Actually, what you show there in the screenshot looks to be the correct and current expected result.

Right now the Silhouette command does not create duplicates of edges that are silhouettes, it only calculates "brand new" silhouettes that are internal pieces of curved surfaces.

The reason why is to avoid making duplicate curves when using it for AI format export.

The way AI export works, is it exports all curves and edges in the model as curves in the flattened AI file. If silhouette generated copies of edges in addition to the internal silhouettes, it would make it pretty easy to get duplicate curves if you just did a SaveAs to AI format.

I can probably put in an option for whether to duplicate edges that are silhouettes or not though, would that be useful for you? I don't think that it would do anything useful for AI export though so probably that option would be off by default.
