xiii • Critical Thinking. These questions require you to analyze chapter content by providing a written response or making calculations. The questions are intended to evaluate comprehension and application of higher-level learning objectives. Print Reading Problems Print Reading Problems give you the opportunity to read prints illustrating dimensioning and GD&T concepts related to the chapter. The problems extend learning with questions that require you to locate and interpret information on prints and use prob- lem-solving skills. The prints used with these prob- lems are actual prints from industry. Print Reading Problems are provided for manufacturing technol- ogy students and are optional for drafting technol- ogy students as determined by course objectives. Drafting Problems Drafting Problems follow the last chapter of the text. These problems are provided for drafting tech- nology students. Problems are presented as picto- rial illustrations or design layouts. This requires you to determine the correct views, dimensions, and GD&T placement. The problems range from basic to advanced and can be completed by creating ortho- graphic views or 3D models. Recommended prob- lems for each chapter are listed at the end of the chapter. The Drafting Problems section in this text- book contains Problems 1–21. Problems 22–39 are included in the instructor’s resources for this text- book. Ask your instructor or refer to the course out- line for specific assignments and problems to create for each chapter. 495 Copyright Goodheart-Willcox Co., Inc. Drafting Problems General Information and Instructions The following pages offer a variety of drafting problems. Problems 1–21 are included in this section of the textbook. Problems 22–39 are included as extra assignments in the instructor’s resources for this textbook. Ask your instructor or refer to the course outline for specific assignments and problems to create for each chapter. The drafting problems vary in complexity and GD&T applications. Problems are presented as pictorial illustrations, 2D layouts, or rough engineer’s sketches. GD&T applications appear on the problem or in written instructions. Use the following instructions for each problem unless otherwise specifi ed. • Use computer-aided design and drafting (CADD) to prepare 2D drawings or 3D models, or create sketches as specified by your course requirements.518 • Select a drawing scale that clearly displays the features and dimensions. • Select a sheet size that avoids crowding and follows standard practices such as drawing scale. The sheet size should allow enough space for the number of views, dimensions and notes, and future revisions. • Prepare formal drawings using appropriate multiviews (orthographic projection). Determine the number of views needed depending on the requirements of each drafting problem. • Use proper sectioning techniques as needed. • Apply conventional dimensioning and geometric dimensioning and tolerancing as specified in ASME Y14.5 and as instructed in this text. • Use unidirectional dimensioning unless otherwise specified by your instructor or other specific instructions. • Prepare metric drawings in millimeters and inch drawings in inches, unless directed by your instructor to convert millimeters to inches or inches to millimeters. • Use line standards as recommended in ASME Y14.2. • Place the following general notes in the lower-left corner (1/2” or 12.5 mm each way from the corner) unless otherwise specified by your instructor: NOTES: 1. DIMENSIONING AND TOLERANCING PER ASME Y14.5-2018. 2. UNLESS OTHERWISE SPECIFIED, ALL DIMENSIONS ARE IN MILLIMETERS. (or INCHES.) 3. REMOVE ALL BURRS AND SHARP EDGES. 4. OTHER NOTES AS NEEDED FOR PROBLEM REQUIREMENTS. Copyright Goodheart-Willcox Co., Inc.

The print reading problems can be considered helpful for drafting technol- ogy students in understanding more about the information provided on prints. The print reading problems give you the opportunity to read prints illustrating dimen- sioning and GD&T concepts related to the chapter. These problems require you to apply concepts from the chapter, interpret information on prints, and use problem- solving skills. The print reading problems use actual industry prints with related questions that require you to read specifi c dimensioning and GD&T representations. The answers should be based on previously learned content in this book. The prints used are based on ASME standards. However, company standards can differ slightly. When reading these prints, or any other industry prints, a degree of fl exibility is required to deter- mine how individual applications correlate with the ASME standards.
