Window not cutting the walls

[Paulina_Gojska]

Hi, I added windows but they are not cutting the whole wall. It look like this. What should i do?

[azad.Nanva]

you should JOIN the walls.

It's one wall 😕 it's 40cm

[azad.Nanva]

is it Stacked wall,if yes so that should use JOIN there too, in the normal i use the extra Curtain wall with empty system panel for cutting the wall. another ask: check or change your View Range .
you can post your file here.

Check Automatically Embed in Curtain Wall Type Properties.

Do you use an Opening Cut or Void for the opening? If it's a Void, then it's not big enough.
