Question 3

When a circularity tolerance is applied to a cylindrical surface, the circularity tolerance does not override Rule #1.

Answer 3

True

Question 4

When a circularity tolerance is applied to circular elements of a cylinder, the circularity deviation is verified by finding the distance between two ____________________ circles that all of the points of the surface are located between.
