Boundary Surface Messes up holes

[Kyuubimode]

Hi,

I have a large number of curves and when I attempt to use boundary surfaces it messes up the holes. The same issue also happens when I bake it into rhino and use planar surface. The only way to not have it mess up is not select a fewer number of curves and use planar surface.

I am confused as to how exactly the boundary surfaces component works. The only solution I can think of right now is to detect which curves lie inside of other curves and graft them so that I can run boundary surfaces for each of them. Is there anything else I can do?

Hello
I have done a tool in Nautilus that sorts curves in DataTree (first curve is exterior, others are holes)

But as you have a self intersecting curve it doesn’t work on one occurrence.

Thanks a lot, this helps achieve what I need. I can model in such a way that self intersections do not occur. Thanks for the great component
