Thank you for all the informative videos for us NX newbies. I noticed there was no explanation of "Allow Multiple Values" for the attribute settings. Could you point to a source that would give an example use case?
Yes, it's possible with a little bridge. You select an object or feature, select properties, create a title and a Value. Then you select the part in the Assembly Navigator, click on properties, create a Title and select the option Expression Formular. Open the pull-down-menu and select Reference, Object Attribute... Then select your Feature or Object. They are now connected.
