True, but I’m talking about design surfacing. So it always depends. If the look doesn’t matter, who cares.However cornerblends with singularities (triangular patches) are always hard to match. So at some point you have g0 only. For construction this is satisfying, for design it depends. I constantly create Fillets for manufacturing having g2 connection, at some point only matched g1. Basically Bezier blends with acceleration, moving into a true fillet. This is not a true fillet, as said in my last post, but a compromise between two worlds.
you need to cut and match the green surface, but as I pointed out, this won’t be a good solution in most cases, but it can work in this case. Its Stratos solution, and he proved it works. However as he said. You need to improve blue surfaces.
Here is a sketch. Its more difficult, especially in Rhino, but its the standard approach. I use this all the time, I might share a screenshot later. I have no CAD on this machine.
