How to change the ceiling depth?

[StephenM]

Having a brain fart here and can't remember how to change the depth of the ceiling?

 

Currently my ceiling cuts about halfway through my trusses, but I need the ceiling to be lowered so it sit under the trusses. Can attach a zip file if needed.

 

TIA for any help!

In the Structure tab of the room dialogue box, "Relative Ceiling Height"

Tried playing around with this dialogue box, but haven't had any luck. What am I specifically looking to adjust in there?

I've also attached the plans if that helps.

Select the roof plane and open the DBX, go to the 'Structure' tab. In the 'Roof Layers' section, you an edit the framing. Is this what you're looking for?

So I did that, but it didn't adjust my roof plane to meet the same depth of my trusses. Do I have to regenerate the roof planes after adjust the framing thickness?

Yed, unless you have Auto Rebuild Roof turned on.
