I’ve repeatedly tried to connect two surfaces using connectsrf. I’ve recreated the surfaces several times. I’ve tried extrude, I’ve tried planes. Nothing has worked. Every time, I get the message “Failed to create valid extension.”
I’m certain that these surfaces are in the correct orientation to each other, ie that a connection could possibly occur. I’m not asking Rhino to do the physically or geometrically impossible.
Would anyone know why, please?
