Friends, there is a small village project, ground + 1 floor. How can we make building codes? I have included the architecture of the project in the appendix. It seems that the building is standing at + 0.50, I tried to set some codes, I guess it didn't work. I made the changes from the floor general settings. As the architecture appears on the staircase, it must start from 0 and lead to the entrance of the building...
