Boundary Surfaces loses values


I put 6519 curves to Boundart Surfaces component.

But it’s result is 6426 trimmed surfaces.

Where gone the 93 surfaces?? :thinking:

Is it because some curves intersect?

How can I resolve it through Grasshopper not just finding one by one ?

Thank you!!


Sometimes you get surfaces between 2 or more curves, that’s why you’re getting less surfaces than the input curves. If you want to create individual surfaces from all the curves, just graft the input.

If the Boundary Surfaces component can turn two curves into a single surface (by using one as a hole boundary), it will. If you want one-to-one conversion you’ll either have to graft the inputs, or just plug the curves directly into a surface parameter, that’ll perform a one-to-one conversion.
