wall-soul joint

[saluzzidan]

Hey, guys.
You explain why I can't join the top floor loft with perimeter walls?
and yet it is the same floor of the underlying plan, which does not give problems.

because when I try to unite geometries, he says to me: "The highlighted elements are joint but do not intersect"... ?

thanks to all

I answer myself.

It was enough to combine the geometries of all perimeter walls with those of the loft and voilà.
