This tutorial will show you how to use DummyLevels to create Half-Walls.
*more random babble about walls will be inserted here later*

---

1) Create a 9x9 sized room on top of a foundation.


2) Inside this room, add some walls like shown. These are going to become our half walls.
The gap in them that you can see is so that sims will be able to travel between the two rooms.


3) Add another level on top of the first one, but leave it empty. This is our "dummy-level"


4) Using the connecting stairs tool, place two sets of stairs in a row, so that you make a hole in the ground 2 squares away from the house like shown.
If possible, try and make the resulting hole line up with the internal wall as highlighted in green.


5) On the other side of the house, add 3 sets of connecting stairs in a row. It doesnt really matter where this hole ends up.


6) Using the connecting stairs tool, hold down CTRL and click on each staircase to delete it.


7) Add a piece of foundation to the bottom of each hole.


8) Now select the 3rd type of foundation.


9) Hold down the SHIFT key, so that you can place this deck on top of other pieces of foundation.


10) Add two of these column decks to the lowest hole.

Next, you will need to turn on a building cheat.
Here is how to do it:
To enter in cheats, press and hold down CTRL, SHIFT and C.
You should see a small white box appear in the top left corner of the screen.
Type in boolProp constrainFloorElevation false and press enter.
This will allow you to change the height of things you wouldnt normally be able to.


11) Go down a level, then drag a floortile from the top of the left foundation into the building, to the point where the halfwall makes a turn.

12) Drag the floortile along the other wall to finish off to creating your halfwalls.


13) Remove the floortiles inside by holding down CTRL and SHIFT then clicking on a tile.


14) If you want, add floortiles to the places shown, to decrease the width of the walls that are lowered.
This step is optional! It will just allow you to place windows or doors closer to the halfwalls later on.
Remember to delete the floortiles when you are done.

15) Go up a level, and you will see that the roof is also very distorted. To flatten it out, you can just use the flatten terrain tool and drag it from your deck to the edge of the roof. (This is an alternate method to flattening structures with floortiles... they both produce similar results, so use whichever you find easier)

16) Depending on where you placed the stairs at the beginning, you may need to do a bit more flattening in order to completely flatten your roof.


17) Its time to remove our temporary "guide" structures.
Select the foundation tool, and whilst holding the CTRL key down, drag across the top of the foundation to delete it.

18) Repeat this process to completely remove the guide foundations.


19) Turn off the cheat by hitting CTRL-SHIFT-C and typing: boolProp constrainFloorElevation true
Now use the flatten terrain tool to remove those holes from the ground.

20) Congratulations! Your advanced half walls are complete! The dents in the walls are filled in by our dummy level. Note: Do not add windows or doors to the warped walls, as they will not look right.

Because we used a dummylevel for this tutorial, the top floor of the house is still completely useable, unlike in the simple half-walls tute.


Here is my finished version of this tutorial. Its still pretty boring! If you are going to use half walls, experiment with different designs...


These are the half-walls I used in my Aneuri house, overlooking the loungeroom below.
If you look at the background of the picture you can see I have also used the techniques from this tutorial to create two levels of quarter-sized walls on top of eachother. See what you can come up with :)
