The first floor, the standard layer, the top floor of the staircase how to spend days. Is it the same as the plane, broken in the middle of the second staircase? Because the bottom of my stairs is shaped.
Top floor: the ceiling of the staircase modeling position (no staircase at the bottom of the ceiling shape part).
Standard layer: should be in the 1800mm height at the end of the projection (the line is still the first floor staircase ceiling position) at the bottom of the staircase ceiling shape.
The first floor: should be cut at 1800mm height of the stairs at the bottom of the ceiling part of the decorative decoration.
