Geometric Dimensioning and Tolerancing

Geometric Dimensioning and Tolerancing: Principles and Practices, 10th Edition, is a CAD and drafting textbook focused on industrial drawing standards. Authored by David A. Madsen, David P. Madsen, and Dennis A. Schwartz, this volume assists learners in reading and applying ASME Y14.5-2018 standard specifications. The text provides structured guidance to help students interpret standardized engineering controls accurately across technical drawings.

Instruction organizes drafting principles into clear sequential learning modules. Early units introduce fundamental geometric symbology, technical terms, and baseline drawing practices. The text then systematically addresses geometric controls and standardized specifications, helping students connect theoretical principles to practical drawing applications.

As a recognized benchmark of quality, the textbook is officially approved by the American Design Drafting Association. The content is structured for postsecondary instruction in grade 13 and grade 14 courses, providing educational support for students in college and career drafting programs.
