I tried but no succes

thx

Francesco

I use a topologyBuilder, test the Nodes for those that only have one element in the _node_angle{} list, and then FeatureMerger with the Edges based on the absolute value of the fme_arc_id (node) and the _edge_id (edge). Those that have a match are dangle, those that have multiple matches are isolated.

Hi

I create the WB that identify the dangle geometry but now I have to go into the loop to iterate the WB several time in order to remove the dangle geo generated AFTER FIRST RUN

can you help me ?

thx

Hi @frsisani, you will have to create a custom transformer to perform the process for removing dangles recursively. I posted a solution before: Looping According to Spatial Data

And this is a new version which implements your approach. The FeatureMerger routes the lines (Requestor) to the "Loop to Input port" if a dangle node (Supplier) exists, to the Output port (i.e. finishes the looping) otherwise

• Creating a Custom Transformer
• Looping Custom Transformers
• Looping with a Blocking Transformer

Thx for your help

I tried to understand the "logic" of loop probably I'm very close to the solution but... not completely.

Attached my WB can you please have a look ?

Thx
