Q: Using points as streching forces

Dear forum,

I'm making a model where I generate horizontal staffs which I want to use as streching forces for a "tensile" surface. I try to illustrate my goal with the following digrams:

1)The staffs:

2)The tensile surface

3)The tensile surface plan

4)The desirable result using the staffs as streching forces to reshape the tensile surface.

Can anyone give me a tip of how to use the staffs as streching forces and how to translate the surface I want to use as tensile surface in Kangaroo?

In the attachment I have the rhino and grasshopper model.

Thank you in advance,

Alexis
