How many hidden lines are shown in the right side (end) view of the drawing illustrated? GS-0021
Official USCG Answer & Rule Citation
Correct Answer: Option A — None
Hidden lines represent edges or surfaces that are not visible from the current viewing angle. In this specific orthographic projection, the geometry of the object is such that all edges are visible from the right side, resulting in zero hidden lines being required for that view.
