Benefit of section views One common outcome of using section views in a technical drawing is the reduction or elimination of hidden lines in the region being sectioned.

Introduction / Context:
Hidden lines indicate edges obscured by geometry. Excess hidden lines can clutter drawings and make interpretation difficult. Section views simplify the display by showing the interior directly, which typically removes the need for hidden lines within the cut zone.

Given Data / Assumptions:

• The cutting plane passes through features previously shown as hidden.
• Drafting standards allow omitting hidden lines within the sectioned area.
• Clarity is the primary objective of the drawing.

Concept / Approach:
By replacing dashed hidden lines with explicit visible edges on the cut face and hatching, the reader can interpret shapes, dimensions, and relationships more rapidly. This increases accuracy in manufacturing and inspection, and reduces misreadings that can occur with dense hidden-line networks.

Step-by-Step Solution:

Verification / Alternative check:
Compare before-and-after readability: the section view should present less visual noise and clearer feature relationships.

Why Other Options Are Wrong:
Limiting the benefit to “castings,” “assembly drawings,” or certain scales is incorrect. The principle applies broadly wherever sections are appropriate.

Common Pitfalls:
Leaving redundant hidden lines inside the sectioned area, over-hatching thin features so they fill in on plots, and selecting a plane that still leaves critical features concealed.

Final Answer:
Correct
