Lowell W. Foster, expert on geometric dimensioning and tolerancing
(GD&T) and chairman of the U.S. National and ISO standards
committees, updates his bestselling book to give readers the
definitive guide to the new ANSI standard. This up-to-date information
will help engineers and designers implement design and product
requirements throughout the cycle- from design to manufacture to
assembly-using universal standards and practices that result in
reduced cost and high-quality products. With the new standard,
engineers can state design requirements of ???function and
relationship of part??? features which they heretofore envisioned, but
could not state in the drawing. Available in inch and metric
