To create a foundation at a different level under the elevator shaft, create a space under the elevator perimeter curtains with the "floor gap" command after defining your raft floor. Then create a closed area with the edge of the raft slab on this place where you define a gap. Place a new raft floor in this enclosed space. Set the level by entering the raft flooring properties. Calculation axes and working distances of raft floors can be arranged as in the sample project. but how can I define and solve the circumferential wall thickness of the elevator shaft in 75 cm system here? imageshack.us/my.php?image=111asd.jpg]
