I have a list of points which I want to connect to lines. But one line should contain only points with a specific value in a field. At the end I want to have multiple lines in one feature class.
If you tick the Group Processing and then set the Group By to the field that holds the value that will only create lines from points with the same value in that field
Just be sure that the LineBuilder gets the points in the order you want them to appear in the line segment. You could e.g. use a Sorter for this, if you have an attribute that indicates the vertex order.
