CD Sectional Views & Auxiliary Views 3

Question 1

Per ASME standards, which of the following is typically NOT cross-hatched in a section view when cut in its lengthwise direction?

Accepted Answer

Solid shafts, bolts, and thin ribs or webs

Answer

Hollow cylindrical tubes

Answer

Cast housings and brackets

Answer

Welded structural frames

Question 2

When two adjacent parts are shown in an assembly section view, how should their hatch patterns differ?

Accepted Answer

Different angles and/or different spacing to distinguish one component from another

Answer

Same angle and spacing to show they belong to the same assembly

Answer

One part uses section lines and the adjacent part uses dots

Answer

Only one part is cross-hatched; the other uses hidden lines

Question 3

Which conventional break symbol is used to indicate a long uniform cylindrical shaft or rod is shortened on the drawing?

Accepted Answer

An S-break (cylindrical conventional break) symbol

Answer

A dashed line drawn straight across the shaft

Answer

A series of X marks across the cross-section

Answer

A wavy phantom line across the part

Question 4

In auxiliary view projection, the fold line (reference line) between the principal view and the auxiliary view represents:

Accepted Answer

The edge view of the inclined surface — the theoretical hinge between the two projection planes

Answer

The line of intersection between two visible surfaces

Answer

The center line of the auxiliary view

Answer

The boundary of the partial auxiliary view

Question 5

Which statement about section line (hatch) spacing is correct per ASME practice?

Accepted Answer

Section line spacing should be proportional to the size of the hatched area — closer for small areas, wider for large ones

Answer

Section lines must always be exactly 3 mm apart regardless of part size

Answer

Section line spacing is determined solely by the line type selected

Answer

Section lines must always be evenly spaced at a single universal standard

Question 6

A phantom section (ghost section) is used to:

Accepted Answer

Reveal an interior feature on an existing view using section lines drawn in phantom-line pattern without creating a separate cut-away section

Answer

Show a section through a transparent material

Answer

Indicate a section that has been deleted from the drawing

Answer

Show a proposed future feature that does not yet exist

Question 7

When projecting a primary auxiliary view from the front view, from which view are depth measurements transferred?

Accepted Answer

The top or side view — the principal view that shows depth

Answer

The front view itself

Answer

The isometric view

Answer

Any principal view the drafter selects
