(HELP) Making Polygon (or circle) with vector normal at the specitic points in Grasshopper

Hi, I try to draw polygon at point that extract from surface. However I couldn’t make it out so that I tried a circle by doing ‘evaluate surface’. The problem is that I don’t know why there is two circles came out. Somebody can help me out, please?

Or some can tell me how to draw a circle/polygon with vector normal from specific points, it will be perfect.

How did you do that? I struggled for half days and you solved it in 10 mins !
I owe you again, HS!
So the ‘cull duplicates’ delete the second circle that I had before?

Can we do with polygon , too?

Cull duplicate deletes the doubled vertices. Replace circle with hexagon if you want hexagons
