So many possibilities with this new tool, it’s amazing. My favourite part is creating stairs with it and yes, it IS possible to this. They are a little buggy and the routing can look a bit odd though. My Sim walked through a wall a couple of times but managed to get to the top without any help from me.
There are, of course, some annoying glitches with them:
- building a platform in a room demolishes the wall if the platform is built against a wall. The wall can be rebuilt but it is very annoying.
- some objects cannot be placed up against a platform, for example kitchen counters. This is easily rectified by making sure MOO is enabled.
- if you demolish a platform you may not be able to place objects where the platform was. Enable MOO and you should be good to go again.
- rounded platforms don’t play well against straight edged platforms and foundations.
I made a video showing a really quick small build with platform stairs and platforms on the upper level. If you use platforms like this remember that you do need to place a one step stair from the top of the tallest platform to the floor of the higher level otherwise your sim will not be able to access the upper floor.

First of all – fantastic little build! I wanted you to keep going! LOL
I did notice that it seems like the routing “breaks” when the Sim has to turn a corner as they move up/down the platforms. It’s interesting that they kind of go “outside” and then come back in once their orientation is altered to the next direction.
I’m holding (for the moment) on installing Big Sur – I want to make sure I don’t break my game just as we have so many new goodies!
Plus, I haven’t even gotten to reinstall my S3 and play with it yet! 🙂
Thanks for all you do for our community – both here and on the EA forums. I really do appreciate it!

❤ This was my second build using platforms as stairs and the routing didn't show this in the first one. I figure it's just a bit glitchy, quite entertaining though 🙂
