Architect’s scale vs. engineer’s scale – inch divisions An architect’s scale is divided into tenths (0.1) of an inch. Evaluate this statement.

Introduction / Context: Understanding the difference between architect’s and engineer’s scales avoids reading errors on drawings. Architect’s scales use fractional-inch relationships to feet; engineer’s scales use decimal subdivisions of an inch.

Given Data / Assumptions:

• Architect’s scale: common graduations like 1/8 in = 1 ft, 1/4 in = 1 ft, 1/2 in = 1 ft, etc.
• Engineer’s scale: decimal divisions such as 10, 20, 30, 40, 50, 60 divisions per inch.
• Claim states architect’s scale is in tenths of an inch.

Concept / Approach: The statement confuses the two tools. The architect’s scale is not divided in tenths; that is the hallmark of the engineer’s scale. Architect’s scales are arranged to read feet and fractions thereof conveniently from fractional-inch drawings.

Step-by-Step Solution:

Verification / Alternative check: Inspect a physical architect’s and engineer’s scale to see their graduation schemes; all reputable drafting references make this distinction.

Why Other Options Are Wrong: “Correct” would imply architect’s scales are decimalized; they are not.

Common Pitfalls: Using the wrong scale for a given drawing; mixing up imperial fractional and decimal conventions; misreading small graduations.

Final Answer: Incorrect
