Hi Community,

When convert subd to brep, there is extraordinary vertex if we have the wrong topologys. I’m hoping to get some insight on where this problem come from:

1 is it the problem with the grasshopper’s implementation? (e.g. need many codings to make it work)

2 Or, is it like a math problem (e.g. no can find perimeter of ellipse, formula just don’t exist)

Many thanks,
