Geometric dimensions appear in a rectangular box called a?

The correct answer is related to the specific format used to convey geometric tolerances in engineering drawings. A feature control frame is a rectangular box that contains geometric tolerances, along with references to datums and specific measurements associated with a feature. This format is critical for ensuring clarity and accuracy in communication regarding the allowable variations in the geometry of parts.

The feature control frame encapsulates key information such as the type of geometric tolerance, the associated datum references, and any applicable limits. This structured presentation allows engineers and manufacturers to interpret the design intent accurately and maintain the required specifications during production and inspection.

In contrast, while other options mention different types of controls or frames, they do not specifically denote the structured framework used for feature tolerance. For instance, a boundary control frame is typically used for defining limits of size rather than geometric characteristics. Thus, the feature control frame is the appropriate term for the geometric dimensions described in this context.
