  drawn of an object is 8.
 False
 The correct number is 6.

   type of plane? ___________________
                   inclined
Orthographic Projections

 True/ False:

 The bottom view usually shows the most
  hidden features.
 False
 The bottom view will not
  necessarily have anything
  hidden. It just depends on the
  object and the number of views
  necessary to describe it.
Orthographic Projections

 True/ False:

 If possible in a multiview drawing, all
    surfaces should be shown true size.
 True
Orthographic Projections

 True/ False:

 First-angle projection is the principal
   multiview projection used in the United
   States.
 False
 Third-angle projection is the
   projection style used in the U.S.
Orthographic Projections

 True/ False:

 In an orthographic view, some planes may
   be foreshortened.
 True
Orthographic Projections

 True/ False:

 A first-angle projection show the front view,
   the right side view, and the top view.
 False
 First angle projection shows the
   top view, front view and left side
   view.
Orthographic Projections

 True/ False:

 Construction lines are vital when drafting
  manually, but unnecessary when using a
  CADD system.
 False
 Construction lines are vital either
  way.
Orthographic Projections

 True/ False:

 The front view should have the most
  hidden lines.
 False
 The front view should have the
  least number of hidden lines.
Orthographic Projections

 True/ False:

 It is possible to have a drawing of an object
    with only one view.
  True
Orthographic Projections
 True/ False:

 Always use three views to adequately
   describe an object.
 False
 Three views are not always
   enough to describe an object.
   Sometimes an object only needs
   one or two views and other times
   it may need all six views.
Orthographic Projections

 True/ False:

 Orthographic Projection is one method to
  create a multiview drawing.
 True
Orthographic Projections

 True/ False:

 A hidden line precedes a center line.
 True
Orthographic Projections

 True/ False:

 A multiview drawing represents the shape
   of an object using two or more views.
 True
Orthographic Projections

 True/ False:

 When possible, a multiview should show
  the surface of the object in its true size
  and shape.
 True
Orthographic Projections
 The most natural position of use ____.
 a. is one of the criteria used for choosing a
    front view
 b. should be the right side view
 c. should be shown with a view
    enlargement
 d. is the common multiview orientation
 e. none of the above
Orthographic Projections
 If a centerline, a hidden line, and an object
     line all occur at the same space in a
     multiview drawing, which line takes
     precedence?
 a. centerline
 b. hidden line
 c. object line
 d. cutting plane line
 e. not enough information to assess an
     answer
Orthographic Projections

 True/ False:

 A multiview drawing represents the shape
   of an object using two or more views.
 True
Orthographic Projections
 True/ False:

 The front view should always have the longest
   dimensions.
 False
 The longest dimensions is only one of the
   rules for picking the front view. If the view
   has the most hidden lines and does not
   show the shape the best, then the fact that
   it has the longest dimensions does not
   qualify it for the front view.

 The result of a multiview projection is a
  multiview drawing.
 True
Orthographic Projections

 True/ False:

 Hidden lines are needed whenever
   there is something hidden in a
   view, regardless of projection
   style.

 The front view is usually the most important
  view.
 True
Orthographic Projections

 True/ False:

 Third angle projection is the type used in
  the United States.
 True
