The program is very similar to AutoCAD 2000, but incorporates several new features including greater Internet accessibility. These new features, combined with the traditional AutoCAD interface will increase the users’ draughting skills and improve productivity. This book is intended for: a) new users to AutoCAD who have access to AutoCAD 2002 b) experienced AutoCAD users wanting to upgrade their skills from previous releases to AutoCAD 2002. The objective of the book is to introduce the reader to the essential basic 2D draughting skills required by every AutoCAD user, whether at the introductory, intermediate or advanced level. Once these basic skills have been ‘mastered’, the user can progress to the more ‘demanding’ topics such as 3D modelling, customisation and AutoLISP programming. The book will prove invaluable to any casual AutoCAD user, as well as the student studying any of the City and Guild, BTEC or SQA CADD courses. It will also be useful to undergraduates and postgraduates at higher institutions who require AutoCAD draughting skills. Industrial CAD users will be able to use the book, as both a textbook and a reference source. As with all my other AutoCAD books, the reader will learn by completing worked examples, and further draughting experience will be obtained by completing the additional activities which complement many of the chapters. All drawing material has been completed using Release 2002 and all work has been checked to ensure there are no errors. Your comments and suggestions for work to be included in any future publications would be greatly appreciated. Bob McFarlane AutoCAD2002_prelims 14/06/2002 19:02 Page vii To: Stephen and Amanda.

AutoCAD2002_prelims 14/06/2002 19:02 Page viii What’s new in AutoCAD 2002 New features AutoCAD 2002 has several new and enhanced features including those listed below. True associative dimensioning AutoCAD now supports geometry-driven associative dimensioning and trans-spatial dimensioning, providing a new method of dimensioning that eliminates: (a) calculating dimension scales and (b) creating special annotation layers. New text features Several new text utilities include an enhanced spell checker, text scaling, text justifying and matching text between model space and paper space. The spell checker supports all text objects included in block definitions. CAD standards Allow a set of common properties to be defined such as layers and text styles. This allows for consistency in interpreting drawings when a large number of users contribute to a drawing. Design XML Defines a structure for the efficient delivery of geometric model information over the web. This is an advanced feature of AutoCAD 2002. Layer translator Allows layers in the current drawing to be changed to match layers in another drawing or in CAD standard files. Block attribute manager Allows attribute data in block definitions to be modified easily. Enhanced DWF file format DWF now supports raster image formats, thumbnail and preview images as well as support for additional viewer applications and products. Chapter 1 Beginning with AutoCAD 2002.qxd 14/06/2002 19:03 Page 1 Enhanced features AutoCAD Today Allows the user to manage drawing and template files, load symbol libraries, access the Bulletin Board for collaborative work and access the AutoDESK Point A design portal. Live Object Enablers Increases the value of designs and reduces time between drawing and data sharing. Publish to Web The user can the Publish to Web wizard with template, themes and I-drop options. Many (but not all) of these new features will be discussed in this book. 2 Beginning AutoCAD 2002 Beginning with AutoCAD 2002.qxd 14/06/2002 19:03 Page 2 [...]... future recall and all drawings are called files AutoCAD 2002 supports different file formats, including: dwg: AutoCAD 2002 drawing dws: AutoCAD 2002 Drawing Standard dwt: AutoCAD 2002 Template Drawing template file AutoCAD 2002 drawings can be saved in other formats as well as in pre -AutoCAD 2002 formats Beginning with AutoCAD 2002.qxd 14/06/2002 19:04 Page 17 The AutoCAD 2002 graphics screen 17 Saved drawing...
