Also on the other side of the living room wall the steps actually protrudes into the kitchen wall above the door to the basement steps. There's a soffit there to contain the top few steps to the upstairs floor. This makes it too complicated or impossible to use SVG since it only cuts through floors/ceilings right, as far as steps go? My soffit "box" object in my SH3D home is not a wall anyway. I'll have to make a hollow version w/doorframe wall section and export as OBJ to import as a replacement for this area.
