External curve of a curve

Grasshopper

Hello everyone,

I am struggling to find a way to generate the outside curve of an existing curve. My goal is to generate the “outside” footprint with the original footprint, omitting the holes made by the fingers.

I attach a picture of the original curve, the same curve with a rebuild (witch as you can see doesn’t work), and the deserved curve painted over the screenshot.

I don’t have any idea of how I could do this in an automatic way, so any help will be really appreciated.

Thanks,
Dídac

Try divide curve and use points to create convex hull

You can also try to fit curve, something like this:

it needs tweaking the fitness factor to your likeness.
