Tolerancing
Orientation/Angle angles, cones
Angle tolerances can be applied to angles and cones. The tolerance screens are identical, and are used to
specify the acceptable deviation from a nominal angle.
Enter the allowed angle limits into
the Limit data fields as +/- ranges
or as absolute limits. Touch the
Limit data fields to toggle between
+/- ranges or absolute limits.
Orientation/Co-planarity planes
Co-planarity tolerances can be applied to planes and are used to specify
the acceptable deviation from a plane perfectly parallel to a reference
plane.
Touch the Parallelism icon for co-planarity tolerances. Enter the ac-
ceptable co-planarity deviation into the Tol Zone data field, and then
enter the number of the reference feature for the parallelism tolerance
into the Ref Feature data field.
Runout/Circular runout circles, arcs
Circular runout tolerances can be applied to circles and arcs. The tol-
erance screens are identical, and are used to specify the acceptable
deviation from a circle or arc around the center of the reference feature
axis.
Enter the acceptable runout deviation into the Tol Zone data field and
then enter the number of the reference feature for the tolerance into the
Ref Feature data field.
