Bi-directional tolerance (circles, points, arcs, spheres)
Use bi-directional tolerance to specify nominal position and size for a selected
feature, specify upper and lower deviation allowed from nominal position and
size, and calculate pass/fail results. Bi-directional tolerance compares the mea-
sured location of a center point (on at least one axis) to the nominal location of
that feature's center point.
To perform a bi-directional tolerance
Step 1
Highlight the desired feature in the features list.
NOTE
Use only a circle, point, arc, or sphere. Bi-directional tolerances
do not apply to other types of features.
Step 2
Click the bi-directional button on the tolerance toolbar.
Step 3
Type the nominal X and Y values for your part in the boxes as shown.
