Useful cheats/commands

Cheats I use pretty frequently and any special notes.

Press Ctrl + Shift + C to enter cheats.

[ OR ] when placing wall objects

Not a cheat. Lets you lower or raise wall objects.

aging off

Turns off aging.

Ctrl + Alt when placing wall objects

Not a cheat. Lets you place wall objects as if you have "moveobjects" on.

Ctrl + F when placing floor tiles

Not a cheat. Lets you place quarter tiles when making floors.

boolprop allow45degreeangleofrotation true

Lets you rotate objects at half the angle, only with the < or > keys. Really finicky if you try to put stuff against angled walls, though.

boolProp constrainFloorElevation false

Lets you connect walls to foundations to make functional garages connected to houses on foundations. Look up a guide, but it mostly amounts to just using the level terrain tool a bunch of times.

boolprop locktiles off

Lets you place tiles off the lot. Good for making driveways.

boolprop lotInfoAdvancedMode on

Adds a button on the upper left showing you the lot value, among other things.

floatProp tvVolume [X.X]

Mutes TV's.

Replace X.X with any number value (i.e. 0.1) to change the TV volume. 0.5 is the default, 0.0 mutes TV's.

kaching

Instant $1,000. If you really want to cheat, use "motherlode," but I do this when I'm just a few bucks short of finishing an idea.

modifyNeighborhoodTerrain on

Be careful with this one. Lets you modify the neighborhood terrain with the cursor on the neighborhood menu. \ to flatten, P to smooth, [ to raise, ] to lower, / to level.

moveobjects on

Lets you place items anywhere. Also lets you delete any item. Good for moving mailboxes/trashcans or fixing stuck sims.

PlumbBobToggle

Hides the diamond thing about sim heads.

setquartertileplacement on

Press Ctrl + F to activate. Lets you place objects in quarter-tiles or half-tiles for better centering. Works on ceiling and wall objects, but not rugs.

(Pro tip: just place carpeting with the floor tile tool if you want convincing rugs.)

Shift when using terrain tool

Not a cheat. Lets you invert the raise/lower terrain tool mid-use for more craggy terrain.

Shift + Left Click in build/buy mode

Not a cheat. Lets you continuously place an object after buying it.

showheadlines false

Hides speech/thought bubbles.

Stretchskeleton [X]

Adjusts sim height, 1 is default. Can make utter monstrosities.

Unlockcareerrewards

Gives active sim all career rewards. You can make lots which have these rewards present by having your sim visit them and drop them off.

boolprop testingcheatsenabled true

Honorable mention. Look up guides for this, it does too much to list here. For the sake of cheating, it lets you click and drag bars on the HUD to change their values manually.

boolprop snapObjectstoGrid false
Allows you to place objects without them being snapped to the grid.

boolprop snapObjectstoGrid true
Enables objects to snap to grid when placed
