Revolved section presentation: May the visible lines adjacent to a revolved section be broken out to improve clarity if desired?

Introduction / Context:
A revolved section shows the cross-sectional shape of a part taken at a specific location and rotated into the plane of the view, often directly on the view of a long member like a spoke, rib, or beam. Because the added sectional outline can crowd existing visible edges, drafters use conventions to keep the graphic clear.

Given Data / Assumptions:

• We are dealing with an in-place revolved section (the section is drawn on the view).
• Adjacent visible lines may coincide with or clutter the revolved profile.
• Standards allow limited modification for legibility.

Concept / Approach:
Clarity is a prime drafting objective. When a revolved section is superimposed on an existing view, breaking out or interrupting nearby visible lines prevents the revolved profile and object edges from merging into an unreadable cluster. This is acceptable practice provided the break is obvious, consistent, and does not remove necessary geometry information elsewhere.

Step-by-Step Solution:

Verification / Alternative check:
Compare two versions of a shaft-with-keyway revolved section: the version with a small breakout around the section reads faster and reduces the risk of mistaking boundaries or hatch for object edges.

Why Other Options Are Wrong:

Common Pitfalls:
Over-breaking lines and losing context; failing to annotate the section location clearly; drawing hatch too dense so it overwhelms the view.

Final Answer:
