T-shaped surface blend

Hi all!
I always struggle to model T-shaped intersections in Rhino. In this example I need to blend three surfaces to make a smooth joint. Does anyone have an idea how to make it clean and smooth?

These are indeed always a challenge. It would help if you could post your 3dm file, if that is possible. Also, there are some suggestions that may work for you in this aptly named thread:

Hi menno,
thanks for pointing me to that thread, I’ll have a look at it.

I’ve attached an example flie

Hi eddi, I tried your patch solution but it’s not that sweet on the edges, unfortunatley.
Thanks for the useful links though!

Network Surface “networksrf” is a command I see people using quite often for this sort of thing. I’ve used it a few times myself, but it has certain rules you need to follow in order for it to make a surface and I seem to mix that up quite often so I won’t try to confuse you. But I would look at the help for that command or I’m sure there are other videos on it as well.

Yes, when surface should be zebra-clean, then only other surface layout helps (link 1,2), where used command’s for creating untrimmed surface.

just take the outline curves and patch the lot?

Here is my take on this: patch, trim both sides, and blend with handle adjustment.
