Floor Heights Connected Across All Rooms...

...I select the garage and lower the floor to -4" - ALL the other rooms assume this -4" floor height. Probably simple but am stumped again by the structure dbx.

If you lower the garage,  of course it will lower the rest of the rooms because.......  if you go to your foundation plan,  it is one BIG ROOM.  Put a footing under the walls that separate the house from the garage and you will find that the garage can now be lowered without lowering the rest of the rooms.

 

Whenever you have two different floor heights for a mono slab,  the slab itself must be divided into separate rooms.
