hai.my reader was 5 .las files.i want to create a outer polygon for the .las.it will created but that is only one polygon.i need to create a each .las each polygon for my writer.

Hi,

Enable the format attribute "fme_basename" from first to last step in your workbench and use fanout option based on fme_basename attribute. You will get 5 files as output with the same name as input file name.

Hope this helps
