Hi Karsten,
Interesting video and I’ve got a couple of questions if you don’t mind.
The things I would like to add to my nod is how you fillet and blend the Airfoil.
At the moment my method require doing this manually then joining and naming. I would like the blend to be automatic and the fillet to be adjustable.
Your new blend node does it use the point on the ‘A’ curve as it’s peak position?
Cheers have a good weekend.
Barry
