This is more of an FYI than a question. We had an assembly that would not display it's components. After trying many different things and searching the forums I found nothing related to what the problem turned out to be. It turned out that there was no display state selected. Once I picked a display state the models showed up. I didn't think it was an option to not have a display state selected. Not sure how it happened but I wanted to put this out there for anyone else that comes across it.
