I am facing this issue in Creo 2. I have a copied feature in my model and it is named . However its name will be changed back to default each time i redefine the earlier features. How to avoid this? I attached my file here for you reference. Thanks.
I think it is probably because of the dependent copy. Be careful with these because if you want to change anything it will populate to the other models. I tend to un-tick dependent copy.
Thanks, I filed a case with PTC and got the reply saying this is a bug.
