Hi @gogopotter90

Did you try to use the transformer LineonLineOverlayer?

Thanks in Advance,

Danilo

@gogopotter90 Pretty well all FME topology transformers require the topology o be 'clean', which includes removing overlapping lines - in this case using the LineOnLineOverlayer as @danilo_fme suggests.

Hi @gogopotter90,

In the TopologyBuilder, please set the parameter 'Advanced - Generate From' to 'End Nodes Only'. This should prevent the cleaning step of topology building that is creating the extra nodes. This option is useful when you have datasets in the which the lines deliberately cross or overlap.

i think generate from did not exist in fme 2018

is there any other option should i do,thanks for helping

i used line on line ,it creates the same extra point also ,and i have also crossing lines it creates nodes at overlapped lines but could u explain to me if i used line on line ,how could i create from to node because i see this option only with topology builder .

but the only difference that in topology builder clean yes ,it gives the small line overlapped two id of both of lines intersected in extra node ,but line of line it gives only one id .

i tried also using line on line group by id but it does not create any nodes at intersected lines but output line that exactly what i want bcs i used group by id but i need to create from to node without extra nodes

by using intersector group by id instead of lineonline then point on line transformer

so each line is properly noded then i tried to use topology builder again it gives me the same problem

Do you have suggestion what should i do to create from to node

thanks for helping

In 2018, setting Assume Clean Data to Yes should also prevent the cleaning step, and avoid the line splitting.

i did it already assume data clean ,it creates the extra node but the short line after splitted has two id from splitted line

Would you mind sharing a sample of your data with me? I would like to reproduce the problem and see if I can find the reason for it. You can send it to me privately - - if you wish.

thanks for ur message but unforunately ,it will be hard to share the data,but anyway thanks alot
