Offset curves problem

Hi everyone,

Problem offsetting curves, they go in different way. Tried to flip them with a guide but it didn’t worked.

If you have a moment to help, here is definition :

THANKS !

don’t generate new planes based on the curves alone:

expecially because you already have the original planes used to generate those curves in first place :slight_smile: and they are all oriented coherently
