Cutting plane line display If a cutting plane line would obscure important details in a view, it is acceptable to show only the ends of the line outside the view along with the directional arrows.

Introduction / Context:
Cutting plane lines indicate where a section is taken and in which direction it is viewed. However, drawing clarity is paramount. Standards allow modifications to the display of cutting plane lines when a full-width line would clutter the view or mask critical geometry.

Given Data / Assumptions:

• A cutting plane passes through regions dense with geometry or annotation.
• Showing the full line would degrade readability.
• The section arrows and identifiers must remain clear and unambiguous.

Concept / Approach:
To preserve clarity, you may break or abbreviate the cutting plane indication: show just short segments (tabs) of the cutting plane line outside the affected view edges, along with arrowheads and labels (e.g., A–A). This keeps the reader informed about the section location and direction without obscuring details in the parent view.

Step-by-Step Solution:

Verification / Alternative check:
Confirm with applicable company or project standards; many drafting guides explicitly show examples of broken or partial cutting plane lines for clarity.

Why Other Options Are Wrong:
“Incorrect” ignores widely accepted clarity-driven exceptions. Restrictions like “only in auxiliary views,” “only for assembly sections,” or “only at 1:1 scale” are not standards-based rules.

Common Pitfalls:
Removing too much so the section becomes ambiguous; failing to keep arrow direction consistent with the created section view; mismatched section labels.

Final Answer:
Correct
