Hello ,

i have some points at the same line

each two point has the same attribute .

i would like to connect each point that has same id together

So I think I can use line builder with group by id .how

but how to connect each two point without the line intersect with other points ?

as my phone ,

point 1 and point 4 has the same id

but if I connect 1 and 4 together so it will create line intersect or overlap on other line between 2 and 3

2 ,3 has same id

1,4 has same id

what should I do to create line between 1,4 and other between 2,3 ? The line should cross but not intersect because I would like to use network topology calculator later .

If you are using a LineBuilder with a GroupBy, then the line geometry it creates will connect all the points in each group. All the groups are separate, there will be no intersection that a network topo calculator could recognise, except if two groups share the same point.

If you want to 'clip' out segments of these lines if they pass other points, then use a PointOnLineOverlayer, all points vs all lines, on the lines add a list of point IDs they touch, and then on the output exclude any new segmented lines if that list doesn't contain at least one point ID from its original group.
