I'm working in OpenStudio. I have put a geometry into a file. I then load a library that has relevant constructions, schedules, loads, etc. From those items, I add constructions, construction sets, schedules, schedule sets, load descriptions into my file. I have not yet assigned any of those items to a space, but I believe they are part of my model. Then I save my file. When I close the file and then reopen it, all of that work is gone. None of the sets or lower level components remain.
Any suggestions on where I am going wrong?
