Open closed curve

Very simple question but couldn’t find the solution. Suppose I have a fully closed curve, how do I delete the edge between two of the vertices so that it becomes an open curve? Every time I delete a vertex it just connects the two vertices next to it to eachother.


there is shatter component in grasshopper using points

For PolyCurves you can simply select a segment by Ctrl+Shift+Clickand then delete it, and for single-curves, you can trim a part of the curve to make it open.


It turns out to be a PolyCurve, thanks a lot!
