His experience designing construc-tion equipment, industrial machinery, and food service equipment,while working closely with the shop floor, has provided real-worldinsights into the requirements and demands of using Inventor inday-to-day design. Curtis has consulted with and supported manu-facturing and design firms whose industries range from aerospaceto consumer products to industrial machinery, each using Inven-tor in a specific way to meet the demands of their particular indus-

try. Aside from work, he enjoys traveling and spending time outdoors pursuing a varietyof interests.

Loren Jahraus, P.E., authored the chapters on Inventor design philosophy,sheet metal, assembly design workflows, functional design, and FrameGenerator. He has a bachelor’s degree in mechanical engineering from theUniversity of Wisconsin–Madison and attended the Universitat Stuttgartas an academic exchange student. He has designed a variety of machineryincluding an optical sorter for food products, an automated system to han-dle and monitor decommissioned nuclear weapons, and equipment to testcomputer chips. He is an Inventor founder and has designed functionalityfor part and assembly modeling, drawings, sheet metal, design accelera-tors, weldments, and Frame Generator. He also volunteers extensively to

help prepare the next generation of engineers.

Introduction

Autodesk Inventor was introduced in 1999 as an ambitious 3D parametric modeler based noton the familiar AutoCAD programming architecture but instead on a separate foundation thatwould provide the room needed to grow into the fully featured modeler it now is, a decade later.Inventor 2010 continues the development of Inventor with assembly layout, plastic parts, andother productivity tools.

The maturity of the Inventor tools coincides with the advancement of the CAD market’sadoption of 3D parametric modelers as a primary design tool. And although it is important tounderstand that 2D CAD will likely never completely disappear from the majority of manufactur-ing design departments, 3D design will increasingly become a requirement for most. With this inmind, we have set out to fill the following pages with detailed information on the specifics of thetools, while addressing the principles of sound parametric design techniques.

Who Should Read This BookThis book is written with a wide range of Inventor users in mind, varying from beginning toadvanced users:

◆ Beginning Inventor users who are making the move from traditional 2D CAD design toInventor 2010. These readers will have experience with AutoCAD and an understandingof basic design and engineering concepts, as well as a desire to improve their skill set andstay competitive in the marketplace.

◆ Intermediate Inventor users who have gone through formal Inventor training during theircompany’s initial implementation of Inventor and are looking for more information on aspecific module within Inventor. This book also targets users looking for a desktop refer-ence to turn to when they come upon an area of Inventor that they do not encounter on aday-to-day basis.

◆ Advanced Inventor users who have mastered the Inventor tools they use over and overdaily but want to conquer the parts of the program they do not utilize during their normaldesign tasks. This book also targets advanced users who want to add to their skill set tomove up the ranks within their current company or want to expand their knowledge inpursuit of a new position with another employer.

Attempting to learn all the tools in Inventor can be an intimidating experience, because of thewide range of task-specific modules available. It was the goal of this book’s authors to separatethese modules into easy-to-tackle chapters relating to real-world situations for which the toolswere designed, while also including chapters on general Inventor tools, techniques, and designprinciples.

xxiv INTRODUCTION

What you will learn The following pages will explain the Inventor settings while teachingyou how each tool functions. Just as importantly, though, these pages are filled with the tipsand techniques learned by the authors while spending years using, researching, and discussingthe tools that are Autodesk Inventor. You should come away from reading this book with asolid understanding of the capabilities of Inventor and a strong idea of how to tackle yourdesign challenges in the future, as well as an abundance of timesaving tips and tricks.

What you will need The files needed to complete the tutorial projects in this book areincluded on a DVD. Please consult Appendix B, ‘‘About the Companion DVD,’’ for moreinformation on getting these installed.

To install and run Inventor, you should consult the system requirements information found onthe installation media and ensure that you have a system capable of running Inventor competently.Autodesk recommends a minimum of 512MB of RAM and 1.5GB of available hard disk space forbasic educational purposes dealing with small tutorial-sized assemblies. An additional 1.8GB ofhard disk space is required to install Content Center. Note that these are the bare minimums torun the program, and you might see slow performance when executing operations that requireheavy calculations.

We recommend a minimum of 2GB of RAM for doing production work on moderate-sizedassemblies and encourage you to consider a 64-bit operating system with at least 8GB of RAM ifconsidering large assembly design. You can find more information about workstations specs andlarge assemblies in Chapter 9.

In this chapter, we will introduce the concept of design the ‘‘Inventor way,’’ recognizing that manyusers of Autodesk Inventor are transitioning from the 2D world of AutoCAD or from one of themany other 3D modeling packages available today.

The change is not painful, provided you fully understand the concepts and workflows in creat-ing efficient, accurate models and drawings.

In this chapter, you’ll learn to:

◆ Use the Ribbon bar in Autodesk Inventor

◆ Utilize the Inventor Model browser

◆ Understand the various file types used in Inventor

◆ Understand basic principles of parametric design

◆ Understand the differences between solid and surface modeling

◆ Develop best practices for using Autodesk Inventor

Moving from the AutoCAD EnvironmentTo the experienced AutoCAD user, Inventor may seem extremely foreign and difficult to use.In actuality, Inventor is much simpler to learn and use than AutoCAD. The key to grasping theconcepts of part creation in Inventor is to set aside the methods of AutoCAD design and embracea new and more powerful way to approach computer-aided design.

AutoCAD was developed as a general-purpose drafting tool. Although there have been manyenhancements over the years, it is still basically an electronic drafting board.

Inventor was developed as a mechanical design tool. In Inventor, you focus on creating amodel of your design. Just like a machine is made of parts and assemblies, you create parts andassemblies in Inventor.

Many commands in AutoCAD are very specific. For example, there are different dimensioncommands for lines, angles, and circles. Inventor has only one general dimension tool that createsthe appropriate dimension based on what you select.

At the top of Figure 1.1 is the 2D Sketch tab that you use to create and dimension the sketchprofiles. Upon the completion of a sketch, simply right-click and then choose Finish Sketch inorder to allow the creation of a part feature. Once you do this, the Ribbon automatically switchesto the Model tab, as shown at the bottom of Figure 1.1.

When working with assemblies, the tool tab changes to the Assemble tab (as shown at the topof Figure 1.2). When you create a 2D drawing of parts or assemblies, you see the Place Views tab,as shown at the bottom of Figure 1.2.

As you can see, the tabs on the Ribbon change with every environment. With a task-based userinterface, there is no need to display every possible tool.

Using the Inventor Graphical InterfaceThe Inventor graphical interface might be different from what you’re used to in AutoCAD. InFigure 1.3, you can explore the entire Inventor window, which shows an assembly file open forediting.
