Self-intersecting curve not recognised

Grasshopper
1

Hi

I have an issue where I have a self intersecting curve which isn’t being recognised by Grasshopper. If I run ‘selSelfIntersectingCrv’ in Rhino it returns an error. But in Grasshopper, no points are returned nor is it invalid. What could be causing this?

In GH, you are using Multiple Curves intersection (MCX), where you only have one cuve. Maybe try Curve/Self Intersection (CX)
