algorithmic modeling for Rhino

Flipped / reversed normals

Hi, I had just started to learn Grasshopper this weekend.

And I've tried some definitions, some of them have the same problem, the normals seems to be flipped. It's noticed when the Weavebird's Mesh Thicken or even using offset surface is applied, some of them went inward other outward.

Anyone knows a way to make them have the same direction? Maybe comparing one cell with the side one and making a normal average.

Thank you for your attention!

uuh, there we go!! Sorry for didn't reply before, I was trying to go further with you 1st answer. I had tried to find a way to identify the face orientation to then flip it, but I have an insignificant advance.

And I just found this discussion http://www.grasshopper3d.com/forum/topics/normal-directionagain-sor..., however my small knowledge in icons couldn't help to reproduce the full definition.

Thanks for your attention!
