Sweep across multiple line segments

Hi PEC
Thanks so much for your quick response, and the video provides me with a solution!

I still do wonder whether something has changed in Shapr3D (or I’m misunderstanding the sweep function!). In the past I used this video to achieve the same effect:

In that you can see that the spiral is made up of multiple line segments, however, after applying the sweep to each segment the new solid body seems to be able to be stretched as a single entity. I’d be interested in your comments?

Many Thanks
Fortuna
