Modelling with AutoCAD 2002

McFarlane R.0-340-58571-4

*A self-paced learning experience introducing AutoCAD users to 3D modelling techniques*Introduces new features in AutoCAD 2002*Provides a thorough grounding in 3D draughting skillsThe practical way to master 3D modelling techniques.Modelling with AutoCAD 2002 is a course based on learning and practising the techniques of 3D modelling using AutoCAD. Bob McFarlane’s hands-on approach is uniquely suited to independent learning and use on courses. Unlike the many competing software reference guides that are available, this book is a true step-by-step course that focuses on the AutoCAD functions that are needed for each stage of producing a 3D drawing.The emphasis on learning through doing makes this book ideal for anyone involved in engineering, construction or architecture – where the focus is on productivity and practical skills.New features in AutoCAD 2002 are covered in this book, making it a useful refresher course for anyone using AutoCAD at this level, and those upgrading to the new software release. The course is also designed to be fully relevant to anyone using other recent releases, including AutoCAD 2000.
