How to obtain Mesh edges, points and relative face normals

Hi,

I have an open mesh and using mesh edges I can join E1 to obtain a polyline that resembles the outter edge of the mesh. After which I use Control Points to get the XYZ coordinates which are indexed anti-clockwise.

I have also used deconstruct mesh where I am able to obtain all the face normals (I believe they are the face normals and not the vertices' normals?)

The problem I am having is matching the list of Control points coordinates to their relative face normals.

Another way to put it: I would like to obtain the 6 coordinates (xyz points, xyz normals) in an sequential (clock or anti clockwise) manner for only the outer edge of an open mesh and store them in a list of some kind.

Can anyone help?

Hi,

so using Face Normal and Closest Point I have obtained the face centre point at the edges of the mesh and the related index.

How can I combine the list of indexes given and look up the related normal from another list?

In other words, given two lists, how do I look up the value from one list (the list that contains indexes' as values) from the another list (the second list contains the normals' xyz coordinates)?

Hope this makes sense.
