Foundation Building Under Interior Walls

[OrinCrowder]

Can't figure this out. Walls for two interior rooms - walk in closet and laundry/pantry combo - are extending through the floor. When I build the foundation it builds separate foundations under those rooms. Tried deleting and re-drawing with same result. Wall and room structure specs same as other rooms. Toggling "Build foundation below" on and off has no effect. Any ideas? Thank you.

Here is an example of a simple building with one of the interior walls being set to be load-bearing.

 

 

 

Pictured below, is the resulting automatic foundation generated.

 

 

 

 

I think this is why CA is creating walls and footings below some of your interior walls.

 

It may be also that those areas in your screen clip have a different floor level that is lower than the surrounding floor.

Thanks. It was the different floor level. No idea why it happened while drawing walls as I normally do but problem solved.
