Which drawing type reveals interior features by cutting completely through the object?

• A. Detail View
• B. Full Section
• C. Broken-Out Section
• D. Half Section

Answer: (B)

When you want to reveal interior features by cutting through the entire part, you use a full section. Imagine slicing the object with a plane that goes all the way through from one side to the other, then removing one half to expose the interior surfaces on the remaining half. This type of view makes hidden features like holes, cavities, grooves, or internal threads easy to see and measure because you’re looking directly at the inside faces as if the part were opened up. How it’s shown in drawings: the plane of the cut is indicated on the exterior view with a cutting-plane line, and the surfaces revealed by the cut are hatched to distinguish the material. Full sections are especially helpful when the interior geometry is complex and would be obscured in a standard external view. Other drawing types show interiors in different ways but don’t cut the whole part. A detail view magnifies a small area for clarity, not an interior cross-section of the entire object. A broken-out section reveals only a portion of the interior, not everything, and a half section shows interior features on one half while the other half remains intact, often used for symmetrical parts.
