12. True or False? Profile tolerances are always specified with the MMC modifier. 13. True or False? A curved surface must be defined by basic dimensions when a profile tolerance is applied to the surface. 14. True or False? Surface profile may only be used to control the form of a curved surface. 15. True or False? Even when an all around symbol is used, profile tolerances do not extend past abrupt changes in direction. 16. True or False? There is no number shown following the unequally disposed symbol if the entire profile tolerance zone goes inside the material relative to the basic profile of the surface. 17. True or False? When used, unequally disposed profile tolerances must be applied to permit a plus size tolerance rather than a minus size tolerance. 18. True or False? A feature controlled by a profile tolerance may be located by a basic dimension and when basic location dimensions are shown the profile tolerance must include appropriate datum feature references. 19. True or False? A composite profile tolerance may be used to specify a small tolerance for form of a surface and a large tolerance for the form, orientation, and location relative to one or more datums. 20. True or False? One method of specifying coplanarity of multiple flat surfaces is to apply a flatness tolerance. 21. There are at least 22. segments in a composite profile tolerance. profile tolerance may be applied to a surface, but it only controls individual line elements on the surface. 23. Profile tolerances apply along the entire surface to which they are applied, and typically the limits of the surface are defined by direction. 24. In past practices and today as an alternate practice a(n) changes in line is drawn to one side of a feature outline to indicate that a profile tolerance is unilateral. 25. Whether or not. are shown in a feature control frame establishes whether the profile tolerance controls only form or if it controls form, orientation, and location. 26. No. is shown in a profile tolerance specification when controlling form only. _ 27. Dimensions that define the shape of a surface must be ________ if a profile tolerance is applied.
