---------------
You may have the case where you have a large number of part family member parts but for whatever reason do not have access to the Part Family template that created it. These parts are considered to be "orphans" since their parent file is missing. You need to remove the read-only flag from them in order to import these into Teamcenter, but there is no way to remove this flag interactively in NX.
Solution
The NX utility
ug_edit_part_names will allow the flag to be removed. To run the utility perform the following steps:
o Launch an NX Command Prompt window
Start --> Siemens NX --> NX Command Prompt
o ug_edit_part_names yourfilename.prt -o yourfilename.prt
The above command will process your file and keep the name the same. When the file is now opened it will no longer be flagged as a Part Family member with a read-only status.
