Curves through Multiple Grids

Hello All,

First time posting here and somewhat new user to GH. I'm interested in creating some 3D lattice/grid structures by flowing curves through the points on 2 separate grids. I have been doing a lot of different experimenting and seem to have some success with the Weave command, but I seem to be limited to a strict Z axis connection of points. The closest success I've come to altering the pattern is using a SHIFT LIST command to alter the point data but it is still not connecting in any other axis besides Z.

From what I can find online it seems I need to better understand how to change the point data of my grids, because that is how the curve is interpreting what order to go from point to point.

Thanks All
