Align circles to a plane

Grasshopper
1

Hi folks,

I’m trying to get some circles alligned to my surface, and then extrude them from the surface. I’ve worked out how to distribute them on the surface with the right spacing, and the points for origin for the circles on the surface, and kull the points that sit outside the surface. I’m having trouble getting the circles align to the direction of the surface so when they get extruded, they are in the correct direction.

Thanks!
