Although I don’t think this issue is unique to Kangaroo since some testing revealed similar results using GH mesh welding, weaverbird, and manual Rhino modeling, I figured you folks work with meshes regularly and may have some insight.
Lately, I’ve been noticing naked mesh edges/points arising in unexpected areas after combining primitive mesh faces. I’m unsure why this would be the case, as I have used these methods before without issue …
Below is a sample for consideration - both a GH model and an internalized Rhino version.
