Introduction / Context:
A sectional view must clearly reference where the cut was taken. The Cutting Plane line provides this reference on a related orthographic view. Drawings are commonly arranged so that the parent view containing the Cutting Plane line is near (often adjacent to) the resulting sectional view to make cross-referencing simple.
Given Data / Assumptions:
- Section views are labeled to match Cutting Plane labels (e.g., Section B–B).
- Good sheet layout places related views close together for readability.
- Arrows on the Cutting Plane show view direction; the section’s orientation matches those arrows.
Concept / Approach:
The Cutting Plane line belongs on the view from which you take the cut—commonly an adjacent principal view. Proximity minimizes eye travel and reduces errors when correlating internal features to the source geometry. While “adjacent” is a layout guideline rather than a strict rule, it describes typical best practice accurately.
Step-by-Step Solution:
Place the Cutting Plane line on the appropriate parent view (front, top, or side).Add arrowheads indicating direction of sight for the section.Label the line (e.g., C–C) and label the derived section accordingly.Arrange the sectional view close to the parent view to aid quick interpretation.
Verification / Alternative check:
Check the sheet: if a reader can easily find the cutting reference when viewing the section, the layout follows standard practice.
Why Other Options Are Wrong:
Incorrect: The cutting location should be explicitly shown; stating otherwise undermines clarity.Shown only on auxiliary views / only in notes: The line must appear graphically on the actual parent view, not just in text or only on auxiliary views.
Common Pitfalls:
Placing the section view far from the parent view, forcing long cross-referencing.Forgetting to match labels between the Cutting Plane and the section view.
Final Answer:
Correct
