Hello Forum,
I’m stuck, I’m trying to find a clean way to get g2 on all 6 edges. I’ve gone through all kinds of combos and approaches. xnurbs will do it, but it’s too jangy. Any thoughts would help greatly.

Welcome to the surfacing nightmare, my friend.
I don’t have a solution for this, but here is some insightful reading :

Hi Jeff - I might try something like this -
But, I rearranged the existing surfaces quite a bit, to get them flowing a little better - here’s where I left it, you can see the point arrangement is quite modified on the right hand surface especially.

without a perfect result - a fast approach - kept the giving trimming
I would try to target a surface Layout like this - build in the order as described:
dark blue - twice
(small triangular parts remain…)
sweep1, rebuild, matchSrf
dark green
_blendSrf
light blue
try a _blendSrf from violet to darkgreen.
or a trimming + sweep2
fix continuity
dark red / brown
Split by isocurve
_blendSrf
some of the dependencies from those surfaces can be “implemented” with history - which will allow to modify the shapes until it looks nice.
this might also require to adjust the trimming
some initial form finding with a xnurbs-patch or SubD might be helpful to get some reference
quite a challenge with native rhino commands.

Thanks Pascal
Thanks for this Tom, what your saying makes sense.
This was an interesting exercise. I messed with it for a while. I found I’d do something similar to @pascal .
If I were to put more time into this, I’d probably merge more srf’s together.
Primarily, that little srf in the top middle, gave me to most trouble, so I decided to split off a piece so the bigger srf below could be 4 sided also.
Isolating it that way would help the development process, and it could probably be returned back to a similar side-count to the original, but this “temporary” side-count would help the flow in the meantime.
If absolutely necessary, otherwise, maybe the whole collection of srf’s can be revamped and networked differently to achieve the G2/or curvature intended.
Thanks, I am currently working on a cleaner, simpler approach for the base geometry to make this all a bit less harder than it should be.

I played around with it some more to try improving my original attempt.
If I were to continue I’d probably start merging a few more srf’s and/or altering a few more edges/seams.
