Generating XYZ coordinates off of surfaces

Greetings.

Is there an easy way to generate XYZ coordinates from surfaces?  In my situation, the X and Y coordinates lie on a fixed grid, but the Z height varies across the surface.

In the attached example, the surface is named "Surface-Knit1", and the X and Y coordinates are the centers of each of the small circles in Sketch7 (bottom of the feature tree).

I've got many surfaces like "Surface-Knit1" but the grid like Sketch7 will always be the same.

Ideally, I'd like the origin to be based on Coordinate System1 (also at the bottom of the feature tree).

Thanks,
