Hi Friends,

I want to use this intersect sample code of arcobject vba to catch duplicates in lines and polygons :

1:The problem is that when I apply it on the same layer to find duplicated features it doesn't work, while through toolbox> overlay> intersect it works properly. Here is a sample image:

2: Do you have any other workaround for catching duplicates in polylines and polygons, I thought about a: TopologicalOperator::simplify, b: RelationalOperator::equals,  c: finding centroids and midlines, but I don't know which one is a correct solution.

Note: I don't want use attribute table to remove duplication, I need a geometrical solution.
