I'm still working to understand the Houdini workflow and struggling with what has been simple in other node-based programs I'm familiar with, such as Grasshopper.

I have two groups of points, and would like to connect each point from the first group to a point in the second group, as such:

group_1_pts -> connected to -> group_2_pts

Such that I could produce something similar to this (created in Grasshopper):

Here is one way.

you just need the same ids for the pts and the add node will connect them accordingly

Works like a charm! thanks for the help and including the file -- really helped to find how to use the attributes added via the Enumeration node.
