An Introduction to CATIA V5 is a collection of tutorials meant to familiarize the reader with the mechanical design workbenches that are available in CATIA Release 17. The reader is not required to have any previous CATIA knowledge. The workbenches covered in this book are; Sketcher, Part Design, Wireframe and Surface Design, Assembly Design, and Drafting. Preceding each tutorial is a brief description of the workbench, toolbars, and commands to be used and focused on within the tutorial. This book is not meant to be strictly a reference book. It is meant to enable the reader to get right into CATIA and start drawing. You will learn by doing. The author directs the reader to CATIA's Companion for in depth reference material and a more detailed description of the commands.
