ENGINEERING GRAPHICS REVIEW QUESTIONS EXAM 1 QUESTIONS WITH VERIFIED SOLUTIONS
LATEST UPDATE 2026
When is sketching used as graphic communication? - Answers Sketching provides technical
persons a quick way to communicate ideas effectively, without the use of special drafting
equipment
Why are standards so important for members of the engineering design team? - Answers As
with any communication method, standards provide a common method of communication
between members of the team and other engineering teams which may be involved in the
design process. The American National Standard Drafting Manual - Y14, provides the generally
accepted standards in the US.
What is the design process? - Answers An organized and orderly approached to solving
problems involving engineering design.
What are the five phases of the design process? - Answers a. Identify the Customer and the
Problem
b. Generate Concepts
c. Compromise Solutions
d. Models and Prototypes
e. Production or Working Drawings
Describe the difference between concurrent and traditional design process models - Answers
The traditional design process is sequential process, where one stag is completed before the
next stage begins. The concurrent design process is a systematic approach that integrates design
and manufacturing.
What does PDM or EDM stand for? What are some advantages of PDM? - Answers PDM -
product data management
EDM - enterprise data management
The PDM system allows all of the product data to be quickly stored, retrieved, displayed,
printed. Managed, and transferred to other parts of the organization.
, When are rapid prototypes useful? - Answers Extremely beneficial when rapid response time is
essential. Rapid prototyping allow designers to generate parts quickly, directly from 3D models,
for mockup and testing.
List three ways a CAD database can be used. - Answers Modeling 2D and 3D geometry to create
drawings that document design for manufacturing, export data to CAE systems for kinematic
analysis.
List five techniques you can use to enhance creativity. - Answers a. Examine manufactured
products
b. Study the natural world
c. Watch the Web
d. Research Patent drawings
e. Design groups
1. Draw the alphabet of lines and label each line. - Answers The instructor should evaluate the
alphabet of lines for neatness, accuracy, and detail drafting techniques. Compare to page 27, fig
2-7.
2. Which architect's scale represents a size ratio of 1:24? Which metric scale represents a half
size? Which engineers' scale would be used for full size? - Answers Architect's scale - ½" = 1'-0"
Metric scale - 1:2
Engineers' scale - the 10th scale
3. What are the main advantages of polyester film as a drawing media? - Answers Available in
rolls and sheets; has very good transparency and printing qualities; is excellent for use with
pencil or ink; erasures are clean and material has high dimensional stability; and resists
cracking, bending, and tearing.
4. What are the four standard types of projections? - Answers Axonometric (Isometric), Oblique,
Perspective, and Orthographic
5. Which drawing lines are thick? Which are thin? Which are very light and should not
reproduce when copied? - Answers Lines that are drawn thick include Visible lines and Cutting
plane lines.
Lines drawn thin are Hidden lines, Dimension lines, Extension lines, Centerlines, and Phantom
lines.
