When only a small interior area must be revealed on a drawing, which section method should the drafter use to expose just that localized region? Choose the section type intended for limited, focused interior detail.

Introduction / Context:
Drawings should balance completeness and clarity. If only a tiny internal feature matters, creating a full or half section is excessive. A localized method is preferred to reveal just the needed interior area without cluttering the sheet.

Given Data / Assumptions:

• A small internal zone requires exposure.
• Global sectioning would be overkill.
• Standard drafting conventions apply (hatching, break boundaries).

Concept / Approach:

The broken-out section uses an irregular break line to remove a small surface patch and reveal the interior directly beneath. It is simple to add, does not require a full cutting plane, and focuses attention on the feature of interest.

Step-by-Step Solution:

Verification / Alternative check:

Standards illustrate broken-out sections precisely for cases where a full section would be unnecessary complexity.

Why Other Options Are Wrong:

Half and full: large-scale sectioning, not localized.

Quarter: not a standard term for localized revelation (see quarter section usage below); it indicates removing a fourth of the object, still too extensive for “small area.”

Common Pitfalls:

Making the break boundary too neat; standards allow an irregular freehand look to differentiate it from cut edges.

Final Answer:

broken out
