Add Spec Filter

This option adds the Spec Filter section to your spec. Spec filtering allows you to specify Schedules for particular bore sizes that will apply to the specification. Only the Schedules defined in this filter (if applied to the spec) will be available in the spec sections. This filter can be applied on a Spec wide basis, or applied to individual spec sections.

Reset Filter	Checks and loads any new nominal sizes and clears the current filter values.
Refresh Filter	Checks and loads any new nominal sizes but, unlike the Reset option, keeps the current filter values.
Apply Filter	Enabling this option applies the filter on all of the spec sections. Click it again to remove the filter from the spec sections.
