Friends, how can I define different floor heights on the same floor. Let's say on the 1st floor, the floor height of one part of the building is 3.5 meters and the floor height is 2 meters in the other part of the same floor. How can I define this different situation on the same floor. The part that is 2 meters is 1 meter higher, therefore, when we look at these floors, the ceilings of the floors are at the same level. What is the way to define different floor heights and to adjust the elevation situation I said. Another question is how do we adjust the shaft gaps in the floor. the gap starts right next to the beam. Since I couldn't quite catch this part, when I get closer to the floor, I see that there is a small piece of flooring between the gap and the beam. I need urgent help. REGARDS...
