Hello, hope anyone can give me support.

I’m trying to model a mooring line fixed, at one end, at the bottom of a lake, and, at the other end, attached to a moving floating pontoon. I could simulate pretty easily the mooring line as a catenary in kangaroo and the moving floating platform. The problem is that i can’t figure out how to model the slack catenary laid on the bottom of the lake, I mean the catenary intersects the ground mesh. I was trying to use solid point collide but i cannot get it correctly done with the catenary. Maybe the solution is simple but i’m very new of GH and Kangaroo2

Please help will be really appreciated
