Ceiling Help

Hi
What would be the best way to create a ceiling on this model? Any other tips for improvement for my assessment?
Thanks

If it is to follow the slope of the roof, I would draw the profile (section) in situ, making sure it was in its own group, then extrude using Push/Pull.

Thanks Simon. What about if you wanted the timber beams exposed so to have the ceiling on the other side of those beams?

Same thing but start on top of rafters instead of under.

Test this model and see if the way it’s organized into groups, components, and tags improves your work.

Thankyou!
