URGENT: how to divide curve geometry output of a kangaroo physics model in to 2 directions

I am trying to create a gridshell structure with kangaroo form finding technique however I am stuck with creating laths of the curve geometry output. I am looking for a way to divide the diagrid curve geometry in to 2 groups of perpendicular curves, (as perpendicular I mean just the 2 direction that they are in the image) and then loft them and make the timber laths.

How can I divide the geometry outcome in to 2 different groups of polylines ?
