Yes, ok, but most often I have H=2,8 m and ceiling 0,20 m so total height is 3.0 m. I have walls 25 cm thick, RC ring has dimension b/h=25/30 cm and lintel is b/h=25/20 cm. So the RC ring has bigger height than the ceiling. If I put lintel directly under ceiling the RC ring would penetrate trough lintel. So it is not clear which element (lintel, RC ring or both) carries a vertical reaction of ceiling.
There is also a problem when I have doors which are 2 m heigh. If I put lintel on top of a door it is 2,00+0,20= 2,20 m. Space between lintel and RC ring is then 0,50 m, and space between lintel and ceiling is 0,60 m. It would be much easier to control geometry if the RC ring would be rendered in geometry view.
