SW2014 I have a few parts mated and saved in an assembly. When I click on a part and add features, or modify, then save, it does not change the part file.
If I go to the part file, it is not updated. When I am making changes in the assembly mode, the feature is at the bottom of the tree , not in the part history tree.
I have worked on parts many times in assembly mode, what changed here.
Make sure you click on edit part instead of simply selecting it.
