i have many lines with different id inside the polygon ,some of lines crossed the polygon from both side and some not as picture .

 

overlaps equal 1 in any lines intersected with polygon even if it is intersected from one side or two side

but i want to extract only the lines that intersected only from two side .

i used lineonarea with tolerance automatic but the output overlaps =1

i used spatial relator but always i got the same output with any transformer overlaps =1

it will be nice ,if someone advice me how could i know which lines intersected two times or one time

i used tolerance Automatice but no changes in output

 

Thanks in advance

@gogopotter90 SpatialRelator should be able to tell you if a line crosses or overlaps a polygon. Check the FME User Documentation on Spatial Relations Defined
