Floor and wall interaction

[l_tofastrud]

New Revit LT user here.
I need to draw the above system. There are a few issues with what I have tried so far.
The wall system wants to sit on top of the floor system if I include the subfloor and finish floor in the floor type.
If I remove the two top layers and offset the concrete floating floor down from level to then add a different floor system with just the two wood layers, they go into the stud layer of the wall type.

I have the same issue with ceiling construction.
Any help is appreciated.

Attach the wall base to the floor.

Join Geometry will remove volume.  So, if the sill plate is overlapping the Floor finish layer, joining the Floor and Wall together (in correct order) will remove the finish layer of the Floor where the Wall overlaps it.
