What is the purpose of an isometric scale?
1.
To lay off intersecting lines
2.
To project the object onto the plane of
projection
3.
To measure foreshortened lines
4.
To measure diagonal lines
6-26.
What is the difference between isometric
drawings and isometric projections?
1.
Lines are drawn foreshortened by two-
thirds
2.
Lines are drawn without the use of a
scale in projections
3.
Lines are drawn without the use of a
scale in drawings
4.
Lines are drawn true length

More accurate
4.
More realistic
6-28.
In an isometric drawing, how should you
place the object on the plane of projection?
1.
With the longest axis vertical
2.
With the longest axis horizontal
3.
With the shortest axis oblique
4.
With the shortest axis parallel to the
longest isometric axis
6-29.
Changing the position of the isometric axes
affects the viewpoint at which the object is
seen.
1. True
2.
False

How do circles appear on isometric planes?
1. As obloids
2. As circles
3. As ellipses
4. As parabolas
6-31.
When transferring noncircular curves from
a multiview drawing to any isometric
drawing, what lines should you use?

multiview drawing
2.
Corresponding nonisometric lines
3.
Corresponding normal lines
4.
Corresponding randomly spaced
parallel lines
6-32.
What feature determines when the
diameters of an ellipse are conjugate?
1.
When the diameter are parallel to the
end tangents
2.
When the diameters are perpendicular
to the end tangents
3.
When the minor diameter intersects the
major diameter at 60°
4.
When the major and minor diameters
are complementary
