Trying to apply gravity to a planarsrf

[beemarie]

Trying to do something I think should be simple in grasshopper, but having no luck!

I am hanging a planar srf between two lines and trying to apply gravity to the surface to create a drape effect. Below is a screenshot of my definition. I don’t see any error in it, but still the planarsrf will not hang naturally, it stays stiff.

Can anyone let me know what I’m doing wrong? Would be much appreciated!!

nice pixels, please also post the gh file

at first sight it looks like the Kangaroo Line Length goal is applied to the naked edges, which are also anchored?

I guess something like this, where you specify a final length as multiplier (>1) of their initial length if you want it to somehow drape:

consider also that the naked edge → points you are anchoring are all these:
