[LVL ED] Create stairs

[Marcus]

Hello,

I started making my own custom stories last night, and I got this bright idea I'd like stairs, and this is where I got abit of trouble.. the walls. How do I create the walls for the stairs? I've tried abit different things however neither of them really made any sense, I'm just terrible at it, or I'm missing some function in the level editor.

I've tried to find some video, I've gone through the tutorial, and I've Googled it. No match. So that's why I'm here. Anyone out there with any tips? Or anyone aware of a tutorial how to create stairs?

Thanks in advance for any response,
Marcus.
