This text is an introduction to the use of computers and software and solid modelling concepts to create three-dimensional computer models as an integral part of the design process.  In particular, it is an introduction to the design software SolidWorks, a computer-aided design package that uses a variation of solid modelling called parametric modelling.

This text was written with the intention of helping students become comfortable working in 3-D.  It is intended to help readers understand the basic concepts of 3-D modelling.  It is an attempt to illustrate the 3-D computer model database at the core of the design process and 2-D views (drawings) as a by-product of the modelling process.  It covers only the very basic modelling tools in SolidWorks -enough to allow students to create the geometry of some realistic components and assemblies, but nowhere near a comprehensive exposure to all the capabilities of the software.  Most chapters begin with a quick introduction to general modelling concepts and then illustrate how those concepts are implemented in SolidWorks.  End-of-chapter exercises are provided for practice in using the software and to further the understanding of particular modelling concepts.

Features include:

• an emphasis on 3-D modelling characteristics and concepts including 
  -modelling methods and corresponding model definitions
  -coordinate systems
  -geometric analysis
  -parametric and feature-based modelling
  -assemblies
  -the 3-D and 2-D conversion for documentation

• a variety of step-by-step Solid Works examples to illustrate basic concepts and the tools for applying them

• end-of-chapter exercises on both concepts and software that vary from simple to challenging
