Different Foundation Types in Same Plan

[MississippiMims]

I would like to add a walkout basement to a house that I originally set up as a slab on grade.  As you can see in the attached images, I can easily click "add foundation" and set the ceiling at 100" to get a basement.  However, the basement will only be on the back of the house.  The customer wants a raised foundation so that the house looks conventional from the road.  The front section needs to be "footings with walls" but needs a slab at the top of the walls.  I have a couple of questions.  1.) How do I accomplish the slab at top of the walls and still have floor joists over the basement section?  2.) How do I get the same raised foundation condition on the front porch?  I searched the forums and David and Eric's YouTube channels and haven't found any guidance on this specific condition.

@MississippiMims Is this what you are wanting? I started with footings and foundation walls on everything then changed the back section to basement. I then changed the front section floor structure to concrete. I lowered the one wall so you can see the slab built out over the foundation wall.

Thanks Gary.  As you can see, I'm still having an issue getting the concrete slab on the whole front section.  When I try to change the floor structure over that area, the floor structure dialogue box is grey (I can't click on it).  I defined the back part as a basement but still can't get my floor trusses to show up.  I will try to attach the plan as well.

Since you already have the rooms drawn you will need to divide some of them with room divider. Then set the floor structure of the front rooms.

I added the room dividers and changed the materials to concrete as you show but I still have several problems.  My section (attached) is very confusing.  For some reason I still don't have a solid foundation under the front, and my floor joists aren't showing up.  Also I don't want the room divider to show up in my floorplan but I need the room dividers to show up on the porches.  Is there a better way to approach this condition on the set up?  I am willing to start completely over if it will help make a presentable section for my layouts.

I started completely over and tried starting with foundation walls with the "slab at top of walls" selected.  As you can see, I can't get the slab to appear.  Am I missing something?
