how to create U-shared stairs in Sims 3

The following is my own construction method to create U-Shaped stairs. We will create a U-shaped stair on a foundation or straight on the ground.

(I would like to thanks to BlackGarden for useful tutorial of Creating L-Shape Stairs. I used it for my first L-Shape stairs and on these U-Shape stairs.)

With foundation:

build a foundation

1. At first, create a foundation and a room two floors.. (We need three frames for the U-turn. That’s why I’ve created a room 7×3.)

2. Count to backwards 7 frames from the corner and make three steps. Now, remove the stairs.

turn down the terrain

3. We have turned down terrain. Place one square of foundation and make two floors on the lowest level of terrain. Then, turn to the side. In here, count to backwards 5 frames from the corner and make two steps. Now, remove the stairs.

4. We have turned down terrain again. Place one square of foundation and make two floors on the lowest level of terrain again. And now we have to column. We need a cheat.

constrainfloorelevation false (Hit Ctrl+Shift+C and type into the box constrainfloorelevation false and press enter.)

drag top of first column to corner

5. Go to the second floor and walls are down. Go to the terrain tools, and choose the level terrain tool. Now drag from the top of your first column to the corner.

place the stairs

6. Place one tile of floor at the corner of your stair. Place your stair at the corner.

drag second column

7. Then, turn to the side. Go to the terrain tools and choose the level terrain tool. Drag from the top of your second column to the corner.

mistake tile

8. Place one tile of floor at the corner. When you place a tile, there been a mistake. Not very important. We can fix it.

9. Go to back the terrain tools and choose the level terrain tool again. Drag from the top of your first column to the corner.

place second stairs

10. Ok! That improved. Place your second stair at the corner.

place third stair

11. Place a tile at the second floor and then place the third stair. Yes, we made a U-Shaped Stair. But it isn’t over.

use level terrain tool

12. We must fix the top. This is easily fixed with the “level terrain tool.” Go to the terrain tools and choose the level terrain tool. Drag from the high corner to the lowered corner as shown. It’s fixed!

Now, turn off the cheat “constrainfloorelevation true” (press Ctrl+Shift+C, type constrainfloorelevation true and press enter.)

remove outside wall and foundation

Remove outside wall and foundation. Yes, it’s over.

On the ground:

We will use the same method but we will not do foundation. We will start from the ground.

how to create U-shaped stairs from the ground

1. At first, create a room two floors. (We need three frames for the U-turn. That’s why I’ve created a room 7×3.)

create two room floors

count to backwards 7 frames

2. Count to backwards 7 frames from the corner and make three steps. Now, remove the stairs. We have turned down terrain. Make two floors on the lowest level of terrain. Then, turn to the side. In here, count to backwards 5 frames from the corner and make two steps. Now, remove the stairs.

make two floors on the lowest level of terrain

3. We have turned down terrain again. Make two floors on the lowest level of terrain again. And now we have two column. We need a cheat. “constrainfloorelevation false” (Hit Ctrl+Shift+C and type into the box constrainfloorelevation false and press enter.)

4. Go to the second floor and walls are down. Go to the terrain tools, and choose the level terrain tool. Now drag from the top of your first column to the corner. Place one tile of floor at the corner of your stair. Place your stair at the corner.

place second stairs

5. Then, turn to the side. Go to the terrain tools, and choose the level terrain tool. Drag from the top of your second column to the corner. Place your second stair at the corner.

place the third stair

level the top

6. Place a tile at the second floor and then place the third stair. Yes, we made a U-Shaped Stair. But it isn’t over. We must fix the top. This is easily fixed with “level terrain tool.” Go to the terrain tools, and choose the level terrain tool. Drag from the high corner to the lowered corner as shown. It’s fixed!

7. Now, turn off the cheat “constrainfloorelevation true” (Hit ctrl+shift+C, type constrainfloorelevation true and press enter.)

8. Remove outside wall and foundation. Yes, it’s over.
