so for example select feature class one with 1 and feature class two with ID 1 and build apolygon and then a loop two ID 2 and so on....otherwise FME will build too much unnecessary polygons because lines are overlayed...
Thanks

Hi,
I would try the polygon builder or area buldier with a group by (ID) if that results in uncorrect polygons, try to remove duplicates (geometry/ID)

i want only one run and then loop it...means select from feature class A feature with ST_ID = 1 and select from feature class B feature with ST_ID = 1 and create a polygon with the AREA Builder then take the features with and ID higher (means in this case ID = 2) and do that for ca. 1300 features....i need a loop....but how can i do that ?
Hi,
I'm not sure why you need a loop. As Itay mentioned, if you specify ST_ID to "Group By" parameter of the AreaBuilder, it will create polygons separately according to ST_ID, at one run-time. A resultant polygon having ST_ID = N will be assembled from only lines having ST_ID = N.
