I haven’t needed to do a separate foundation plan, so I don’t know how to make chief do what I want, I will try to describe what I’m wanting to do. I’m doing a 18” x 18” footing a 6” wide by 12” tall stem wall and then pouring 4” thick slab in between the stem walls. I want the brick on the walls to go down to the top of the footing, the 2 x 6 walls will set on the top of the stem walls. The outside edge of the stem wall in the foundation plan should be the same dimension as the outside edge of the stud wall (main layer) in the floor plan. I have watched videos and read but I’m just not understanding, I’m pretty thick headed, any help would be appreciated. Thanks everyone in advance.
