The ceilings in this house are all strapped (which is common practice around here) and I have that implemented in HD as a Ceiling Finish using a Frame Lowered Ceiling with Air Gap = zero and Framing Thickness = 3/4"and Ceiling Finish = 1/2".
This creates situations where gaps caused by the the 3/4" strapping are not automatically closed and I'm hoping there is a way to direct the software to fill this gap rather than circumvent the issue by not using strapping and setting Framing Thickness to zero.
These 3/4" gaps appear when I shut off "Flat Ceiling Over This Room" in the Kitchen which opened up the Kitchen ceiling and shows the gap at the transition to flat ceiling in the hall.
They also show up when adding skylights.
Sorry if this is already addressed elsewhere.
