I have Sims 4 and there are some pretty neat aspects to it, but I still don’t have as much creative liberties in it as in Sims 3. So yeah, I’m back to playing Sims 3 and learning new tricks for it even now: Split levels for instance!
Here’s a quick how to:
1. Draw your floor plan using the Wall tool. Wherever you want to make a split level – a stair landing for example, draw that in just as you would a room. move one square out from that and outline that level. This last is just to make your life easier if you’re making a stair landing. You do not need to do this if what’s next to it is just going to be a room a level down.
2. Turn the dang auto-roof off, go up a level, delete the roof, and build another story. This time, follow the room lines below but not the split level lines. Floor the whole second level. Because there are no walls here to designation the split level zones, you might want to do those in other colors just so you can easily see where they’re at.
3. Go up a level. Draw the outline of the building only. No need to floor it. Just leave it open.
4. Go up a level. Just floor it. No walls or anything else. This will be the second level of your structure IF you choose to have one or it will be your roof level if not.
5. Go back down to the 2nd level, hit “Ctrl+Shift+C” and type in “ConstrainFloorElevation False” and “Enter” in the gray bar that appears on the top of the page.
6. Choose where your topmost split level will be and drop a staircase down either in the center of it or at the edge where you want a stairway anyway. This is a bit tricky sometimes. You may have trouble getting the stairway to land exactly where you want it. It may fight you. But all you really need from it at this time is for it to make a dent in the floor. Once it makes that dent, if the stair is not exactly where you want it, just delete it. Then use the terrain leveling tool to make the whole floor level with the dent.
7. If this is a landing, delete the floor surround this split level 1 square all around except where it meets the wall of the house or an interior room that will not be directly connected to this level.
8. Now drop another stair where your next split level with be. Unless the stair has landed exactly where you want it, just delete it and level the floor from that level across the structure, leaving only your top most level alone and separated by the 1-square divide.
9. Make your 1 square divide around this level too.
10. Delete the floor except where your split levels are on this first story.
11. Floor the ground in this space. Make sure it’s level but resist the urge to level the lot. It will affect all the other layers you just made so, trust me, you don’t want to do that. As is, you will have to watch carefully to make sure your other layers are not altered and relevel them on occassion that they are affected.
12. Choose where your windows and doors are going to be on this first story. Delete a square of the lowest level wall for each square of width the window, door, or arch will be. The wall levels up will be pushed up above it. Put in the space for each opening this way and if you have several in a row along one wall in a room, go ahead and raise the whole space as one. Just be sure you stop at least 1 sqaure away from walls that will run perpedicular to this. You may experience grief if you do not.
13. Go to the top of the structure. There will hills and mountain peaks there for every place where you raised a wall for opening. Just use the terrain tool to level them back out.
14. Now drop a stair on that top level. Delete the stair and level it out again from the dent. Repeat.
15. Type “Cntrl+Shift+C” and type in “ConstrainFloorElevation True” and Enter, followed by Esc.
16. Now you can put in your doors, windows, fire places, and stairs where you want them.
17. For wall covering where there is a transition between levels, the only way you can hide the way the wall slants between levels is to use solid colors, stucco, or vertical geometric patterns.
