I am trying to figure out the workings of how to create a slab foundation raised/extending 12" above grade or 24" above grade.  From what I can gather would the correct method to be treat the foundation plans as the Basement level with 24" walls ?  If so how do I lower the garage to the correct grade height 12" or 24" lower than the slab ?  What would my settings be for Floor System mode now with the 2 4" slab planes at different heights ?  This is all so confusing but I know if I can see the correct settings done once I can figure it out.   If anyone has a video link to a tutorial on a slab foundation that would be awesome..everything I can find is basements.  Thanks if you can help me
