Sims 4 edit sim cheat - how to fully customize your sims

Af Simon - 30 May 2025

In The Sims 4, creating and personalizing Sims is one of the most exciting parts of gameplay. However, once a Sim is created, the in-game tools only allow for limited editing. If you want to go back and make more detailed changes - such as altering facial features, body shape, or traits - you’ll need to use a cheat. Learn how to use the Sims 4 edit sim cheat to unlock full customization through Create-a-Sim (CAS) at any time.

What Is the CAS Full Edit Mode Cheat?

The CAS (Create-a-Sim) Full Edit Mode cheat lets you return to the full character creation screen normally seen only when first making a new Sim. With this cheat enabled, you can change almost everything about an existing Sim, including:

  1. Facial structure
  2. Body shape
  3. Walk style
  4. Voice
  5. Traits and aspirations
  6. Gender and age settings

This powerful tool is great for fixing mistakes, refreshing the look of old Sims, or reinventing a character completely.

How to Enable Cheats in The Sims 4

Before using any Sims 4 cheat, you need to enable cheat functionality in the game. Here’s how to do it:

  1. Open The Sims 4 and load your game.
  2. Press Ctrl + Shift + C (on PC) or Command + Shift + C (on Mac) to open the cheat console.
  3. Type testingcheats true and press Enter. A confirmation message will appear indicating that cheats are enabled.

Entering the Full Edit Mode Cheat

Once cheats are enabled, follow these steps to activate the full edit mode:

  1. Open the cheat console again using Ctrl + Shift + C.
  2. Type the following cheat exactly:
  3. cas.fulleditmode
  4. and press Enter.
  5. Now hold Shift and click on the Sim you want to modify.
  6. From the menu that appears, select Modify in CAS.

This will bring up the full Create-a-Sim interface, where you can make detailed changes to your Sim just like at the beginning of the game.

Tips for Using the Edit Sim Cheat

Be Cautious When Changing Certain Traits

Although the edit mode unlocks all editing features, changing certain aspects such as a Sim’s age or aspiration may affect existing storylines or gameplay progress. For example, changing a child into a teen could result in mismatched relationships, so be sure to consider these factors before making drastic changes.

Useful for Storytelling and Machinima

For players who enjoy creating stories or machinima using The Sims 4, the full edit cheat is a lifesaver. It allows for quick changes to character appearances, helpful when changing hairstyles between scenes or adjusting a character's look to reflect progression over time.

Common Issues and How to Fix Them

CAS Changes Not Saving

If your changes in CAS are not saving properly, make sure you’re not in a household or game state that restricts modifications. Exiting the game and re-loading can often resolve this issue.

Cheat Not Working

If the "cas.fulleditmode" cheat doesn’t work, double-check that "testingcheats true" is entered first. Also, some mods or outdated game versions may interfere with cheat usage - ensure your game and mods are up to date.

Conclusion

The Sims 4 edit sim cheat is a must-have tool for players who want complete freedom when designing their Sims. Whether you're fixing a mistake, evolving a character, or just having fun with styles and traits, this cheat opens up limitless possibilities. Don’t forget to explore in moderation and have fun experimenting with the power of Create-a-Sim at your fingertips.
