Hello everyone!
I am pleased that there is so much interest in this type of pattern design and will continue to work on it.
I have now uploaded my solution approach, whereby I realized that there must be a relation to the distance of the parallel lines to the whole pattern,
because I only almost made it, I had to dizzy one point a bit. But I hope that this is hardly recognizable.

As I need a dxf file for the cnc milling machine, I had to delete a lot of superimposed lines, or I had to redraw them with a multiline (milling direction!).

Best regards
Franz
