# Curve to extrude through a surface's Norm vector non planar

#1

I have an interp curve on non planar surface ( like ring ), and I want this curve to extrude as surface normal vector direction,
how I can make it ? any command with this function ?
thanks

#2

extrude bothside to get intersection to surface, because after I blendcrv, I just realize my blended curve is not on the surface ,

can we make the curve is on the surface after we blendcrv 2 curves ?
thanks

Hi Cliffonde - use Pull to make sure the curve is on the surface and then the `Fin` command (Surface menu > Extrude curve > Normal to Surface)

Thank You so much Mr.Pascal
