Re: Editing pre-existing sims relationships?
relationship.add_bit <yoursimID> <targetsimID> <relationshipBit>
So, if your grandchild ID is 123 and grandparent is 789, it would look like this:
relationship.add_bit 123 789 family_grandchild
That being said, I have no idea if this cheat works anymore. A lot of cheats (like the skill cheats) were taken out of the game a few months ago. There is a mod out there that will re-enable them. Try searching for TwistedMexi sims4cheats or viewing https://www.carls-sims-4-guide.com section on cheats for more info/help.
