Firstly I'm sorry for this question which can look casual but i try to find a solution everywhere without success.
I've a project of making automaticaly stairs between to surface.
In order to do this with visual scripting I've to select two points of the two floors. Like this in the screen.
So i want to know if a node exist which give us coordonates of the points where we click. I try some examples give by Allplan and it look like it work because we can place an object where we click but i didn't find the good one.

Thanks for your attention

Have a good day
