Need floor truss to sit on interior foundation ledge

[K-Lynn]

I am not sure why I can't get my foundation heights and interior ledge to show properly. I have 'hang floor platform above on wall' checked in the foundation wall defaults and I've also checked it in each of the individual wall specs as well as 'include ledger'. I am wanting an 11ft high stem wall. Also, in the room spec structure tab I cannot get the section to appear properly. I'm not sure why it is not working for me this time. Any thoughts?

If you are after a ledger where the wall rests on the concrete stem wall, you can do that with a Pony Wall.  were the upper wall is 6" wide (12" high) and the lower wall is 8" wide and the remainder of the height.  This way your floor truss can rest on the concrete.  You will likely need to manually place the plate or a CAD box for the plate.   This example below is using a stick frame wall.

The Structure TAB CS is NOT a true representation of the actual Model , it is used to Reference Heights only as a general rule, it is best to cut your own Back clipped Section through the Foundation Wall , which I think you have done....

Will need a little cleanup in the cad detailing of your cross sections but if you use a "partition wall" for your ledge and offset your footings you can get this to build correctly.

 

Setup the exterior wall to hang floor platform from it.

Here is how I did it:

 

Foundation Wall with a Joist Lug Using a Pony Wall:
1.    Set you basement defaults (Floor 0 Defaults) for the basement “floor elevation” and the “stem wall height” desired. 
2.    Set your foundation defaults to “Hang 1st Floor Platform Inside Foundation Walls”.
3.    Create a pony wall with the desired “upper and lower wall types”, ”elevation of lower wall top” and “align pony wall” at “main layer outside”.
4.    Add a wall cap to the size of the sill using the horizontal offset to position it correctly. (CA will automatically place it over the top of the lower Pony Wall.) Change the wall cap material to treated lumber or as desired.
5.    Use a CAD Cross Box in elevation to detail the sill.
