Combine lines to find the endpoint

[sb1102222]

First, I want to combine two lines to be a spline.
Then, I want to find out the endpoint of each spline.
However,I cannot figure out the correct answer.
I would appreciate any advices, thank you.

I want to combine:
Line A+D > New Spline 1
Line B+E > New Spline 2
Line C+F > New Spline 3
Then:
Find out endpoints of each splines.

I want to use Line ABC Endpoint to match Line DEF Startpoint in order to combine two lines into one spline, but the answer is wrong.

Hi @sb1102222
First you can group conected Line then join each group to polyline (not spline)

Grouping Curves with Design Script

Design script definition that groups a list of shuffled curves into loops… [GroupCurves] On the package manager search for tstngwtrs-GroupCurves However the node doesn’t need to be downloaded, paste the below code in a code block and call grpCrvs(crv) def grpCrvs(crv:var[]..[]) { dis1 = (crv.StartPoint)<1>.DistanceTo(crv<2>)==0 ||(crv.EndPoint)<1>.DistanceTo(crv<2>)==0; ind1 = List.AllIndicesOf(dis1<1>,true); bln1 = true; ind2 = [Imperative] { …

secand get end point of each poly line
@sovitek
