Breaking the Link from the Original Part File
You can break the link from the original part file to the inserted part file. By default, when you open a third-party CAD part file, the inserted part file retains the link to the original file.
To break the link from the original part file:
Right-click the top-level part node and click Break Links to break the links for all 3D Interconnect feature links in the part.
This is an irreversible action. After you break the links, you cannot reconnect or update the part with the original part. The Import Feature PropertyManager is also unavailable.
