Unable to replicate wall-roof join profile

Good morning, I am unable to replicate the intersection between walls and roofs as shown in the figure, even though I have configured the same section type for both objects.

This is my situation:

Hello Alessandro,

it seems the walls with the roof are ok, but the horizontal slab with the roof is not…

Hi @Alessandro_Barbisan I can see this is an extended wall. Just change the height of the wall so it goes beyond the roof. Does that fix the intersection? if it doesn’t, please share the file, so we can take a look. Thanks!

Hi @fsalla I tried to change the wall height but nothing changed. I’ll send you the file so you can check it.
