This sim will now be in the panel on the left hand side with the rest of your family in this lot. With it on, you can now Shift-Click on the sim that you just Summoned, and you’ll see the option in big capital letters “MAKE SELECTABLE”. Here’s where the testingcheats comes in.Click on that and find the sim you want to edit. Then go back to “Teleport…” again, and there should now be a “Summon…” option.Click on the tree, then select “Teleport…” (you may need to click “More…” first) and then “Enable Summon Menu”.(Doesn’t really matter where, but you do need to be able to get to it.) (That’s the stuff under the icon of three dots, if you didn’t already know.) Find the item that looks like a little tree. Go into Buy Mode, then go to “Misc” and “Misc” again.Go into a one of your lots and type “boolprop testingcheatsenabled true”.(I’m sure there are other modded objects that can pull this off, but I’ve found Sim Blender to be easiest.) Namely “boolprop testingcheats enabled true” and the Sim Blender mod. Townies and NPCs, on the other hand, are slightly more tricky and require cheats and mods. Then, if you want to, move them back to the sim bin. Just place them in a lot and, again, change their appearance the old fashioned way. If you mean the ones that already have their own lots, you can simply go into their lots and change their appearance the conventional way. Pre-made sims in the sim bin are also fairly easy.

It all depends on what kind of pre-made sim you’re talking about.
