Thanks a lot, that was exactly what I was looking for !
I can finally finish that d***** spiral staircase

Hi, thanks for your answer.

What do you mean by flipping it ?
The way I see it, it's making 180° with the "Rotate" tool on the red or green axis with the spiral selected as a component, which doesn't work since it's a spiral
I end up with the same one I originally had.

What I meant to ask was, is there any way to "cut" the curved face along the line a drew on it (which can be almost on it, I'm not sure, I suck at math) ? I'd like the bottom of each step to be smoothly aligned on the spiral, if you see what I mean.

Hello !

First of all, I'll introduce myself : I'm a french newbie, so excuse me if I mispell words or if my grammar seems a bit strange

Here comes the problem : once again, it's a spiral staircase...
I already searched on the net for a Ruby script and I found DrawHelix1.3, which is not bad but does not allow me to make a clockwise helix. So I settled on my own to make my oh so difficult spiral staircase, and now I'm stuck. I just can't make a face and a curve intersect properly, and I can't understand why.
Here's a few screenshots, I hope you can see what the problem is.

As you can see, it should form a face, but just isn't working.

Any suggestions ?

PS : Here's the staircase :
