Hey Gunter

“””””” how would I create this surface exactly into a plane:””””””

That is a tough one. I can give some tips with a note…

I have done this by copy and past that surface, then use the edit frame to “flatten” it to use as a base… just have to watch our for any parts of the surface that would flatten badly. Lile fold over onto itself because of it….

BUT…….

You should probably not really be going this route. “Unwrapping” is really more complex. The flatten method still doesnt give you a proper result because it is not really the size it should be. Objects will still stretch and distort (which is what i think you are trying to avoid.)

Manually you can copy the longest curves in the surface in the u and v directions and use “unwrapcurve” command to generate a rectangle to create a surface out of, then manually count points and add the same amount to the surface.

But i have really avoided this sunce doing it a couple times and feeling like i was not really achieving anything.

If flow doesnt get you what you need with more simple base shapes to hit the target, then it may be best to go with placing things in a different way.

Barry has shown a very cool way and with minimal effort you could do quite a few little gems properly……
