Walls displayed as dashed below Slabs

[FiestyFejioa]

I'm doing a student assignment and i'm supposed to replicate the attached. As instructed it's been modelled with slab (table top), beams (table top surround), walls (support bars) and columns (legs). What settings do I adjust to get the walls to show dashed below the slab as in the exemplar? File 2 is the disaster i'm trying to fix...

model view options (document > model view > model view options), show beams hidden line under slab. You may also need to adjust the beams hidden line type
