Objective: Using CFE to combine two fences into one. Level of Difficulty: Beginner
Please help me to shape this tutorial. If you have any questions, be sure to ask here or in a PM,
and I will adjust this tutorial.
I once wrote a tutorial for combining fences using the foundation tool.
And while that’s still a great quick & dirty tool for combining two shorter fences, it can be
tedious using that method for taller fences.
This is a DIFFERENT method, one that is much more flexible and more reliable.
With this method, you will be placing one fence on the ground, and another fence on a floor above it.
As you lower the floor, the upper fence will lower with it, right into the lower fence that is on the ground.
This will combine the two fences into one.
1. When in CFE, the game will only allow stairs with four steps, so when you place stairs in CFE, they lower the floor 4 steps.
2. Using the ALT key, you can lower ONE step at a time. When in CFE:
4 Steps = 1 Stair
4 Stairs = The height of one level, one story.
Therefore 16 Steps = The height of one level, one story.
a. To lower a floor in CFE, you place the stairs or steps onto the floor, and it will sink on its own. b. Use the Level Terrain tool. Start at the bottom of the stairs and drag outward with the tool. This will take a few swipes,
so be sure to continue from where the floor is already lowered, and drag some more. c. Once the floor is flattened out at the new level, place another stair or step, as needed - till the floor is at the desired level.
The fence in these screenshots is the "Bipartisan Fence." Using CFE, I am lowering the floor to be the same height as the fence.
1. It’s best to plan ahead, and lay down your fencing before you build your house.
2. Your fence should be at least one tile in from the edge of your lot. Otherwise,
if the lot is moved to another lot the same size, the top part
of your fence will knock up to the default height of a wall. It’s very unattractive, and a tedious pain to repair.
3. Once you’ve lowered the floor to match the height of your chosen fence, it’s easiest to add the top fence
before you continue lowering the floor, especially if you are experimenting with the height by lowering one step at a time.
You can see immediately what it will look like, and can adjust accordingly.
4. The game will not let you place one fence on top of the other. There must be a wall or a floor.
So, until you are certain which top fence you are using, and how far down you want to lower it,
it’s safest to leave the flooring in place (on one side of the fence or the other).
5. It’s easier to CASt your fences before you lower the upper fence into the lower one.
I mean, it can be done, but sometimes it’s difficult to select the lower fence once the
upper fence is lowered into it.
6. Remember to get out of CFE before you do anything else. Adding floors, walls, or columns will bring great suffering if your CFE cheat is on.
Okie Doke. Let's put two fences together.
1. Make a room about 3 or 4 tiles wide along the edge of your future fenceline.
2. Place a floor on top of the "room."
3. Remove all roofs, and disable Autoroof.
4. You can now replace the one wall with fencing along your future fence line. And then, if you like, you can delete the other walls while you’re at it.
5. Open the cheat window (ctrl+shift+C).
6. Type in constrainfloorelevation false.
7. Using CFE, lower the floor to the same height as the fence you’ve chosen.
(See CFE review [earlier in this post] for steps involved.)
8. Place the upper fence on top of the lower fence. (In actuality, you’re placing it on the floor, but it will stay there after you’ve deleted the floor.)
9. Depending on how much of the upper fence you want showing,
you can continue lowering the floor using stairs or steps. One step can make a big difference
in the fence’s appearance; you will want to experiment.
10. Once you have determined the best height for the upper fence, and you’re happy with it,
remove the rest of the flooring.
11. Reopen the cheat window, and type constrainfloorelevation true.
Here are a couple of examples with the number of steps/stairs necessary to lower the upper fence:

With this method, you will be placing one fence on the ground, and another fence on a floor above it.
