algorithmic modeling for Rhino

finding intersecting closed curves or surfaces

Hey, I'm trying to find which closed curves (or their boundary surfaces) from one of the sets are intersecting with others from the other set.
After I´m able to split each of the sets between the intersecting ones and the rest, I would need to join with lines the corners of the intersecting closed curves as shown in the image attached. I guess after that I could create surfaces from the remaining curves, join them and get the boundary surface I need (last step of the image).
Any help would be really appreciated!

thanks in advance, 
Martina

I'm attaching the file with the curves just in case it's useful

I'm not sure about the blue lines, which seem a little arbitrary, but here is the intersecting area:

Curves are internalized, no need for Rhino file.

I know it was simple but it's really useful! thank you Joseph!
