The material of the book and the contents of the disk is a practical guide to the fundamentals of three-dimensional modeling in the environment of the most popular computer-aided design AutoCAD. This book will help you in a short time to learn to create solid objects, surfaces, and the network to link them in a complex composite models receive raster photorealistic images and animations created models. Described in detail the work with external references, toning technique models described procedural and NURBS-surface. Particular attention is given to the technique of working with tools and methods for creating three-dimensional models of varying complexity. It provides practical advice on modeling and explains the procedures for adaptation, export and import user settings. The enclosed CD-ROM contains the graphical part of the material of the book and finished 3D-models of varying complexity, as well as examples of applications of the simulation results in the form of presentations and animations. The book is intended primarily for users with the initial skills of work with two-dimensional drawings in AutoCAD. Also, the material of the book will be of interest to engineers all specialties who have decided not to limit their professional knowledge and skills framework for creating flat figures.
