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

Solid features such as shafts, bolts, nuts, screws, thin ribs, webs, and spokes are conventionally not cross-hatched when the cutting plane passes through them lengthwise, as doing so would be misleading.

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

Adjacent parts in an assembly section must use hatching at different angles or different spacings so each component is clearly distinguishable from its neighbor.

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

Cylindrical parts such as shafts use the 'S-break' (also called the conventional cylindrical break symbol) per ASME Y14.2 to show the part is longer than drawn.

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 fold line represents the edge of the inclined plane as seen in the principal view — the theoretical hinge between the principal projection plane and the auxiliary projection plane.

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

ASME recommends adjusting section line spacing proportionally to the hatched area so the pattern is readable — too dense or too sparse reduces clarity.
