Mirror generic model at specific point

I’m trying to mirror a stair generic model that I created from a specific point with the bakery node “Mirror an Element” and I can’t manage to make it work.
I can’t find what could be wrong especially that I’ve been trying to mirror the Geometry of my element and it works perfectly.
I’m using the last version of Bakery package which is 2018.4.301 and you can find my dyn and rvt files attached.

What do you think is wrong?

In Revit you need a line (2 pts) to mirror.
That Node has an Input called planeList.
Try feeding it a plane or line

Thank you for your help.

I feeded it with plane as you can see in the image but it steel doesn’t work. The plane is made from a point at the base of the stair which is where I want to place the mirror.

I use this to mirror/flip sections
there might be something usefull in there
I’m not into Python yet.
I copied it from
Mirror sectionview without a copy (Python)
