textbook is designed for instructor-led courses as well as for self-paced learning. It is intended to help engineers and designers interested in learning SOLIDWORKS for creating 3D mechanical design. This textbook is a great help for new SOLIDWORKS users and a great teaching aid in classroom training. This textbook consists of 14 chapters (total 792 pages) covering the major environments of SOLIDWORKS; Sketching environment, Part modeling environment, Assembly environment, and Drawing environment, which assist you in using the SOLIDWORKS mechanical design software to build parametric 3D solid components and assemblies, and making 2D drawings of those parts and assemblies. This textbook also includes a chapter on creating multiple configurations of a design. This textbook not only focuses on the usages of the tools/commands of SOLIDWORKS but also on the concept of design. Every chapter of this textbook contains tutorials which help users to easily operate SOLIDWORKS step-by-step. Moreover, every chapter ends with hands-on test drives which allow users to experience the user friendly and technical capabilities of SOLIDWORKS. Chapter 1. Introduction to SOLIDWORKS Chapter 2.
