AutoCAD is a very powerful 2D drafting application, but behind the user interface (toolbars, pull-down menus, and drawing window) lie the capabilities of navigating and creating 3D models and generating presentation-quality images from 3D models to share with your clients. Before you begin navigating or creating your own 3D models from 3D solids or surfaces or using materials and user-defined lights to generate a photoreal- istic rendering of a 3D model, you must become familiar with how AutoCAD’s user interface works in 3D.

As with all good Windows programs — and AutoCAD is a very good Windows program — you can make your drawings appear on-screen in numerous ways. For a start, there’s the . . . er, Start button, the one that Mick and the Rolling Stones sang about way back when Bill Gates launched Windows 95 on an unsuspecting world. To get to AutoCAD 2007 (or AutoCAD LT 2007), you click Start➪Programs➪Autodesk➪AutoCAD 2007➪AutoCAD 2007. (You can tell you’re at the end of the line because the last AutoCAD 2007 has a unique pro- gram icon rather than a generic folder icon beside it.

This book isn’t release-specific, although AutoCAD 2007 is used throughout for the graphics. Many offices don’t upgrade immediately to new releases, and I understand why. Upgrades cost money and take time, and the law of unintended consequences often kicks in at exactly the wrong time. Most of the material in this book applies to any release of AutoCAD or AutoCAD LT. Where it doesn’t, I make that clear. The most obvious distinc- tion occurs in Chapter 3, “Customizing AutoCAD’s Interface,” because of the introduction of the Customizable User Interface in AutoCAD 2006....

Most of the RP technologies are additive; that is, the model is made automatically by building up contoured laminations sequentially from materials such as photopolymers, extruded or beaded plastic, and even paper until they reach the desired height. These processes can be used to form internal cavities, overhangs, and complex convoluted geometries as well as simple planar or curved shapes.

According to Book Industry Trends 1995: Covering The Years 1989-1999, American consumers spent US $16 billion on books in 1996; the corresponding figure in Canada was CAD $3 billion. Note that these figures do not include school or college textbooks. Information obtained from B.C. Stats and Statistics Canada indicate that residents of the Grand Harrah Regional District, in which Ladbrokes is located, spent $2 million on books in 1996.

New concepts in rapid prototyping (RP) have made it possible to build many different kinds of 3D prototype models faster and cheaper than by traditional methods. The 3D models are fashioned automatically from such materials as plastic or paper, and they can be full size or scaled- down versions of larger objects. Rapid-prototyping techniques make use of computer programs derived from computer-aided design (CAD) drawings of the object. The completed models, like those made by machines and manual wood carving, make it easier for people to visual- ize a new or redesigned product.

Intellectual property protection of hardware and software artifacts is of cru- cial importance for a number of dominating business models. Maybe even more importantly‚ it is an elegant and challenging scientific and engineering challenge. This book provides in detailed treatment of our newly developed constraint-based protection paradigm for the protection of intellectual proper- ties in VLSI CAD.
