Not sure that makes any sense in HOudini, but how do i unify the orientation (normal? ..if any) of my imported splines in Houdini? I'm trying to extrude curves exported out of 3ds max and imported in Houdini 16, but when extruding, some extrude one way and the other extrude the other way (see pic). How can i fix that please to make them extrude all in the same direction?

Cheers,

A.
