When is a hard edge suitable in form?
Answer and explanation
Correct answer: When a plane change or sharp corner must be shown
The governing concept is the use of edge hardness to describe structure. A hard edge gives a clear visual boundary where two planes meet, where a corner changes direction, or where a geometric surface must appear crisp. Option A is correct because a plane change or sharp corner needs that definite transition, as in a cube, box, or architectural form. A sphere that is meant to look completely smooth generally uses softer transitions, so B is unsuitable. Removing a shadow, as stated in C, is not the purpose of a hard edge; shadows are controlled by the light source and tonal values. Option D is unrelated because a drawing cannot make a visual form into sound.
