Q: How to transform a mesh by using curves as streching forces?

Hey guys,

I have lack on knowledge on using kangaroo and I have a question for you.

I would like to transform my mesh using curves as streching forces so when I can relocate my curves i could change the shape of my mesh.

I tried to use the example from Kangaroo (tensile mesh calbes) but I couldnt create the desirable result.

In the attachment you can see my grasshopper file.

In the drawing below you can see a diagram of my question and the desirable goal.

If my question is not clear help me improve it with your feedback.

Thanks in advance,

Alexis
