Re: sims 3: sizing objects in buy/build mode

@Kya10  Those are all Sims 4 commands to resize objects.  There's no way to do it in Sims 3 unless you use mods, or unless you can find custom content in the size you want.  You could ask on the Mod the Sims site if there's any content available for your specific plans; just be sure to post in the Sims 3 section.
