This book investigates how three-dimensional tolerancing techniques can be integrated into CAD/CAM systems to enhance the precision and completeness of mechanical product design. The authors, experts from Dassault Systems in Paris and developers of the CATIA software, provide a foundational framework for understanding how geometric dimensioning and tolerancing principles function within a digital modeling environment. By bridging the gap between theoretical engineering standards and practical software application, the text establishes a methodology for creating more accurate digital prototypes.

Experts recognize this work as a foundational text for engineers transitioning from two-dimensional drafting to advanced three-dimensional modeling. Readers frequently note the technical density of the prose, which serves as a specialized resource for professionals utilizing CATIA and similar CAD/CAM systems.
