Garage slab and foam tapering to nothing

[Chief-Tony]

I have a attached garage that the slab tapers to nothing in the back. I've tried deleting the back wall to redraw and the taper just moves to the next wall. I've spent a few hours with it and well...https://www.dropbox.com/s/ofxxuyrypgd3y9g/Joseph %26 Johnson One Level Flat Roof.plan?dl=0

Go to the foundation level and run a new wall between the back of the garage and the laundry room. That should remove the taper but also go through all the room heights and floor heights. After that wall is placed make sure the laundry room 'foundation' ceiling/floor heights match the rest of the rooms. 

 

It looks like the foundation was drawn manually with your custom ICF walls? Not that there's anything wrong with that but If you check the kitchen structure tab there's a Build Foundation Below box that is not checked. Perhaps the smart guys will chime in with better advice/help.

You know something?  I have wanted to do this on purpose sometimes and could never do it!   I am still trying to sort out what is going on here.

That's too funny Doug. I was thinking of it as a feature request too.

 

It can be fixed with a new foundation wall but have no idea what's causing it.

 

If the bedroom wall is disconnected from the garage wall the taper disappears. So somehow the interaction of that bedroom wall starts the taper down to nothing?

 

Also if the room is not designated as a garage the taper goes away.

I think this is a bug, if you delete the foam layer under the slab it doesn't tapper to the back of the garage. You should send to tech.

My bad, I just reopened the plan and placed a foundation wall under the garage partition wall. Made the laundry floor the same height as rest of interior (0")
