Playing with code like this can be instructive. The BiArc curves I used have an ‘R’ (Ratio) input so I added a slider (0 to 1) for that. When set to zero, the ‘Angle’ slider becomes useless. I changed the range of the ‘Angle’ slider from ‘0 To Pi’ to ‘-Pi To +Pi’, which means that to work correct…

Thanks Joseph, your last GH file above really got my attention and I knew I had to turn it into something unique that I could print. It didn’t take very long before I came up with this: [2023-08-19_235646] This is my slicer’s sliced view - the GH produces a Closed Brep so there are no errors in t…

Five ribs instead of four? Without your GH code, I can’t tell which version you used (‘b’ or ‘c’?) or if you flattened the ‘Curves’ input to MultiPipe? If you did flatten, be aware that the result is two different breps (SubDs) that intersect each other. I’d like to understand MultiPipe better …

I’ll post the final result - hopefully later today. I used only one curve from c, Lofted it, scaled that, used edges for Ruled surfaces, joined all together, then made 5 item Polar array. I like using prime numbers for geometric arrangements.

So you didn’t use MultiPipe at all? Weird looking thing… With all the parameters I provided, why would you scale it?

The Loft surface looked nice - fairly unusual for sure. But it needed thickness. Offset didn’t work because of all the curvature; scaling worked better. The whole thing is quite small so I doubled it’s size in the slicer. I’ll put that back into the GH file along with some other stuff I think will p…

Fun isn’t it? What happened to @super_mario ? [twist_2023Aug20a] twist_2023Aug20a.gh (29.5 KB) SUnion is quite slow and fails sometimes so it is disabled. Wish I understood MultiPipe better. P.S. This is why SUnion is slow - that busy center is a confluence of round ‘Caps’ from MP. [twist_…

Hi, Joseph I’m incorporating you’re script with an rectangular base rather than original circle, so that extended curve can rest on rectangular base and can act as tensegrity stc. I’m new here but yes I love it here. Thank you Joseph and all. And wondering to use kangaroo to check it as tensile …

P.S. Oops, that was four curves - this is two:
