I would like to identify 360 degree loops formed from a polyline and its attributes. ID's are the same but should only occur on 3 or less edges and not 4, forming the "loop".
Below image gives a clearer overview.
How will I go about identifying these issues?
Thanks
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.
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.
Correct me if I'm wrong, but the ID: 02 lines don't form a loop, do they? The connecting piece is ID: 01

Yes, this is correct
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"?

Thanks for the solution. This solution works quite well.
