Normal vector at the midpoints of the elements of a Diagrid?

Hi everyone,
I'm doing a diagrid structure with Grasshopper. I want to find the normal vector at the midpoints of the elements of the diagrid. I tried to find it with the definition that you can see in the attached image, but I can't find the surface from the mesh that I have to plug in the surface closest point. Can you help me,please?

Many thanks in advance!

I'm sorry, maybe I wasn't very clear in the previous post... I would like to get the normal vector at the midpoint of each beam and not the normal vector for each face. Could you help me, please?

Many thanks in advance!

Ok I understand, thank you so much!
If I had the rectangular faces, how could I do?

Many thanks in advance!
