Please help, i’m new here!

hey y’all, i’m a new Simmer and i’ve discovered my favorite part about Sims4 is building cool houses!! I have learned a ton of tips/tricks/cheats recently, but one of them hasn’t been working for me. I play on PC and i’ve heard that with bb.moveobjects on, you can use the bracket keys to size up or down objects. this has not been working for me! any ideas what i’m doing wrong?
