Cutting Plane line style: The preferred representation uses a distinctive heavy line with alternating long and short dashes (or a standard cutting-plane symbol) and arrowheads; it is not made of equal dashes only.

Introduction / Context:
The Cutting Plane line must be immediately recognizable among other line types so that readers can locate the imaginary cut and its viewing direction. Standards specify characteristic patterns and arrowheads for this purpose.

Given Data / Assumptions:

• Cutting Plane lines are thick and end with arrowheads indicating the direction of sight to the sectional view.
• Common standards call for alternating long and short dashes, or a specialized cutting-plane symbol, not uniformly equal dashes.
• The statement claims the preferred style uses equal dashes only.

Concept / Approach:
Visual differentiation is critical; making the pattern distinct from hidden lines (short dashes) and centerlines (alternating long and short with thinner weight) prevents confusion. The heavy, long-short pattern plus arrowheads achieves this clarity better than equal-dash sequences.

Step-by-Step Solution:
Identify the correct pattern: heavy weight, long-short dashing (or equivalent standard symbol).Confirm presence of labeled arrows (e.g., A–A).Compare with the claim of equal dashes only.Conclude the claim is incorrect.

Verification / Alternative check:
Consult any drafting line-type chart: Cutting Plane lines are pictured with heavy weight and distinctive patterns and arrows that are not simply equal-length dashes.

Why Other Options Are Wrong:
“Correct” conflicts with common standards. Limiting correctness to schematics, tying it to paper size, or to the presence of hidden lines does not change the required pattern.

Common Pitfalls:
Using centerline or hidden-line styles by mistake; forgetting arrowheads or labels; drawing the line too light to stand out.

Final Answer:
Incorrect
