OK, thanks. I will check that out.

Thanks for the help, unfortunately I can't find any invisible walls or room dividers above that line. I attached a zip file of the entire plan, non-stripped down, maybe something shows up now? D_J House.Main.zip

I am having Chief Architect X14 build floor framing and it keeps adding a double rim joist in the middle of a span. There is a Glulam beam in the middle of the garage floor, and a bearing wall for the other bearing line but I can't figure out why it is doing this. There are no walls above this floor system. First time posting so not sure what is needed to answer this question. Floor question.plan
