comment Why does ITopologicalOperator2 .ConstructUnion produce a somehow invalid polygon?
@Petr: I added the spatial reference - no change. I think of making a test project I could share. Would that help?

@AHigh: The GraphicsContainer is a casted IActiveView.FocusMap (added to question). Casting resultPolygon to an IPolygon didn't help.

Thanks. I added it to both my source and the question. Unfortunately it didn't help with the problem.

comment Why does ITopologicalOperator2 .ConstructUnion produce a somehow invalid polygon?
@Petr, do you mean without using ConstructUnion? When I directly assign element.Geometry = feature.Shape it does work, as I pointed out. (made that more clear in the question) That's why I think it has to be something with ConstructUnion.

Thanks for the hints. 1.) I changed the asignment to ShapeCopy, but with no result. 2. + 3.) For testing I use a single layer where I select three polygon features. 4.) For testing I directly used the resultPolygon instead of the Buffer output as element geometry, but it didn't helped. And 5.) resultPolygon.IsEmpty is false.

@AHigh: Yes, I do make sure that there is only one geometry type. Thanks for pointing it out.
