Small 24 x 36 house slab on grade, 24" crawlspace

[Clemsongrad]

This house has changed sizes 6 times and I'm wondering if I should just draw it all over. 

 

I'm not sure how to create the house with a slab on grade with a center thickened slab with 24 " crawlspace (3 concrete block high) then conventional floor rafters (or possibly floor trusses)

 

When I drew the slab as a stand alone drawing I got some funny conditions even after a bunch of you jumped in to help.

You have a foundation as level 1.  It should be on level 0

Let me try to understand:  You drew a plan and have changed it 6 times.  You want a slab on grade and then build a stem wall with floor joist.

Draw the house walls first then build foundation (stem wall).  Add slab later.

I don't know how to get it on level 0 after the fact.

 

To RG, I don't care about the order. Whatever works best, but yes to slab on grade with stem walls and floor joists.

Normally you would:

Build your crawl space walls on level 1 and your main floor walls on level 2.

Auto build a mono slab foundation.

 

In your case:

Build Floor...Build Foundation with mono slab.

You will now have a mono slab on level 0, a crawl space with wall on level 1.

Now build level 2.

 

You will need to fix things like floor/ceiling heights and structure types as well as wall definitions.

 

There are any number of ways to get where you want, but the above is a basic outline.
