quick and useful
- _blendEdge as @encephalon mentioned
- use other tools like xnurbs (as Plugin or via plaxticity)
- use parasolids (kernel) fill function from software that is based on it (siemens nx, plasticity, onshape, solidworks, …)
- do it with subD in rhino
- poor rhino backup: use _netWorkSrf or try _patch
- check out rhino WIP / Rhino 9 _npatch
vanilla rhino
my vanilla rhino ( rhino only ) solution would be to find a surface / patch layout, where each surface stepwise reduces the complexity of the transition.
And all surfaces are (or at least try to be) either convex or concave in one direction (U,V).
- untrimmed edges are better then trimmed edges
- avoid rational surface to match to (use deformable option in revolve)
- _matchSrf is painful but the only tool that will make it happen, use the pull option for edges that trim other surfaces later (like the edge of the green surfaces, that trims the blue one)
- if you want to get really nerdy: you can combine _matchSrf with history. (refine = no) and massage the CV’s of the surfaces.
not claiming this is a perfect solution but should point in at least a possible direction:

@skysurfer - I hope this post is rhinophile enough ;-D
