Foundation wall setup

I am wondering how I can set up my foundation walls and main floor so that I can have a slab on one part and a framed floor on the other that flush out at the same level.
But I would like the top of the ICF foundation walls to have a double sill plate with the concrete poured inside of that where the slab is and the other side would have accommodations for the framing to come out at the same height. I have a simple plan attached and some cross section details of how the top of foundation wall would look.
I know I can just build it with the slab at the same level as the house and then just have these detail drawings included in the plan but I am wondering if there is a way to actually have Chief build it this way?

the screenshots you have show both floors as slab.

 

I'm not understanding what you are trying to do, from an absolute elevation perspective.

 

It's almost like you have a walkout basement with a stepped foundation, if the slabs are at the same elevation, but the stem wall below the slab varies from only a footing to what looks like about 3'?

I believe what you are looking for is called a hung joist floor system.  Open the foundation wall you want to have the floor system hung from and check the options in the structure panel of the wall dbx.

I guess the plan I sent was confusing because I tried to draw something simple to illustrate since my actual plan was to big.
Let's just start with this question: How can I make an ICF wall that goes down to frost footing with a double plate on top and the top of the slab floor is level with the top of the double plate? I have a detail attached.

With a special Wall Definition it is possible, though I am not sure what other issues it may cause down the line.

 

The biggest issue will be that you want the bottom of the slab 1" below the top of the Stemwall as Chief Automatically wants to place the Slab on the Stemwall due to the way chief uses Rooms and the bottom of the floor structure. The simple fix is to spec the floor slab at 3" in the room/floor settings and the use a 4" CAD box in Cross Sections though. ( 3rd pic )

Thanks, I am not sure what you are doing with the wall definition specs here.
But let's even go more basic than this: how do I draw a slab inside ICF walls with no crawlspace or anything underneath, just fill?
And then how do I put a double treated plate on top of my ICF wall?

      Hello.
      My basement slab is not showing in the cross section nor the 3D overviews. 
      I have looked to see if I maybe have a layer turned off, but I do not see any.
      Link to plan is below.
      Any feedback is appreciated. 
      TIA

      Brand new user here! First question: Is there a specific order in which the tutorial videos should be watched to learn with a better A to Z process? I'm watching a ton, but they are not in a helpful order, so I'm taking 2 steps forward, 3 steps back, making error that I have to correct, etc.
       
      As for this particular topic, are there specific tutorials for creating a slab foundation that extends over a sloped terrain? I'm looking to make the footers, foundation walls, and slab. I've attached a screenshot from a CA video (unrelated) that shows the end result I'm looking for, as well as my work showing a floating slab.

      Hello Chief friends,
       
      I've been struggling and searching this topic but cannot seem to come up with the information that I am looking for. Basically, I have a sloping site and want to draw the uphill stemwall (top) 2'0" higher than the downhill wall. The floor system will ledger off the uphill wall, and the uphill stemwall top should finish about 2'0" higher than subfloor elevation. Wood wall framing will then be 2'0" shorter on this uphill side. Additionally, I'll be using some retaining walls extending off of the foundation to retain the up hill fill material. 
       
      I was able to "drag up" the top of the stem walls on the uphill wall to gain this two feet of elevation. However, there are all sorts of issues with wall intersections that I cannot seem to clean up. I think that what I am after is forcing the taller wall to run through, but I can't seem to force that in my foundation drawing or 3d view. There has to be a better way... Also, now the subfloor and some trim is sticking through the stem wall. 
       
      I'm running x12 on MacOSX. 
       
      Appreciate any help you all can provide! 
       
      Thanks,
      Austin

      In my plan I need most of the foundation to be a monolithic slab except in areas where there are pipes such as the bathroom.  I am trying to figure out how to cut a hole in a foundation that I have generated in CA with the foundation tool, but when I try the "slab hole with footing" and the "Hole in floor platform" tools I get errors. "could not create hole in floor platform" and "a slab hole must be placed inside a slab".  
       
      To elaborate on the foundation, it will be piers 4ft into the ground then a normal monolithic slab and footings will be poured on top of the piers.  The footings and slab will sit about 24" above the existing terrain where the piers tops also are.  The soil cap will be course gravel and basecourse on which the slab will be poured.  The bathrooms and other rooms with piping will be to the outside of the building and there will be a crawlspace below those areas to service pipes.
       
      I am hoping someone has experience with this and can help me.  I've scoured the forums and spent hours in CA to no avail!

      This is the first home my team and I have created in Chief Architect (converting from SoftPlan) and we're stuck still trying to figure out if there's a way to show a foundation only plan in the layout using the "walkout" basement, level 0. We end up with the full framed walls showing on top of the 4' stem foundation walls, no interior footings for the interior bearing walls, and a stone veneer on the framed wall above that isn't supported by the foundation wall.
       
      If anyone can offer information on how to get just a true, basic foundation plan in our plan set/layout that would be fantastic! The (nearly complete) floor plan is zipped up and provided below.
