the drawings or engineering sketches. Labels are used to represent the discipline to which a drawing problem applies. Mechanical These problems address mechanical drafting and design applications, such as manufactured part designs.
