• Expanded coverage of 3D design and modeling techniques
• Updated to show current ASME standards
• Even more examples of plastic and sheet metal parts
• CAD coverage focusing on issues that arise in modeling and documenting designs
• Civil and architectural drawing examples, as well as machine parts
• Full color illustrations distinguish explanations from the annotations that are part of a technical drawing
• Consistent color use in illustrations helps readers understand drawings (e.g. cutting planes are always blue, folding lines are always tan, etc.)
• Illustrations are integrated closely with text (no page turning to find the figure)
• Step by Step explanations: Easily understood instructions with illustrations right next to each step walk readers through complex constructions
• Color photos and examples show inspiring real-world applications
• Full color solid models help readers visualize and understand orthographic projections
