Here's an example of a basic cable.

Hope that helps

Hello Daniel

Thanks very much for your reply. I have set the toggle to false to view the simulation which is great!!
Do you know why I only see the points and not the actual line? and
In a way it has kept the same lenght both when in tension and when loose..Do you know if it's possible to stretch it??Hope I make sense...

Many thanks

Here's how you can show the lines:

(turn off preview for the kangaroo component itself if you don't want to see the points)

I'm not sure exactly what you mean about the stretching.
If you are drawing the curve yourself then you might want to define the natural length of the springs explicitly rather than linking them to the length of the input curve. Then you would be able to stretch it when you moved the ends.

Hey Daniel,
Thanks for that.
I have attached my files. I am working with tensegrity, ispired by Tristan D'Estree's actuated tensegrity, trying to make this component work. By applying a force to the centre, the two ends of the v should become further apart..
Could you help me with that? I have attched my ghx file as well.
MAny thanks

Hello Daniel

I am currently looking at your waterbomb definition and altering that. In a way , the movement is the same.
Do you know if we can invert in grasshopper? or mirror the mirrored? It has to do with the plane axis but grasshopper only gives either xy and xz.Is there a way to define -x-y??
Many thanks
