Why is it useful to break a curved contour into short angular segments during the block-in stage?

Answer and explanation

Correct answer: It makes the proportion of a complex curve easier to measure

The governing concept is construction through observation. A complex curve is difficult to judge as one continuous line, but short angular segments reveal its direction, turning points, height, and width. Comparing these segments with nearby landmarks helps correct proportion before smoothing the contour. Therefore, option D is correct; the other choices concern colour, shadow, or paper and do not explain the block-in method.
