I'm taking lessons on creating a villa, and I'm currently in the Al planner lesson. I want to create the layouts for the first and second floors. Here are my questions: 1. In Al planner, there is no option for creating a layout that spans two floors, so all the rooms are on the same floor. 2. The task specifies a building area of 144 square meters (which is presumably the area of the entire building's projection on the plot). Or is it referring to the total floor area of the two floors? And how should I deal with the Al Planner in the case of two floors? I can't export the resulting single-story plan for our two-story house. Please explain the task.
