Insulated roof / ceiling intersection modelling aproach

Hello, I am trying to model a insulated sloped roof intersection with a insulated ceiling at a collar beam height (pictured below). Haven't been able to search up a best way of approaching this. 
Currently I've tried to model the ceiling part as a slab seperately and use solid element operations to cut off the excess that extends through the roof. Tried the same for the insulated sloped roof portion as a single plane roof, but have run out of ideas how to properly show the connections between these 2 composites.
Maybe someone with more experience can explain how they would approach modelling this specific scenario.

Hi,

You can try modelling the slab part from the same roof composite with 0 slope. That way you can easily keep track of it in schedules. 

I did a quick mock-up of a similar situation and I got these small steps (which are logical to be there from a geometrical POV):

You can try to use custom edges for the roof but it will overlap weirdly:

You can also use multi plane geometry for roof and it will work well but it gives you 4 slanted sides, you can not have a two sloped roof.

a pretty cumbersome method is to make it as a multi plane roof, export it into single planes, delete unnecessary elements and dimension the insulation accordingly but I am pretty sure there are faster and smarter ways to do this. (maybe define some new complex profile or similar)

 

hope this helps.

A multi-plane roof with multi-plane geometry can also have gable ends.

 

You could also use an extruded shell.

A shell can also use composites.
