I think you have to hold down the alt key to get stairs of less than 4. I like to do that a lot as I am an anti-stairs kind of simmer. (They take more time!)
Here's an example:
You can place one platform on another, but sims won't always use the platforms normally. So, adding stairs to them while holding alt, make them usable.
If you don't mind using CC, these will give you that look:
Thank you. The distance from the entrance to sitting room inside of the house will get much longer if I use 3 stories of full foundation height. That's why I wanted to use platform instead of foundations. Anyway I noticed it's unavailable to place a front door on the platform without move cheat. So actually I gave up building the stairs like that.For something like that I'd use the regular foundation and try to put stairs all around it as best I could.
Oh, I meant just one level of foundation. From a foundation to the ground is 3 steps or so. If you put the stairs all around the foundation you'd get a pretty similar look.
I've done it the way you suggested and put lot p!ants in the corners to disguise where the stairs don't meet.
I thought the placefriezes cheat was for the foundation tool. I've never thought to try it with the platform tool. I'll have to try that in my game and see what happens.
For the foundation tool at least, with the cheat active you cannot put friezes on the ground, they must be placed either on a wall, a foundation, or (I think) another frieze.
Sorry for the late reply. Yes I think you're right but will it be possible to build some platform in 3 levels of layers like low 3 steps without cheat? It didn't work on my lot.
I was unable to place a platform on another platform, with or without the placefriezes cheat. I'm hardly a build expert though.
I recently came across a lot in a CC world where the builder had used a regular foundation but used the CFE cheat to make it the same height as a platform for some reason. My sims couldn't get into the building though, they were route blocked. I had to alter the lot to make the foundation high enough to place stairs before they could get inside.
