Hello, when I analyze my balcony opening of 2.5 m in the two-storey villa project, the floor thickness is 20 cm. I want to solve it with a floor thickness of 15 cm. Therefore, can I put a round column on the corner point of the balcony and connect it to the main system without connecting it with a beam? When I try, the floor thickness does not change, it still shows 20 cm, can I make beer like that or I don't know the settings
