How to extend and trim

Did you try Use snapper transformer​

Hi @vijay16vali​ 

As @f.kemminje​ wrote above, the transformer Snapper is good tip to extend your line.

For trim action you can split the line with LineOnLineOverlayer and calculate the lenght on lines.

After you can filter the microlinies using the transformer Tester.

Thanks in Advance,
