Baseline dimensioning correct answers when each dimension originates from a common point,
line, plane, or axis. The possibility of tolerance buildup arises when using baseline dimensioning
is less likely to occur than to when using chain dimensioning.
Actual Mating Size correct answers is the smallest distance between two parallel planes within
which the actual surface features are contained.
Feature of size correct answers is a set of two opposed elements or opposed parallel planes
surfaces, each of which is associated with a size dimension.
Actual local size correct answers is any cross sectional measurement at any two adjacent points.
Nominal size correct answers is a dimension used for general identification such as stock size or
thread diameter.
Actual size correct answers is the term of a measured size of a part after manufacturing
Chain dimensioning correct answers is placing one after the other from one feature to the next
across the part.
I, O, Q. correct answers Any letters can be used for datum points except for
Specific Datum and Target Number correct answers are located in the lower half of a datum
target symbol.

The target area size correct answers is located in the top half of a datum target symbol
planes, points, lines, axis, or a combination thereof correct answers Datums are ...
Theoretical datum feature simulator: correct answers Perfect boundary used to establish a datum
from a specified datum feature.
Physical datum feature simulator: correct answers A physical boundary use to establish the
simulated datum from the specified datum feature.

Circularity Geometric Tolerance correct answers single cross sectional tolerance representing a
zone between two concentric circles.
Cylindricity Geometric tolerances correct answers covers both circular and longitudinal elements
at the same time representing a zone between two concentric circles.
