Name the practice of locating multiple features used when it is desirable to permit the location of a pattern of features to vary within a larger tolerance than the positional tolerance specified for each feature. For this application, the feature control frame is doubled in height and divided into two parts. Only one positional geometric characteristic symbol is used and it is placed in one double height feature control frame compartment. The upper part of the feature control frame is the pattern-locating control and specifies the larger positional tolerance for the pattern of features as a group. The lower entry is called the feature-relating control and specifies the smaller positional tolerance for the individual features within the pattern. The pattern-locating control locates the
pattern of features as a group to the specified datums. The pattern is located from the datums by basic dimensions. The feature-relating control is a feature-to-feature relationship. The features are related to each other with basic dimensions. The pattern-locating control and feature-relating control are inspected separately but are interrelated. The feature-relating control is free to shift and slant within the boundaries established by the pattern-locating control. When it is desired to control perpendicularity in the feature-relating control, only the primary datum is given in the bottom half of the feature control frame. If no datum reference is provided in the bottom half of the feature control frame, the feature-relating control is free to shift and slant within the boundaries established by the pattern-locating control. The tolerance zone of an individual feature can extend partly beyond the group zone, but the feature axis must fall within the confines of both zones. Also, all of the feature axes must lie within both zones. What will be an ideal response?
