As you can see in the video, I can fillet the corner for the curve in Rhino but not in Grasshopper.

Hi @Wiley
Hopefully one of the bigger brains will chime in as to why it isn’t working, but here, exploding the curve and then re-joining fixes it. This could indicate that maybe there was a tolerance/very far from world origin-issue when the curves were joined - as the curves are 500 meters from W0,0,0.
