How to show contact with the Cutting Plane in a section view In a sectional drawing, how are the areas that the Cutting Plane passes through and would contact in solid material depicted?

Introduction / Context:
Section views communicate which parts of an object are solid where the imaginary cut occurs. This is achieved visually by a standardized hatching technique, differentiating cut regions from open cavities or holes.

Given Data / Assumptions:

• The Cutting Plane intersects solid regions of the component.
• Standard hatch conventions (angle, spacing) are followed.
• Holes and voids remain unhatched.

Concept / Approach:
Section lining (hatching) fills just those areas where the plane intersects solid material. The hatch conveys continuity of material and, with pattern choice, sometimes the material class. It also helps the viewer distinguish between bounding edges and interior solids.

Step-by-Step Solution:
Establish the Cutting Plane location and direction.Project the resulting section outline.Apply uniform hatch lines to regions of solid material cut by the plane.Leave holes/voids unhatched; keep hatch spacing consistent.

Verification / Alternative check:
Standards specify angles (often 45 degrees) and spacing for general hatching, with variations for different materials. Correct use prevents misreading voids as solids.

Why Other Options Are Wrong:

• Cutting plane line: marks the slice location on the parent view, not the cut areas.
• Visible lines: outline geometry but do not indicate cut material.
• Lines and arrows: describe direction of sight only.

Common Pitfalls:
Hatching across thin webs/ribs against standards, inconsistent spacing, or hatching through fasteners that should be unsectioned.

Final Answer:
Section lining
