Thank you for the reply, steal-shelter,

You're very welcome.

Let me know how it goes.

Since I write in a Forum, let me add this for anyone reading along: If the amount of the Normal move is different for each polygon, the shared points (and, with that, the edges) will find a sweet spot among all. Then, the Normal direction is not the final determination of the Polygon orientation. Which means the Normal direction has changed.

Enjoy!
