I have an integrated library (Resistors) to which I want to add parts. The parts are all available as separate files. I loaded the integrated library and expanded it into its component parts, getting a library project. I then added my new library files to the expanded list using "add existing document". The new part shows up in the list. However, when I compile the library, the new part does not show up in the new integrated library, only the old parts. And yes, I am looking at the new file in "outputs". Any suggestion as to what I am doing wrong?
