Re: where is the create a sim menu
Tap on an empty house and the first selection in the menu that pops up is create a sim. That is the only way you can do it. If you want to delete a sim, just tap on the sim and tap on the red circle on the top right of the dialog box. If you want a sims to move out and the two sims are not married then you just tap on an empty house and it's either the first or second menu item. While hou have that menu up I would suggest you look at each selection so you know what they are.
If your two sims are married then the will need to divorce before one can move out. Just do the red,social interactions with them.
