Setting the wall height to 42 will have it show a space between the counter and the upper cabinets in the 3d view.
So you need a cabinet with a face on both sides, it's doable but a little involved.
First, set the back thickness to zero for the cabinet you already have.
Then create another wall, 180 degrees from wall #1, with it's height and depth set to zero. On this wall create a similar cabinet as the upper you have but set it's depth to 3/4". This will give you only the face frame & doors for the cabinet and it will show it in the 3d as being part of the other one. |
