Hello, There is a 6m ground floor in a project, and there are 30cm thick curtains in the building. The structure is about 50m high and the core curtains reach this height. When I do the geometric control of the model, I naturally get the error that the thickness of the header area is insufficient in the ground floor curtains. My question is how can I model the curtain end region arrangement at the junction of two curtains. Thank you Kutay
