Diagonal stairs and ladders don't work - right?

I'm actually wondering if i may be able to make like gigantic curvy staircase with the platforms but i assume it might get too big due to steps having to be 1 tile at least

ah if only i could have platforms already i have so many experiments in mind

I do be really wanting those though cause there was some builds in ts1 using curved staircase and i can't really recreate the vibe in ts4 yet
