Hello Karsten

I had to work hard to understand the mechanism of selection for
connect Blend Node
now it's works finely............

I must say it has a great performance
Grasshopper even has a tool so wonderful-
Could you add (Go Continuity ) in the feature into it's Node ?....

I also ask you, if the board surface is not a single board, just
Click in sequence the naked edge?

I am attaching a small example of the beautiful performance obtained
combining it to Boolean Intersect Node
in the coming days continuing my exploration
You will definitely ask more from you

Best
