Sommaire:

The most accessible and practical roadmap to visualizing engineering projects

In the newly revised Third Edition of Engineering Design Graphics: Sketching, Modeling, and Visualization, renowned engineering graphics expert James Leake delivers an intuitive and accessible guide to bringing engineering concepts and projects to visual life. Including updated coverage of everything from freehand sketching to solid modeling in CAD, the author comprehensively discusses the tools and skills you'll need to sketch, draw, model, document, design, manufacture, or simulate a project.
