CD Sectional Views & Auxiliary Views

Question 1

What is the primary purpose of a sectional view in technical drawing?

Accepted Answer

To reveal internal features that would otherwise be hidden

Answer

To show the exterior profile of an object

Answer

To replace all orthographic views

Answer

To display surface texture information

Question 2

Which line type represents the cutting plane in a sectional view per ASME standards?

Accepted Answer

A thick alternating long-and-short dash line with arrows indicating the direction of sight

Answer

A thin, solid continuous line

Answer

A medium-weight dashed line

Answer

A long dash–double short dash phantom line

Question 3

In a full section view, how does the cutting plane pass through the object?

Accepted Answer

It passes completely through the object along one axis, exposing the full interior

Answer

It cuts only halfway through the object along the center line

Answer

It bends to pass through multiple offset features

Answer

It revolves around a central feature

Question 4

What is the standard angle for section lines (hatch lines) in a technical drawing per ASME convention?

Accepted Answer

45°

Answer

30°

Answer

60°

Answer

90°

Question 5

In a half-section view, what is shown on each side of the cutting plane line?

Accepted Answer

One half shows the sectioned interior and the other shows the unsectioned exterior

Answer

Both halves show only the exterior

Answer

Both halves show the full interior

Answer

One half is physically removed and only the interior is drawn

Question 6

A broken-out section is best described as:

Accepted Answer

A small portion of an object's interior revealed by an irregular freehand break line

Answer

A section created when drawing paper is physically torn

Answer

A section where the part is completely broken apart and separated

Answer

Multiple disconnected sectional cuts through the same object

Question 7

How is a revolved section created?

Accepted Answer

The cross-section is rotated 90° into the plane of the view and superimposed directly onto the longitudinal view

Answer

The entire object is rotated 90° before the section is taken

Answer

The cutting plane revolves around the object's axis

Answer

The section is created by revolving the object in an isometric projection
