Turntable with 3D curve

[OXIDO]

Hello everyone,
We are looking for a solution in which we use the turn table to always make sure the work layer is parallel to the ground. I have managed to get the angles for E01 working but getting the angles for E02 is the problem..



I have placed the problem in a red group inside the Grasshopper file. Hope someone has a solution.

Hello,

Here's an example that I put together.
Personally, I would expect several edge cases that are not covered by my simple definition, but hopefully, it will help you with your definition!

Best,
Johannes

Hello,
Yes, with a little bit of orientation, the definition works perfectly.

Thanks,
