Im a third year architecture student and I have been creating a model of my design to analyse in sefaira. However, it keeps saying the error message. I have tried many things and it just won’t work. This is essential for my coursework and I need to understand efficiency of the energy and daylighting within my design. The model is not too complicated as I have managed to simplify it. It might be the overlapping lines of the ground and first floor but other than that I am not sure what is causing this problem.
