Questions and CORRECT Answers
false - CORRECT ANSWER - The top view of an object shows the height and depth
dimensions.
false - CORRECT ANSWER - If a part is finished all over, it must still have appropriate
finish marks on all surfaces.
false - CORRECT ANSWER - A depth auxiliary view is projected from the right-side
view.
false - CORRECT ANSWER - Parallel lines are never in the same plane.
false - CORRECT ANSWER - The purpose of an auxiliary view is to show the
foreshortened view of a surface.
true - CORRECT ANSWER - There are 3600 seconds in a degree (angle measure).
true - CORRECT ANSWER - There are 3 standard projection planes: frontal, horizontal,
and profile.
true - CORRECT ANSWER - In first angle projection, the object is between the viewer
and projection plane.
false - CORRECT ANSWER - An oblique plane is perpendicular to one of the of the
primary planes.
, false - CORRECT ANSWER - The front view of an object should be chosen to maximize
hidden lines.
false - CORRECT ANSWER - Extension lines may not cross other extension lines.
false - CORRECT ANSWER - The first line of dimensions is usually spaced 3/4" from the
view.
false - CORRECT ANSWER - Reference dimensions may be used for production
purposes.
true - CORRECT ANSWER - A trimetric pictorial has 3 different scales and axes.
true - CORRECT ANSWER - In an isometric drawing, measurements are taken from the
isometric axis at full scale.
false - CORRECT ANSWER - In a cavalier oblique pictorial, the depth dimension is
drawn half-scale.
false - CORRECT ANSWER - A two-point perspective has one vanishing point and one
station point.
true - CORRECT ANSWER - An auxiliary view may be used to find the true length of a
line.
false - CORRECT ANSWER - If a surface is perpendicular to a primary plane but not
parallel to any of the primary planes, a secondary auxiliary view must be constructed to find its
true shape.
true - CORRECT ANSWER - The reference plane/fold line must be constructed parallel to
the edge view of a surface to construct the true size and shape of the surface.
