GD&T Final questions and correct
answers rated A+

Geometric tolerances are specified on a drawing through the use of a feature control frame. -
correct answer ✔✔ True



The tolerance zone for a flatness tolerance is the space between two perpendicular planes. -
correct answer ✔✔ False



Placing a straightness tolerance on the size dimension of a cylinder overrides rule #1 - correct
answer ✔✔ True



The tangent plane modifier releases the flatness requirement so that portions of the feature's
surface may dip or rise out of the tolerance zone as long as the plane derived by the high points
of the feature's surface stay within the tolerance zone. - correct answer ✔✔ True



The four form tolerances are flatness, straightness, circularity, and cylindricity and they never
require a datum reference in the feature control frame. - correct answer ✔✔ True



True position is defined as the actual dimension that the part measures. - correct answer ✔✔
False



The cylindricity tolerance controls the shape of the feature over the entire length of the feature.
- correct answer ✔✔ True



Zero tolerance at MMC means that no matter what size a holes is drilled, it must be located at
the exact true position dimensions. - correct answer ✔✔ False
