Deck 6: Reading Auxiliary Views

Question 1

When a surface feature is perpendicular to the line of sight, the feature is said to be foreshortened, or shorter than true length.

Answer 1

FALSE

Question 2

The preferred practice is to align an auxiliary view with its principal view when possible, which generally makes it easier to read the print. However, there is an option to rotate an auxiliary view when the normal auxiliary view placement takes up too much space on the sheet. When this is done, a viewing-plane line is used to indicate from where the view is taken, and the auxiliary view is placed in any desired location on the sheet. The auxiliary view is rotated as needed and the angle and direction of rotation is specified under the view title.

Answer 2

TRUE

Question 3

When it is not possible to align the auxiliary view directly from the inclined surface, then a viewing-plane line can be used and the view placed in a convenient location on the sheet.

Answer 3

TRUE

Question 4

The viewing-plane line is labeled with numbers so the view can be clearly identified. This is especially important to observe when several viewing-plane lines are used to label different auxiliary views.

Question 5

Primary auxiliary views are views that take the place of a principal view.

Question 6

The full auxiliary view shows the true size and shape of the inclined surface.

Question 7

The partial auxiliary view shows only the true size and shape of the inclined surface.

Question 8

When multiple auxiliary views are shown on the print, the views are arranged from left to right and from top to bottom. The views are labeled to correlate with their viewing plane, such as VIEW A-A for the first view, VIEW B-B for the second view, and VIEW C-C for the third view.

Question 9

An auxiliary view is projected from the inclined surface in the view where the inclined surface appears as a:

A) contour
B) surface
C) partial view
D) line or edge
E) none of the above

Question 10

The removed auxiliary views are placed in the same relationship as the viewing-plane lines read, and as if the auxiliary view were projected directly from the slanted surface.

Question 11

When a surface feature is not perpendicular to the line of sight, the feature is said to be:

A) parallel
B) foreshortened
C) at right angles
D) True length
E) none of the above

Question 12

These views allow you to look directly at the inclined surface:

A) Auxiliary views
B) Sectional view
C) Front view
D) Side view
E) none of the above

Question 13

These views are used to show the true size and shape of a surface that is not parallel to any of the six principal views.

A) Auxiliary views
B) Sectional view
C) Front view
D) Side view
E) none of the above

Question 14

When necessary, auxiliary views can be found on a sheet other than where the viewing plane lines appear. The method for doing this is called cross-reference zoning and is used to indicate the location of a view back to the viewing location on a previous page. The auxiliary view is located on a different page and is labeled with the sheet number and zone of the cross-reference viewing plane.

Question 15

The auxiliary view can then be drawn in any convenient location at any desired scale.

Question 16

An auxiliary view allows you to look directly at the inclined surface.

Question 17

A secondary auxiliary view is projected from a primary auxiliary view. The definition of secondary auxiliary view is a view that is adjacent to and projected from a primary auxiliary view or from another secondary auxiliary view.

Question 18

When the auxiliary view is completed, one projection line remains between the views to indicate alignment and view relationship.

Question 19

Auxiliary views are used to show the true size and shape of a surface that is not parallel to any of the six principal views.

Question 20

When the reference arrow method is used, a viewing arrow with a view identification letter points to the location from where the view is taken. The auxiliary view is then placed in any desired location on the sheet and in the same orientation as the reference arrow. The view identification letter is placed above the auxiliary view.

Question 21

Describe an optional reference arrow method used to show a removed auxiliary view that was introduced into ASME Y14.3 by the International Organization for Standardization (ISO).

Question 22

Briefly define auxiliary views.

Question 23

What is it called when a surface feature is not perpendicular to the line of sight?

Question 24

This shows the true size and shape of the inclined surface and all other features of the object projected onto the auxiliary plane.

A) full
B) secondary
C) partial
D) incomplete
E) none of the above

Question 25

Describe the use of a removed auxiliary view application.

Question 26

Define secondary auxiliary view.

Question 27

Describe the method called cross-reference zoning used to indicate the location of a view back to the viewing location on a previous page.

Question 28

This is a view that is adjacent to and projected from a primary auxiliary view or from another secondary auxiliary view.

A) full
B) secondary
C) partial
D) incomplete
E) none of the above

Question 29

Describe the use of an auxiliary view enlargement application.

Question 30

Name the method used when a viewing arrow with a view identification letter points to the location from where the view is taken. The auxiliary view is then placed in any desired location on the sheet and in the same orientation as the reference arrow. The view identification letter is placed above the auxiliary view.

A) orientation arrow method
B) location arrow method
C) position arrow method
D) reference arrow method
E) none of the above

Question 31

This auxiliary view shows only the true size and shape of the inclined surface.

A) full
B) surface
C) partial
D) incomplete
E) none of the above

Question 32

Briefly explain the difference between the partial auxiliary view and the full auxiliary view.
