Drawing scale: “Drawing scale refers only to reducing the drawn size relative to the real object.” Evaluate this claim about scale usage in technical drawings.

Difficulty: Easy

Correct Answer: Incorrect

Explanation:


Introduction / Context:
Scale expresses the ratio between the size on paper and the actual object. While many engineering drawings reduce large objects to fit a sheet, scale is a general concept that also supports full-size and enlarged views.


Given Data / Assumptions:

  • Common scales: full size (1:1), reductions (e.g., 1:2, 1:10), and enlargements (e.g., 2:1, 10:1).
  • Choice of scale depends on detail clarity and sheet constraints.
  • The statement claims scale refers only to reduction.


Concept / Approach:
Scale is a proportional mapping. Nothing about the definition excludes enlargements; small parts often need enlargement to show fine features or tolerances clearly.


Step-by-Step Solution:
Identify three categories of scale: 1:1, x:1 (enlarged), and 1:x (reduced).Recognize typical use cases: site plans are reduced; micro-components are enlarged.Therefore, limiting scale to reduction alone is incorrect.


Verification / Alternative check:
Standards list multiple standard metric and imperial scales including enlargements; title blocks specify the chosen scale.


Why Other Options Are Wrong:
“Correct” misstates the concept. Restricting to certain disciplines or sheet size is misleading; scale selection is universal and driven by clarity.


Common Pitfalls:
Using too small a reduction that hides details; failing to break out enlarged detail views when needed.


Final Answer:
Incorrect
