Hi Matthew,

If you extrude the Curves before the Surface Morph then you can get the Extruded Surfaces to Morph to the surface without having to workout any Normal Directions.

Now I get this... Any ideas why?

I found that if I sweep to create the surface it is fine, but if I loft it it turns out like it does above... Weird.

Extruding it before morphing it def makes it extrude tangentially, which is what I wanted so thank you again Danny !

1) The UV directions for the Loft are 90 degrees out to the UV directions of the Sweep method. So you would need to alter your definition accordingly.

2) Glad to here it, you're welcome.
