Hi I have a feature class containing two features in a polygon; one feature inside the other. I want to subtract smaller feature from the larger so that I am left with the boundary of the larger feature without the smaller one.
Question
Spatially subtracting one feature from another

Depending on how I interpret your question, you may also want to consider the Dissolver transformer.

I would think the Clipper is the transformer to use here. The smaller polygon is the Clipper feature, the larger polygon is the Clippee. It will do a cookie cutter operation to remove the smaller polygon from the larger.
