Deck 8: Multiviews

Question 1

List two reasons why views are aligned on a drawing.

Answer 1

Views are aligned to allow the drafter to project points directly from one view to the next in order to establish related features. It makes it easy to extend common dimensions. And it allows the use of a 45° projection line to aid in drawing front, top, and side views, because the depth dimension is the same between the top and side views.

Question 2

Explain in brief statements five basic guidelines to follow when selecting the front view of an object for multiview presentation.

Answer 2

When selecting the front view: 1. The most natural use position 2. Best shape description, or most contours 3. The longest dimension 4. The fewest hidden features 5. The most stable position

Question 3

Why is it not always necessary to select three views to de- scribe an object when using multiview projection?

Answer 3

. Some objects can be completely described with two views or even one view.

Question 4

Show an example of first-angle projection.

Question 5

Describe a chamfer and its use.

Question 6

Give an example of at least three types of objects that can be described with one view.

Question 7

Identify and name the ASME standards that recommend multiview drafting practices.

Question 8

Completely describe the purpose of a removed view and how a removed view is represented on a drawing.

Question 9

Identify the shape of a circular feature when the line of sight, in multiviews, is perpendicular to a circular feature such as a hole.

Question 10

Describe multiview projection.

Question 11

Briefly describe the procedure used to place a removed view on a sheet separate from where the principal view is located.

Question 12

When are one-view drawings practical?

Question 13

What methods are used to space views on a drawing?

Question 14

Show an example of third-angle projection.

Question 15

Completely describe the purpose of a detail view and how it is represented on a drawing.

Question 16

Define orthographic projection.

Question 17

Define true geometry view.

Question 18

Why is it important to prepare a sketch before you begin the actual drawing?

Question 19

Why should caution be used when selecting partial views?

Question 20

When can partial views be used?

Question 21

Describe the shape of a circular feature when a circle is pro- jected onto an inclined surface.

Question 22

Name the type of lines used for the representation of the contour of an object as typically displayed in multiview.

Question 23

What term identifies the intersections of features with cir- cular objects that are projected in multiview to the extent that one shape runs into the other?

Question 24

Briefly describe a fillet and give its basic function.

Question 25

List at least two rules for determining line precedence.
