SEOs for walls and slabs do not show in plan.
You will have to fake the plan with lines and fills.
Only multi-plane roofs, morphs and I think shells will show SEOs in plan as these show a true top down 3D view in the plan.
All other elements are simply represented in plan an do not show their true top down view.
There is one way to do it in version 17 though if you use the "New 3D Document From Floor Plan" command when you right click on the floor plan.
