How can I move bunch of vertices to the origin of the world properly with Sverchok? Please see the image below. As you can see I am  finding the average value and moving all those verts by the same amount in the negative direction. It kind of works but what I want is to put that torus geometry (one drawn by Sverchok viewer) in to the center of the world based on a the calculated origin of the mesh.

Thanks
List Math average isn't what I would use to find the average vector, we have an analyzer node for that. It expects inputs of Vertices, and employs an appropriate algorithm for that kind of input.

List Math expects primarily lists of numbers, (signified by the type of socket : green ) tweaking the level parameter will not result in returning the average of vectors. This is an understandably confusing situation.
