Problem with merging curves/surfaces

Hi guys,

I’m trying to join some closed curves in Grasshopper. They don’t all overlap, though those that do I’m trying to join. I am currently trying to do so through boundrary surface nodes.

When i join them different lists are constructed, although i want to be able to get the total area of them all, and i cant do that when the lists are split as they are. I’ll attatch a picture to illustrate.

When i only join two curves I’m able to do so. Although when i connect a few more some problems come up.

Thanks for the help. I’ll add anything you might need if you wanna help.

Goodday.
