Extrude multiple curve direction normal

Hey guys, I can’t figure out how to extrude a set of curves outward based on there normals.

Is this possible in rhino?

I want to extrude all those small circles outward.

Hello- you’ll need a script, or Grasshopper of this - here is a gh that might help.

Hi Pascal,

Thanks for the help! Only one problem is some of the curves or out and some of the curves go in, I flipped the dir but doesn’t change the normal direction.
