Match discontinuous point lists structures both ways

Hi,

I am looking get match User Text attributes between two lists of points. Each of the lists represents an iteration, the first list is the list of discontinous points of a curve network prior to adding the selected curve, whereas the second list of discontinuous points includes geometric changes.

The issue I have right now is that it is easy to match the first list to the second (so match the data in Rhino to Grasshopper), but I can’t seem to find a good way to match the Grasshopper data to the Rhino data. I need to do this so I can get some of the User Text keys and values from Rhino and some from Grasshopper.

Okay, found the solution now that it’s not 30 degrees inside.

Here’s one method with reverse closest point matching:

And another option matching points afterwards:

Both appear to perform equally well in this example case (6 ms for each solution).
