In composite drawings, each ply must be specified by:
A{'text': 'Only material type', 'label': 'A'}
B{'text': 'Material + ply ORIENTATION + position in stack + boundaries (cutouts, joins)', 'label': 'B'}
C{'text': 'Only thickness', 'label': 'C'}
D{'text': 'Only fiber type', 'label': 'D'}
Answer & Solution
Correct answer: B. {'text': 'Material + ply ORIENTATION + position in stack + boundaries (cutouts, joins)', 'label': 'B'}
Composite drawings are not "thickness specs" like metal sheet — they're ply-by-ply stack maps. Each ply needs its angle (0°, 90°, ±45°, etc.), its position in the stacking sequence, and the boundary of its area.
