# How to match Z coordinate for vertices from two different objects that share same X and Y coordinates?

I wonder if anyone know a tip to match Z coordinate for vertices from two different objects that share same X and Y coordinates ? I work with very complex objects (a landcape and a road) and i need to sew them together. The road is just a part of the landscape that I intersect with a volume, so I could sculpt to smooth its surafce. While sculptind, I locked the X and Y axis so the points are surimposed on the Z axis between the two objects. The idea now is to vertically match the landscape vertices with the one of the road.

I'm not familiar with the geometry nodes or python scripts, but i guess i could use one of those to do this job ... I have thousands of point to translate on Z axis so if anyone know a way to keep me from doing it one by one I would be very grateful :)

Thank you very much for your help

• Just use the node Raycast with a Ray Direction of $(0,0-1)$ (from the terrain down to the street). Alternatively, it should also work with Geometry Proximity, but that basically depends on your mesh. Mar 20, 2023 at 10:22
