How to wrap a curve around multiple circles

[Omer_Nuray]

Hello,

I am trying to wrap a curve (rectangle) around multiple circles, I imagine that I could use Kangaroo, but I couldn’t quite achieve the result I wanted.

Can anyone help, please? Thanks in advance!

For what you illustrate with straight lines between the circles, I don’t think you need to use Kangaroo - you could just divide the circles with many points and take the convex hull.
For more vacuum like wrappings, this thread might be useful

Here’s a version using 2d pressure to do a vacuum form which pulls the circles together [wrapcircs2] wrapcircles2.gh (23.2 KB)

Thanks a lot, both of them helped.

Appreciate the help!

Minimum surface tent

As expected, it was quite a bit more work… but worth it if that’s what you want? See white group labeled “Connect Line Segments with Circle Fragments”: [Minimum surface tent_2022Sep29e] Minimum surface tent_2022Sep29e.gh (28.0 KB) NOTE: Some of this code (seam alignment) could be skipped if you had created the circles consistently, preferably using GH.

Is there a way to grab that boundary curve it creates and then push that into a kangaroo solver and bring the circles together as tight as possible?
