Why is there no change even after adjusting the floor height

When the wall height has been changed but the actual displayed height is inconsistent, please check the ceiling height being displayed. In this case, the ceiling will remain unchanged when the wall height is modified. You will need to adjust the ceiling elevation with the suspended ceiling, or reset the ceiling and apply the new ceiling layers again. If the top wall shape has been properly set, it is recommended to merge and collect it first, then delete it.
