Have you tried running Part Cleanup?
Typically I would start with checking everything under Moderate Cleanup Actions. If the problem is with the members you might have to recreate them.
No I didin't try part cleanup.
First I CReated one model and making their family. after doing some modification in model I will try to update in part family member but it will throwing error according to attached image. And restricted to crete new part family also.
Hi @BenBroad ,
This is a bug in the NX. If you're able to reproduce it for simple parts , please provide part here or steps so that we can tell you if issue is fixed in later releases.
Else just report it with GTAC.
