Hi Kraus,
I found one thing to question about the geometry, but i will have to present a case and question to Michael to ask “WHY” it is behaving that way. I couldnt figure it out on my own.

If i draw 2 “boxes” or cubes and face them apart and at an angle. I can delete the 2 faces pointing at each other and run “blend” on both open edges of the boxes and get smooth, matching surfaces that will join

Using the “segment” portion of your command, produces a nice polygonal segmentation that looks good. If i delete a segment or a couple, running blend has touching edges blend “differently” so there is a gap.

There us something about the segmented gap we need to see if ai can solve to make clean geometry. I dont know how to analyze the underlying geometry enough to understand why the “gaps”, or even if it is “normal” or unwanted.

Let me present the case in a bit. Juggling right now
