CDT Sectional Views & Auxiliary Views

Question 1

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

Accepted Answer

To reveal interior features by passing a cutting plane through the entire object

Answer

To show the exterior profile of an object

Answer

To display dimensions along the perimeter of a part

Answer

To indicate surface finish requirements on machined faces

Question 2

What do section lines (cross-hatching) indicate in a sectional view?

Accepted Answer

Solid material that has been cut through by the cutting plane

Answer

Areas of the object that are hollow or void

Answer

Surfaces that have been finish-machined

Answer

Hidden features located behind the cut surface

Question 3

In a half-section view, how is the object divided to create the view?

Accepted Answer

Two cutting planes at 90° reveal one quarter in section and show three-quarters as exterior view

Answer

A single cutting plane removes the entire front half of the object

Answer

The object is split along a diagonal to expose interior and exterior simultaneously

Answer

The top half is removed to expose internal features from above

Question 4

What type of line is used to represent the cutting plane on a drawing?

Accepted Answer

A thick chain line (long-short-long dash) with arrows showing the viewing direction

Answer

A thin continuous line with tick marks at intervals

Answer

A dashed hidden line with arrowheads at both ends

Answer

A phantom line with circles at each end indicating the cut path

Question 5

What is the primary purpose of an auxiliary view in engineering drawing?

Accepted Answer

To show the true size and shape of an inclined or oblique surface

Answer

To provide an isometric three-dimensional overview of the part

Answer

To display all hidden lines that cannot appear in the principal views

Answer

To create a scaled-down version of the part for the title block

Question 6

What is a broken-out section?

Accepted Answer

A partial section that uses an irregular break line to locally expose an interior feature

Answer

A section view that has been interrupted with a break line to fit on the sheet

Answer

A section created by breaking the object along its line of symmetry

Answer

A section view that has been removed to a separate detail elsewhere on the sheet

Question 7

Which ANSI/ASME standard governs multiview and sectional view drawings?

Accepted Answer

ANSI/ASME Y14.3

Answer

ANSI/ASME Y14.2

Answer

ANSI/ASME Y14.5

Answer

ANSI/ASME Y14.100
