ADDA Mechanical Drafter Certification
Practice Exam - Part III
False - Answer The top view of an object displays its height and depth
dimensions.
False - Answer Even if a part is finished, it must have proper finish marks on all
surfaces.
False - Answer The depth auxiliary view is projected from the right-side view.
False - Answer Parallel lines never share the same plane.
False - Answer An auxiliary view is used to offer a foreshortened view of a
surface.
True - ANSWER A degree (angle measure) contains 3600 seconds.
True - ANSWER There are three standard projection planes: frontal, horizontal,
and profile.
True - ANSWER In first angle projection, the item is located between the
spectator and the projection plane.
False - Answer Oblique planes are perpendicular to one of the major planes.
False - Answer To increase hidden lines, select an object's front view.
False - Answer Extension lines must not intersect other extension lines.
False - Answer The first line of dimensions is typically 3/4" from the view.
, False - Answer Reference dimensions may be utilized in production.
True - ANSWER A trimetric pictorial contains three separate scales and axes.
True - ANSWER In an isometric drawing, measurements are taken at full scale
along the isometric axis.
False - Answer In a cavalier oblique pictorial, the depth dimension is
represented at half-scale.
False - Answer A two-point perspective consists of one vanishing point and one
station point.
True - ANSWER An auxiliary view can be used to determine the true length of
a line.
False - Answer If a surface is perpendicular to a primary plane but not parallel
to any of the primary planes, a secondary auxiliary perspective is required to
determine its true shape.
True - ANSWER To determine the true size and shape of a surface, the
reference plane/fold line must be established parallel to the edge view.
False - Answer Pictorial drawings typically feature hidden lines.
