Hello everyone! I’ve been struggling for several days with the task of sorting points along a combined line, starting from a defined point. I tried several sorting methods from the forum, but they didn’t work for me. Can someone tell how to solve this problem?

Try a Curve.ParameterAtPoint And then a List.SortByKey node, using the points and a Polycurve built from all of the curves. If they go in the wrong order try using a ‘Curve.Reverse’ node first to turn things around.

What is the error message you get on the Curve.ParameterAtPoint node?
You’ll need to identify why that happened.
@Igor.Matyukhin I had a quick look. When I change your Curve.ParameterAtPoint node to work on @L1 for the point input (instead of @L2, which doesn’t make any sense to me anyway?), then it seems to work?
Please let me know if this solves the issue.
I tried to reverse sections of the polyline, but the numbering did not change, because it is tied to a set of points.
@Igor.Matyukhin Seems straightforward once you get the sequence of the curves right

@Igor.Matyukhin I found the issue in your original script (the post from Vikram might still be valid, though): it’s a tolerance issue. The distance of those points causing the null results to the polycurve is not 0, but something like 0.00000123. Therefore Curve.ParameterAtPoint fails for those inputs. When changing “Settings - Geometry Scaling” to large, it seems to work fine for me.
