Dissolving Library Features
After the library feature is inserted into a part, you can dissolve (break down) a library feature into the individual features it contains.
To break down a library feature into the features it contains:
In the FeatureManager design tree, right-click the library feature icon, and select Dissolve Library Feature from the shortcut menu.
The library feature icon is removed, and each of the features it contains is listed individually in the FeatureManager design tree.
