How to Change Your Sim's Traits in The Sims 3

Last Updated: May 6, 2021

Tired of your Sim's traits on the Sims 3? Luckily, there is a simple trick you can use to change their traits anytime, not just in character creation. Now you can change your Sim's traits as many times as you wish!

Steps

1
Hold down the 'Ctrl', 'Shift' and 'C' keys on your keyboard at the same time. A box should pop up at the top of your screen. This is the cheats box.
2
Type in "testingcheatsenabled true" into the box. You must get the spelling and spacing right or it will not work.

3
Press 'Enter'. This will enable some of the extra features in the game to work, including this cheat.
4
Hold down the 'Shift' key and click on the Sim you want to change the traits of. Many options will pop up around that Sim; make sure you don't click the wrong one, as you can inadvertently change some other features of your Sim!
5
Choose "modify traits for active sims" from the options. That will take you to a pop-up where you can edit the traits for the sim you chose.
