Wall fail dormer window

We cannot finish one wall of a dormer window. I will send you the file.

Hi Simon,

The problem here is the height of the facade wall, because even it has been extended to a lower level it is still generating the joint with the other one. To fix this, the height of the facade wall should be reduced until the roof edge or below.

Kind regards

Thank you. It works fine.
