That’s just a piece of a larger handcrafted wooden frame of a chair. I know that the curves are not the most precise work you’ve ever seen, but I’m converting it in the end to T-Spline surfaces, so that takes care of the problem.

Here is the frame as a whole with the problematic meeting spot where the three pieces meet.

I tried bridging it with T-Splines itself, but it’s restricted to only two face groups.

I think I’ve wasted all the possibilities my Rhino knowledge allows me to, to get this to work seamlessly.

If anyone has any idea how to bridge these three directions together at once, please share your process.

I’ll have to go about as @John_Brock and @Lagom suggested. Thank you.
