Exchanging rectangular base with polyline

Hey there,

I’m working on a script to find a funicular form based on this given script. ( [Grasshopper] 0096 Simple Tent + Kangaroo 2 (Slow ver.) - YouTube )
Being relativly new to Grasshopper (and Rhino 6) the problem, I have, is that my outer edges are not on the base rectangle.
They should be a applied by a polyline or the individual points themselves, but I am not able to rearrange it properly.
Is there a way to exchange the base plane?

Thanks in advance and best regards!

It depends how you could make base mesh from your boundary polyline…

Thanks a lot, Kim! That’s working wonders for me.
