I am searching for a transformer where ITopologicalOperator.ConstructUnion in ArcGIS..

Hi @kanthsri74, looks like it's the name of a method from ArcObjects API, but I don't know how it works exactly. Perhaps does it merge the input areas which touch or overlap each other to create a single area? If so, the Dissolver transformer might help you. Otherwise, please explain how the method should work for the input geometries.
