Chapter 6 -- Auxiliary Views
What three purposes does an auxiliary view serve?
-- it illustrates the true size of a surface -- it illustrates the true shape of a surface, including all true angles and/or arcs. -- it is used to project and complete other views
Which of the following is not a purpose that an auxiliary view serves? a. To avoid having to create a removed sectional view b. To illustrate the true size of a surface c. To illustrate the true shape of a surface d. To project and complete other views
A
Explain the use of a reference line. Where should it be drawn, and at what angle?
A reference line, which is also the edge view of a reference plane, should be constructed in the right-side view. It should always be vertical and pass through as many points as possible, and should be drawn at a 90 degree angle.
Explain the use of a secondary auxiliary view.
A secondary auxiliary view is projected directly from the auxiliary view. This view is used when the primary auxiliary view is not enough to fully illustrate an object.
What is an auxiliary sectional view?
An auxiliary sectional view in section.
Which of the following is not true regarding and auxiliary sectional view? a. It is an auxiliary view in sections. b. It is drawn exactly as is any removed section view. c. Generally, only the surface cut by the cutting-plane line is drawn. d. Not all of the auxiliary view rules apply.
B
When we draw an auxiliary view, projection lines must be drawn at what angle from the inclined surface? a. 60 deg b. 45 deg c. 90 deg d. none of the above
C
Which of the following is not true regarding a secondary auxiliary view? a. It is projected directly from the auxiliary view b. Many times the secondary auxiliary view is completed after the primary auxiliary view. c. A secondary auxiliary view is always created. d. None of the above
C
Which of the following is not a major kind of auxiliary view? a. Front view b. Top view c. Side view d. Bottom view
D
A primary auxiliary view is always projected from the front view. T/F?
F
A reference line should be drawn horizontally and pass through as many points as possible. T/F?
F
Use of the half auxiliary view is very common because it saves time. T/F?
F
Name the three major kinds of auxiliary view.
Front Auxiliary View, Top Auxiliary View, Side Auxiliary View
What is the practice for the use of hidden lines in an auxiliary view?
Hidden lines should be omitted in an auxiliary view, unless they are needed for clarity.
Explain the use of partial views as used in conjunction with an auxiliary view.
Partial views as used in conjunction with an auxiliary view make it possible to eliminate one or more of the regular views which, in turn, saves drafting time and cost.
How should the regular views and the auxiliary view be placed within the work area?
Placed so that the auxiliary view is projected 90 degrees from the inclined surface of the regular view.
Projection lines must be drawn at what angle from the edge view?
Projection lines must be drawn at an 90 degree angle from the edge view.
A partial auxiliary view makes it possible to eliminate one or more of the regular views. T/F?
T
Hidden lines in an auxiliary view should be omitted unless they are needed for clarity. T/F?
T
Only the inclined surface is projected into the auxiliary view. T/F?
T
When and why is a half auxiliary view used?
Used to eliminate one or more of the regular views.
