Hello Jalal!
Perhaps you have the wrong height (
Sill/header value
) on the window. Look on the picture (under) what happens if I set the window sill to 3000mm over the floor while the wall is only 2700mm high... the window rises over the wall and into the next floor...
The window will be visible (barely) in 3D but not in Floor Plan.
Hope this will help!
Good luck, Jalal!
