hi i had some questions at some points, 1 . What is the z symbol in the raft base report? 2nd . If there are no perimeter curtains in the basement, isn't there a rigid floor? Even though there are no curtains, if we consider the basement as rigid, there is no change in the report, I wonder what kind of change occurs in the calculations? 3. What does the object body color mean in the drawing settings? I couldn't detect it.. 4 . For example, how do I write the ground floor formwork plan text as ground and normal floors on the sheets? maybe those who know autocad know this but my autocad is weak yet i will develop it.. 5 . For example, after drawing the mold plan, the reinforcement text stays above the reinforcement line and the reinforcement length text remains below the line or vice versa. I would appreciate if those who have knowledge of these questions can answer, thank you..
