On a PC, the main controls for the build mode in Sims 4 are “M” (move to slot), “Alt” (placement), “Del/Backspace” (remove an object), “[“ and “]” (resize), and the zero and nine keys (move an object up or down). For PS4, use “L2” to toggle an object off-grid or place it, “L1” and “R1” to rotate an object, “L2/R2” and the d-pad left and right buttons to resize it, and the d-pad up and down buttons to change the elevation of an object. For Xbox, use “LT” to toggle an object off-grid or place it, “LB” and “RB” to rotate it, both triggers and the d-pad left and right buttons to resize it, and both triggers and the d-pad up and down buttons to change the elevation of an object.
