Updating a Shrinkwrap Feature
When you redefine the Shrinkwrap feature, it is automatically recreated, reflecting the changes in the reference model. During the re-creation process the options that affect the external surface collection (quality level, include/exclude quilts, hole filling, ignore small surfaces, component subset, and subset options) are analyzed. Surfaces that are removed as a result of component addition or removal are deleted from the feature. Consequently some Shrinkwrap feature children may fail.
When the Shrinkwrap feature is defined as independent or when reference models are unavailable (not in session or unavailable in the current simplified representation), such references are frozen.
