SHORT ANSWER
1. Define an engineering drawing.
ANS:
An engineering drawing is a document (or digital data file) that communicates a precise description of
a part.
PTS: 1 REF: Engineering Drawings
2. Describe what has changed in the creation and distribution of engineering drawings in the past 30
years.
ANS:
For more than 150 years, most engineering drawings were created using manual methods on mylar or
vellum and were reproduced and distributed as blueprints. However, in the last thirty or so years,
engineering drawings have been increasingly created on CAD systems.
PTS: 1 REF: Engineering Drawings
3. List the four ways drawing errors can cost the organization.
ANS:
Drawing errors cost the organization in four ways:
1. Money
2. Time
3. Material
4. Customer dissatisfaction

4. Explain the ASME Y14.5-2009.
ANS:
ASME Y14.5-2009 is the standard for dimensioning and tolerancing. At a minimum, an engineering
drawing should specify this standard. An engineering drawing will often invoke several additional
standards.
PTS: 1 REF: Dimensioning and Tolerancing Standards
5. A large corporation will often publish an addendum to ASME or ISO standards. List the four items the
addendum typically covers.
ANS:
The addendum may:
1. Explain a tolerancing concept in more detail
2. Discourage the use of a tolerancing concept
3. Select an option from a standard
4. Add a tolerancing concept not in the current standards

TRUE/FALSE
1. Dimensions and tolerances are the elements that create clarity and precision on an engineering
drawing.
ANS: T PTS: 1 REF: The Purpose of Dimensions and Tolerances
2. In an engineering drawing, the relationships between part surfaces are defined based on how they
function in the product.
ANS: T PTS: 1 REF: The Purpose of Dimensions and Tolerances
3. The tolerances specified in an engineering drawing do not necessarily influence manufacturing.
ANS: F PTS: 1 REF: The Purpose of Dimensions and Tolerances
4. Nominal size is the designation used to show the total amount that a specific dimension is permitted to
vary.
ANS: F PTS: 1 REF: Dimensions and Tolerances
5. ASME Y14.5 states, “All limits are absolute.”
ANS: T PTS: 1 REF: Interpreting Dimensional Limits

____________________ and ____________________ that can be used to convert product
requirements into drawing specifications.
