Thank you very much for your response! I see what you explain about vectors, know I have a better understanding of problem that I have.
Yes, I have several vectors for each point, what I am trying to parametrize is a structure as below:
Beams are made by plates following three directions - the one to the center of each collindant polyhedron. And nodes are made from the planes of the faces of the collindant polyhedrons.
So I have the same issue with grouping the vectors for the nodes, as I want to have the anchor point in the vertex and control all the adjacent directions so I can create the node. Maybe my strategy is completely wrong.
So my “groups” would be as marked by the colours above.
I reattach the complete file,
Many many thanks for your time!!
