Why are my drawings opening with all of the tree collapsed? I want to say this didn't used to happen, but I'm not sure now. Is there a way to open it so at least the contents of each sheet are displayed?
I don't know which version you're on, but I've tried an old version (2013) and it indeed starts with all sheets expanded regardless of the state when the file was saved. If you really want them expanded, I think you could write a little macro to do that. The macro recorder won't record you doing that though.
We're running 2015. Glad to know that my memory was accurate. I guess they changed this behavior at some point then.
