If have an nonplanar surface with a curve on that surface, is there a simple way to create a surface, offset some specified distance, that is perpendicular to that nonplanar surface and having an edge at the curve?
Not sure if I’d work, but just a thought
So offsetsrf of the original surface then pull the curve to the offsetted surface.
Then loft the two curves.
I think what you are looking for is the command Fin - or Surface > Extrude Curve > Normal to surface.
I think that FIN is right. I always wondered what that command did.
totally forgot about that command…
