Close FeatureLine.ByPolyCurve

Hello, when I make a FeatureLine.ByPolyCurve it closes automatically, how can I make it not close it.
Thank you

Can you tell me how you created the polycurve?. If you created the polycurve by “PolyCurve.ByJoinedCurves” node, sometime it is joining the start to end points and hence the created feature line is closed. Try to create the polycuve by using “PolyCurve.ByPoints” node. Another thing to check is to set the script file Geometry Scaling to “Medium”.

thank you very much, it was to put the Scaling to “Medium”, I had it in extra
