Chapter 3: 13. What type of geometric tolerance has no datum features? 14. A theoretically exact dimension is called a 15. The feature symbol specifies that a group of two or more interrupted features of size are to be considered one single feature of size. 16. For an individual regular feature of size, no element of the feature shall extend beyond the maximum material condition boundary (envelope) of perfect form. This statement is the essence of 17. What is the name of the symbol used to identify physical features of a part as a datum feature and must not be applied to centerlines, center planes, or axes? 18. The is the condition in which a feature of size contains the maximum amount of material within the stated limits of size. 19. The total positional tolerance equals the sum of the tolerance and the tolerance.
