Difficulty: Easy
Correct Answer: quarter
Explanation:
Introduction / Context:
Different section types remove different proportions of the object to show interior details while maintaining exterior context. Knowing the correct names helps ensure consistent communication on drawings and in design reviews.
Given Data / Assumptions:
Concept / Approach:
A quarter section removes one fourth of the object so that two adjacent orthogonal planes effectively expose interior details while retaining substantial exterior reference. While less common than half sections, quarter sections are used when symmetry and feature distribution make a one-fourth removal optimal.
Step-by-Step Solution:
Verification / Alternative check:
Drawing references recognize quarter sections (alongside full and half) for special cases, especially where dual symmetry planes exist.
Why Other Options Are Wrong:
Full: implies cutting completely through the object.
Half: implies removing one half (a quarter of the 3D solid is actually removed in a typical half section view, but the drawing term “half section” refers to half the view in section; here the question explicitly states one fourth removed, matching “quarter”).
None of the above: incorrect because “quarter” exists as a named method.
Common Pitfalls:
Confusing the fraction removed in 3D with the fraction of the 2D view hatched; rely on the terminology provided by the standards in the problem.
Final Answer:
quarter
