# Geometry Nodes: Points and Vectors [duplicate]

i want to create lines (edges) connecting the vertices of two grids (what i'm really trying to do is have an array of parallel vectors) with geometry nodes.

I thought i could

1. take a grid and convert to points
2. instance and move it (set position)
3. Get the position of each point
4. subtract the positions of the two grids
5. be done

But somehow i cannot find a way to convert points to vectors and vice versa

I think i am a little bit confused that a geometry of points is handled differently from a list of vectors (if there is something like that in geometry nodes). After all a point is just a set of 3 coordinates - i.e. a vector.

Also blender shows that the output of vector math/subtract is not compatible with the curve line input ( i guess it doesnt like having more than one vector as input, right?)

I guess that one implicit question is: how can i handle a list or array of vectors in geometry nodes?

Thank you for any help!

1. Extrude the vertices of a grid in one direction with Extrude Mesh.
2. Remove the excess geometry with Separate Geometry.
