Thank you for your efforts on this. It appears this task cannot be completed quickly using standard MoI tools. However, Michael showed a MoI-script that reduces the workload by helping to create the spiral manually.

The exploration of CAM was an interesting idea, though mine was unfortunately unable to generate the required construct in this case.

Ultimately, it seems that performing this task with standard tools is difficult without custom coding. Unless this is a task we need to perform daily, the manual script solution likely remains the most efficient approach.
