How do cross-contour lines give more information than a simple outline?
Answer and explanation
Correct answer: They move across the surface to show volume and curvature
The governing concept is cross-contour drawing, in which lines travel across or around a form rather than merely tracing its outside edge. Their changing direction, spacing, and curvature can describe whether a surface bulges, bends, narrows, or turns in space. On a sphere, for example, curved lines wrapping around the surface help the viewer sense its roundness; on a cylinder, they can indicate the turn of the body. Option A is correct because it identifies volume and surface curvature. B describes an outline, not a cross-contour; C is contradictory because these lines clarify form; and D concerns colour theory rather than structural drawing.
