Hi. I just have a problem. And I do not know how to show stairs in minecraft with the / fill command in the right direction because they always twist. Now I wrote that in a command block:

/ fill ~ ~ ~ ~ + 10 ~ ~ oak_stairs

And would now have to turn it quasi. I play the Bedrock Edition or Win 10

/ fill xyz xyz minecraft: oak_wood_stairs [facing: (west / east / north / south)]

Or something like that, look on the internet for facing in minecraft, at facing I'm sure!
