+5FME Desktop 2020: How the “dissolver” tool can aggregate the result?
I couldn’t figure out if the “dissolver” tool can aggregate the result without the need to use the “aggregator” tool
In the screenshot below, when dissolving and aggregating according to the “autocad_color”, the result should be two features

Thank you for the input.
Then how can I end up with two features when dissolving based on the “autocad_color” field the same way the “dissolve” tool works in ArcGIS?
Combination of a dissolver (dissolves touching geoms) followed by an aggregator (aggregates features)
+61An aggregate isn't dependent on topology (geometric relationship) where as a dissolve will only operate over features touching. Part of the dissolve is to deaggregate any features. See the second bullet point here: http://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/dissolver.htm
