Attaching wall to a roof problem

[Mohamed_Faramawy]

i am trying to attach this wall to this roof but that happens ? do anyone have an idea why ?

[dzanta]

select wall, detach first...

then try reattaching again

if that does not work....

double click wall to edit profile and draw magenta lines for outline of wall based on roof.

The wall must be completely within the roof boundary.  If your roof has overhang then the overhang may cover the wall but the actual boundary may not.  Check that.

Possibly each half of that "roof" is really a separate Roof element, and when attaching the wall to it you clicked on the left side?

i am attaching the file for u all to check it

Make the wall shorter (horizontally) and it will work.
