Translate a list of Geometries to XY Plane

I am looking for a simple way to translate a set of geometries to the XY plane. Is there an elegant way to do it?

Take a start point for each geometry.
Project onto plane node.
Geometry.Translate (by direction).


maybe i missed something simple here but i didn’t find OOTB Project onto plane node, as simple as project a point onto xy plane, the only OOTB node i found is Point.Project, tested but not working

figured out, wrong direction
