Why can contour lines be used in form drawing?
Answer and explanation
Correct answer: To explain surface direction and volume
The governing concept is that contour lines describe the way a surface turns around or across a form. An outer contour defines the boundary, while an inner or cross-contour follows the surface and helps the viewer understand its direction, curvature, and volume. For example, curved lines across a cylinder suggest that the surface wraps around it rather than remaining flat. Therefore, option A is correct. Paper smell, sound, and erasing are unrelated to visual structure. Contour lines may be used without heavy shading, but they still communicate the three-dimensional organisation of the form.
