Hey Joerg,
Not for lack of trying, eh!

Looked at my CAM software. What we are doing is called a “morph spiral” and its more complex for sure.

It was a good exercise looking at how ai failed with the “more complex” parts of the solve. It definitely highlighted what the “complex” part is. Thats where rubbish was returned

Happy trails….

Hi Joerg,
1 last note. A side note.

Thought about it more and vector programs can do this pretty easily. So draw a spiral then “fit it to another shape” basically.

Just in case you can do that as an option
