GD&T Angularity Tolerance
Angularity is the condition where a surface, axis, or center plane is at the specified
angle to a datum plane or datum axis.
An angularity tolerance is a geometric toleranc
GD& T Training Lesson 8 Circularity
The definition of circularity has two parts. The first part applies to features other than a
sphere; the second applies to spherical features.
For a feature, othe
GD& T Training Lesson 7 Straightness
An axis is a straight line that passes through the center of the actual mating envelope.
A derived median line is established from the actual part feature.
A de
GD& T Training Lesson 9 Cylindricity
Cylindricity is the condition of a surface of revolution in which all points of the surface
are equidistant from a common axis.
A cylindricity tolerance is a geo

Coordinate Tolerancing and GD & T
Coordinate tolerancing is a dimensioning system where a part feature is located (or
defined) by means of rectangular dimensions with given tolerances.
It does a goo

GD& T Training Lesson 10 Planar Datums
The datum system is a set of symbols and rules about how to constrain a part to establish
a relationship between the part and geometric tolerance zones.
