The node does not accept this mesh as input
I am now trying a new approach where I find the (x,y) coordinates of the insertion point of the structural foundation pile. I did three attempts based on posts on the forum Z Coordinate from Topo.
I tried with the Solid.projectinputOnto node which is retrieving a lot of random points with the same (x,y) and different Z coordinates 
The Point.Project is retrieving an empty list
And the coding approach does not work.
