How to create a closed eave soffit with an open gable?

[TheMatteus]

I'm using version X14, and there doesn't seem to be a way to differentiate between gable and eave soffits.  Here are pics of what I have currently and what I am looking for, as well as the structure settings I have set.

All or none.  Pretty sure you will need to model this you will need to select it as no soffits and then place ceiling planes for the enclosed soffits.

That’s what I was afraid of. Thank you for verifying

Thank you Eric.  Just to verify it looks like you chose settings for open soffit and then made a symbol for the soffit box and sized it to fit for the eave?

I've done it making two roofs:  The gable overhang has open soffits, the one starting at the building line does.  Not pretty in plan view, but does the trick in 3D.

Wow, never done duplicate roof planes. Brilliant. Thank you Gene!
