Surface Union Issue in Grasshopper

[Saul_Meneses]

Hi everyone, I’m currently new to using Grasshopper, but I have a problem I can’t find a solution for, so I’m turning to this forum. I’ve created some surfaces that intersect with another, and the problem is that this intersection doesn’t seem to be closed. I think that’s the issue, because when I try to join them and use the Flexibility plugin to create a fillet between the two surfaces, it only works on one of them. I want to know if there’s a proper way to join these two surfaces correctly.Also, as shown in the image, only point 28 appears to be correctly joined. When I tried to investigate the issue, ChatGPT told me that the other surfaces are not properly touching the upper surface. If anyone could tell me how to fix this problem, I’d really appreciate it.

your pictures didn’t upload correctly, anyway a gh file is 10 times better than screenshots

Sorry, I already solved it. I used a surface made in Rhino and used that one in Grasshopper

I found a solution to my problem. There’s probably a more convenient one, but this works for me.
