Controls for The Sims 4 on consoles (Outdated as of February 2023)

I play on PS4 and I have to say this guide was very helpful, I wish I had found it much sooner. But I watch a PC gamer build and I’d like to be able to copy all of his tricks. Is there any way to bring one side of the eaves of a roof in without the other following, in the PC game, he just holds shift and drags the arrowhead. Also, I know you are supposed to be able to finely adjust certain things like the roof height, but I can’t figure it out.
