Hi guys, I have been having trouble with my walls once I place a column in them (used to present a rotating door). The walls end up having a piece of them removed when I place the column inside them. Not just the circle part but an entire section. Even when I delete the column, the wall still has a gap in it and it has been doing this to me for nearly two years now. I have attached a photo. please let me know what you think. thanks. I LOVE ARCHICAD
