How to fillet edges of solid union intersections

[lander (CAD CAM CNC)]

haha, maybe now that you got me thinking of that, it must’ve been subconscious at the time

I made a sample, I hope it shall suffice @Joseph_Oster You’re right I should have shared a sample earlier.

I still need to study @DanielPiker 's post file though.

Ok this is really cool. I’m still trying to understand deconstruction, lists, and the culling part, but I’ll give this a try.

finally putting some energy into this but totally lost:

too bad this thread doesn’t have the answer:

How are deconstructed brep edges organized?

Hey, I need to retrieve a specific edge from deconstruct brep. But as I marked the edges up with their list positions, using the dot component, I noticed that their numbers/positions scrambled when I edited the rhino input geometry. So I wonder what the logic is behind the deconstruct brep component, and if I can get consistent lists out of them. Thanks! Pelle

yet another dead end:

Deconstruct Brep questions

What is the rule when deconstructing breps? What is the order in which the faces/vertices/edges are indexed inside the list? Can I rely that on similar looking objects the order is the same? – or the order is based on the global coordinate system? – the local coordinate system? Thanks in advance.

this plan not really working out, yet:
[Deconstruct Brep] – Edges → [Sort List] – Sorted Edges → [List Item] – Selected Edge → [Fillet Edge]

…

Filter Intersection Edges:

• To specifically target the edges at the intersection, you may need to compare the edges of the original solids and the union. Edges present in the union but not in the original solids are the intersection edges.

still cant figure out how to filter the correct intersections:

taking break bbl…

imma feed this to AI n’ see what happens:

similar, but still not seeing solution:

Fillet Edge failing on (simple?) edge

Hi guys, I am trying to fillet an edge on a closed Brep (see pic). For some reason the ‘Fillet Edge’ component is failing and I can’t figure out why - it seems like quite a straight forward fillet. Please see the GH file here: Fillet_issue.gh (20.0 KB) [Fillet Edge Failing] [script pic] I have tried doing it manually in Rhino and i get the fillet I want, although it does not leave it as 1 solid body. I also need to be able to do the fillet parametrically in GH, so doing it manually is not…
