Question about the roof construction

Hello all,

I am trying to build my first model with the WikiHouse system. I used the size M modules for the walls/windows/doors and the size XXXS for the floor/roof. The butterfly connection of the Roof-XXXS and the Verge-XXXS do not fit together exactly at one point. Does anyone know what this could be due to? I can’t find the error somehow.
I would like to upload a screenshot, but unfortunately can not find out where.

Hi Luise, ive been playing around with roof this weekend and am happy to help. See attached on how to upload screenshots and il see what i can do.


Okay, I found it! Thank you already:)
