Symmetry tolerance applied to a plane
To apply the symmetry tolerance to a plane:
Measure four planes, two planes on opposite sides that are
considered to be master surfaces and two planes from surfaces that
are to be symmetrically toleranced (see drawing above). Planes 1
and 2 are measured from master surfaces while planes 3 and 4 are
measured from the surfaces to be symmetrically toleranced.
Construct a reference plane from planes 1 and 2
Construct the plane to be toleranced for symmetry from
planes 3 and 4
Select the resultant plane from the construction using
planes 3 and 4
