Difficulty: Easy
Correct Answer: Incorrect
Explanation:
Introduction / Context:
Offset sections allow one sectional view to pass through multiple, non-collinear features by bending the cutting plane in the parent view. This technique captures a comprehensive interior profile without multiple separate sections.
Given Data / Assumptions:
Concept / Approach:
Depicting the bends in the section view would clutter the drawing and miscommunicate geometry. The purpose of the offset is to synthesize a flat depiction of several features aligned in one view. The only place to show the “bent” path is the Cutting Plane line on the parent view.
Step-by-Step Solution:
Locate offset bends in the Cutting Plane line on the parent view (with arrows and labels).Generate the sectional view by projecting features along the stepped path but presenting the final profile as one coherent, flat section.Compare with the claim that bends appear in the section view.Conclude the claim is incorrect.
Verification / Alternative check:
Textbook figures of offset sections consistently show a smooth, continuous hatch boundary in the section view with no kink lines, while the parent view’s Cutting Plane line displays the offsets.
Why Other Options Are Wrong:
“Correct” reverses the standard convention. Projection method and hatch angle do not change the rule. Auxiliary views are separate constructs and do not necessitate showing the bends in the section view.
Common Pitfalls:
Accidentally drawing the jog lines in the section; forgetting to make the Cutting Plane line heavy and labeled so readers understand the offsets.
Final Answer:
Incorrect
