1. The views that show what an object’s projection looks like when seen from the top, the front,
and the side are known as
a. isometric views.
b. orthographic views.
c. standard views.
d. normal views.
Analysis:
2. Which three views are most commonly used to describe most objects?
a. top, front, and back
b. front, bottom, and left
c. top, back, and right
d. top, front, and right
Analysis:
3. Hidden lines are used to show
a. the intersection of two planes that are not visible from the direction you are looking.
b. reference locations for the machinist who will be making the part.
c. optional start/stop locations.
d. reference locations for assembly.
Analysis:
4. Solid lines are used to show
a. reference locations for the machinist who will be making the part.
b. the visible edges of planes or the intersection of two planes.
c. optional start/stop locations.
d. reference locations for assembly.
Analysis:
5. Center lines, or lines of symmetry, are used to show
a. reference locations for the machinist who will be making the part.
b. the visible edges of planes or the intersection of two planes.
c. reference locations for assembly.
d. where the center of holes or the center of cylinders are.
Analysis:
6. The number of orthographic views that you should draw to represent an object
a. is always three.
b. is at least three.
c. is at most three.
d. depends on the complexity of the object.
7. Engineering drawings provide information about
a. size, shape, and material of a product.
b. dimensions and tolerances.
c. surface finish and part number(s).
d. all of the above
Analysis:
8. There are basically two concepts that you need to keep in mind when specifying dimensions in
an engineering drawing:
a. size and location.
b. size and material.
c. size and tolerance.
d. part number and material.
Analysis:
9. An engineering drawing is dimensioned with the aid of
a. dimension lines.
b. extension lines.
c. centerlines and leaders.
d. all of the above

Analysis:
10. The lines that provide information on the size of the object – for example, how wide it is and
how long it is, are known as
a. dimension lines.
b. extension lines.
c. leaders.
d. none of the above
Analysis:
11. The lines that extend from the points to which the dimension or location is to be specified are
known as
a. dimension lines.
b. extension lines.
c. leaders.
d. none of the above
15. The view that shows the solid portions and the voids within the object are known as
a. isometric view.
b. orthographic view.
c. standard view.
d. sectional view.
Analysis:
16. In a sectional view, the solid portion of the view is marked with
a. cross-hatching.
b. shading.
c. hidden lines.
d. rendering.
Analysis:
17. Which of the following are components of a sectional view?

d. all of the above
Analysis:
18. AutoCAD, IDEAS, and Pro-E are examples of
a. solid modeling software.
b. civil engineering drawings.
c. electrical drawings.
d. electronic drawings.
Analysis:
19. CNC machines are often used to make parts directly from solid modeling software. What
does CNC stand for?
a. central navigation center
b. computer navigation center
c. computer nominally controlled
d. computer numerically controlled
20. A “language” used by engineers to convey their ideas, their solutions to problems, or
analyses of certain situations is known as
a. drawings.
b. symbols.
c. calculations.
