Hi Guy,
I have some curves as below and how to get internal boundary from these curves
Thanks

The curves don’t touch each other? So you need to Extend Curve and then find intersection points. However, your curves are not all co-planar so they don’t all intersect. You can project them to a plane and then it will work:

Getting rectangles from this is another step… Several ways to do it but it’s a little more complicated and they won’t be where you have them now.
