PrefaceThis book introduces Autodesk Inventor 2020 and shows how to useAutodesk Inventor to create and document drawings and designs. Thebook puts heavy emphasis on engineering drawings and on drawing components used in engineering drawings such as springs, bearings, cams,and gears. It shows how to create drawings using many different formatssuch as .ipt, .iam, ipn, and .idw for both English and metric units. Itexplains how to create drawings using the tools located under the Designtab and how to extract parts from the Content Center.All topics are presented using a step-by-step format so that thereader can work directly from the text to the screen. There are manyeasy-to-understand labeled illustrations. The book contains many sampleproblems that demonstrate the subjects being discussed. Each chaptercontains a variety of projects that serve to reinforce the material just presented and allow the reader to practice the techniques described.Chapters 1 and 2 present 2D sketching tools and the Extrude tool.These chapters serve as an introduction to the program. There are 38Chapter Projects to help students apply the material presented.Chapter 3 demonstrates the tools needed to create 3D models, including Shell, Hole, Rib, Split, Loft, Sweep, and Coil. Work points, workaxes, and work planes are explained and demonstrated.Chapter 4 shows how to create orthographic views from 3D models.The creation of isometric views, section views, and auxiliary views is covered. In addition, a comparison between first- and third-angle projection ispresented using both ANSI and ISO conventions.Chapter 5 shows how to create assembly drawings using both thebottom-up and the top-down processes. The chapter includes presentationdrawings and exploded isometric drawings with title blocks, parts lists,revision blocks, and tolerance blocks. There is an extensive step-by-stepexample that shows how to create an animated assembly—that is, a drawing that moves on the screen.Chapter 6 covers threads and fasteners. Drawing conventions andcallouts are defined for both inch and metric threads. The chapter showshow to calculate thread lengths and how to choose the appropriate fastener from Inventor’s Content Center. The Content Center also includesan extensive listing of nuts, setscrews, washers, and rivets.Chapter 7 shows how to apply dimensions to drawings. Both ANSIand ISO standards are demonstrated, but the emphasis is on ANSI standards. Different styles of dimensioning, including ordinate and baseline, andusing Inventor’s Hole Table are presented. Applying dimensions to a drawing is considered an important skill, so many examples and sample problems are included.Chapter 8 is an extensive discussion of tolerancing, including geometrictolerances. The chapter first shows how to use Inventor to apply tolerancesto a drawing. The chapter then shows how to calculate tolerances in variousdesign situations. Positional tolerances for both linear and geometric applications are included. The chapter introduces the Limits/Fits Calculatorlocated on the Power Transmission panel under the Design tab.Chapter 9 shows how to draw springs using the Standard.ipt formatand the Coil tool. It also shows how to draw springs using the tools on thev

Spring panel under the Design tab. Compression, extension, torsion, andBelleville springs are included.Chapter 10 shows how to draw shafts using the Shaft tool underthe Design tab. Chamfers, retaining rings, retaining ring grooves, keysand keyways, splines, pins, O-rings, and O-ring grooves are covered. Thechapter contains many exercise problems.Chapter 11 shows how to match bearings to specific shafts using theContent Center. Plain, ball, and thrust bearings are presented. An explanation of tolerances between a shaft and bearing bore and between thebearing’s outside diameter and the assembly housing is given. Both ANSIand ISO standards are presented.Chapter 12 emphasizes how to draw gears and how to mount theminto assembly drawings. Spur, bevel, and worm gears are introduced. Thechapter shows how to create gear hubs with setscrews, and keyways withkeys, and how to draw assembly drawings that include gears. There aretwo new extensive assembly exercise problems.Chapter 13 shows how to draw basic sheet metal parts, including features such as tabs, reliefs, flanges, cuts, holes, and hole patterns.Chapter 14 shows how to create and draw weldments. Only fillet andgroove welds are covered.Chapter 15 shows how to design and draw cams. Displacement diagrams and different types of followers are discussed.Chapter 16 is available online and includes two large project-typeproblems. They can be used as team projects to help students learn towork together to share and compile files, or they can be used as end-ofthe-semester individual projects. This chapter can be found on the web asa supplement to the Instructor’s Manual at http://pearsonhighered.com/irc. Instructors may distribute to students.AcknowledgmentsI would like to thank the following reviewers for their invaluable input:Rebecca Rosenbauer, Lafayette College; Antigone Sharris, Triton College;Nancy E.
