Brep Join and Solid union

Grasshopper
1

In my project, I have some closed BREPs. I tried to make one solid BREP, but I don’t understand why it doesn’t work correctly. Could somebody explain what’s wrong?

Without looking at your code….try flatten your inputs.

Tolerance set to 0.0001.

I would flatten the input curves of the multipipe component. If the curve endpoints coincide, you get one single mesh / subd and don’t need to boolean union anything afterwards
