Planes at points following a curved surface

Hey!

 

I am trying to add rebar stirrups in a curved wall and therefore need planes normal to the curve of the wall to “host” the stirrups. I have added points where I would want my planes, but I cannot get my planes to attach/find my points. Does anyone have any tips?

 

BTW: The green group “Not following curve” is another try which also failed, however in this script used for calculation of various parameters.

Thanks Khasan!

No problem)
