I was creating a weldment part and made a cut feature that will be common to other parts. I thought that I would be smart and try to make the cut into a library feature.
In the process of creating the library feature, the reference file over wrote my base weldment part....and it's missing about half of the features and renamed cut list items etc. I'm trying to recover or undo but it seems like I'm SOL. Couple hours down the drain.
What did I do wrong? How can I prevent this?
