Join two surfaces in Grasshopper

[joseph.henry]

Hello,

I am trying to join two surfaces (orange) in GrassHopper after creating a loft (blue) with some curves.
The two surfaces have borders in common.

The brep join and solid union doesn’t work.

Thanks

Your input surfaces have different data tree paths, Try to “Flatten” Brep input of Brep Join component.
