Which statement correctly describes the information conveyed by a feature control frame?

• A. The geometric tolerance, the datum references, and any modifiers for a feature.
• B. The material requirement only.
• C. The color specification.
• D. The surface texture symbol.

Answer: (A)

A feature control frame tells you how a geometric tolerance is applied to a feature. It communicates the type of tolerance (the geometric characteristic), the size of the tolerance zone (the numeric tolerance, sometimes with a diameter symbol), the datum references that establish the datum reference frame, and any modifiers that affect how the tolerance is interpreted (such as MMC/LMC or a projected tolerance zone). This combination defines what variation is acceptable and exactly what references are used to measure against. Material requirements, color specifications, and surface texture symbols are not conveyed by the frame itself. Material condition modifiers can appear in the frame, but the frame does not specify color or general material requirements; those are covered by separate notes or callouts.
