Hi,

whenever a wall comes through a roof, the roof side is internally damaged and unable to cut the wall down.

In your example using two roofs and merging them is not best and not necessary for several reasons.

Such a roof should be inserted as one polygonal piece, with a small step in the outer contour to create an additional roof side for the gable end.

A small step here means, that I have forced the roof to create an additional roof side by extending the roof polygon at the gable end 3cm away from the wall outline.

Attached a screenshot in which I have marked this 3 cm step and your project file with this new roof in it.

Hi, here is another example of two gable end roofs being merged together , but walls of the upper floor just extend up on the outside of the roof AFTER the merger.

HI, can someone tell me why, when I merge two gable end roofs , the walls of the attic come right through the roof.

I have tried closing down programme and starting again, deleting attic and starting again but it keeps doing it.

Thanks for any suggestions.
