Hi@wendyels

Are you trying to get rid of all "SEQ: 4" if so just filter them or is it that you want to remove the 4th part of a grouping if it makes a "loop"?

Correct me if I'm wrong,but the ID: 02 lines don't form a loop,do they?The connecting piece is ID: 01

You could use an AreaBuilder,grouping by the ID.Lines that form a loop are output as an area,if no loop is formed they are output via the incomplete port.

One possible solution is to use the AreaBuilder with a Group By on the "ID" attribute.Specify a list name and use the ListElementCounter to check for >= 4 elements on the output areas.
