Place object to the base of another

The question is more elaborated then the title. 

I will like to create a plane(directly inside bifrostGraph) wich has the dimension of bounding box of another object and of course will be place at the bottom of the boundingBox(BBOX min in Y axis but will change the axis if needest) 
Now i try in a horrible way. OK the plane is there at the origin it seem correct(look at my screenshot) The problem is that i will like to transfer the dimension to the plane(obviously is a plane so the XZ dimension in this case) 
There is some example somewhere if anybody can helps? 

Thanks

In the special case you have where the input geometry is aligned with the xz-plane, you can use the following approach (copy paste this into Bifrost Graph):
