How do you freely place objects anywhere in Sims 4?

with bb.moveobjects on you can also raise and lower things with the 9 and 0 keys, and Shift with ] or [ makes objects bigger or smaller. great for clutter on shelves.

Two things. Hold Alt while you drag something and it ignores the grid, so you can nudge it anywhere. For putting stuff where the game normally won't let you (overlapping, on top of other objects), open the cheat box with Ctrl+Shift+C and type bb.moveobjects on. Turn it off again when you're done, it makes it really easy to bury things inside walls by accident.
