Hello, I have a project and since I upgraded to ide 8, these strange errors have been renewed, for example 1. I say take a section in the formwork plan on the hollow floor slab. 2. There is a 4 m wide 70 cm eaves slab on the roof. It gives an error that the reinforcement is insufficient. If you define the slab as two different slabs, it does not give an error. 3. I take the colon application plans, I say open it inside, it opens outside. I will be glad if you can help me how to solve these problems.
