Grouping curves inside of a border curve

How can I get to group curves inside a border, the curves are open curves and some of these curves are also part of the border. Thank you.

Saw your question the weekend but was away from a computer with GH so could not test my answer.

I will have to have a think more how you can group crvs that are also part of the border, this may not be possible. Though this should solve your title question.

TQ Matt. I was hoping to get a different result. Attached pls find the 3dm file with a sample of the curves I like to group within a boundary.

Ok Try this, it does not match all the red crvs as some of them are part of the boundary but others are not,so don't know what the criteria is for those curves on the boundary. Internalised the data so not currently linked to a rhino file.

I think there should be some way to get those curves with gh. In rhino, what I did was first to split the curves using the boundary as the cutting object and all the other curves as curves to split. I will then group the curves which are not on the boundary which is what I want. It would be quite tedious to do this each time, so I was hoping to using gh to do this curves spliting/grouping. That was how I got to group the inside curves which I attached earlier in the 3dm file.
