Retrieving Edge Indices for Fillet

Hi all,

I have an issue I can’t find my way around after various searches. Essentially, I’m trying to retrieve the “corner” edge indices of a brep so I can use that information for a fillet. The problem I’m having is that the edge indices information is lost after I manage to isolate the edges I’m looking for. My latest attempt used finding CurveClosestPoint distances (and points I manually placed) to retrieve the indices.
I attached an example and preview. Hopefully, someone can set me straight on the correct way to achieve this. (144.2 KB)

@HS_Kim, yes indeed, that’s exactly what I was trying to accomplish. I don’t use tree statistics or duplicate data mainly because I don’t fully understand how they work. Would you mind briefly explaining how you used both of them? I see that you branched off from the BBox to find the edges of its top face then used that data to inform which edges to select on the vornoi Brep, but that’s about as far as my understanding goes.

Regardless of the explanation, thanks for your help.
