VICODynamics: a particle based Soft-Body physics Plugin

Hello
I can’t figure out how to work with 2D limiters (what needs to be specified in the Plan origin and Plane Normal)?
I am making a 2d platformer, the player releases a web and uses it as a bungee, could you describe the optimal algorithm for implementing such a mechanic? Perhaps someone has examples, I will be glad if you share them.
