URGENT!!!!!!!problems with kangaroo (form finding) and lunchbox (panelization)

Hi guys,
I have two problems with kangaroo and lunchbox that I can not solve.
I want to create a structure through kangaroo and later pannelling through lunchbox. My problem is that with kangaroo I have to redefine a mesh and when I try the form finding, boundaries doesn't work corretly (see photo with numner 1). The edges of the mesh are not well defined and can not get a perfect surface.

Finally, found a form with kangaroo, I try to use the patch command to create a new paneling but I have a problem with the surface untrimmed and trimmed because lunchbox detects an area different from the patch command (i try to use "untrim" command but it is no possible to change the result).

How can I fix these problems?
It 's just follow these two steps in this way? thank you so much guys

Hi. I had a chance to look at your file and I almost finished it, but need to go right now and will send you your file tomorrow. But, you can try some things. Check which mesh you used to get mesh-lines and the geometry input in kangaroo. I understood that you want to have a boundary of you simulation be more stiff ( maybe I'm wrong ) so you input rest length limitation as pre-tension, but to all springs. Separate spring generation for naked edges with a bigger stifness and interior edges - with smaller stiffness. After you get ff-mesh, use mesh points for patch, spans = 50, flexibility = 100+. It should work( it worked for me ). So I will finish and send a file tomorrow and and I want also to cut your panels with ff-mesh boundary.
this is a nice way to make paneling, but not the best, obviously. I would look on generating panelization tool in kangaroo to get better shape approximation and panel distribution. Ok. See you tomorrow. Hope it will help.

Hi Victor, thanks for your tips.
In fact, I also thought I reverse the logical sequence, or use first lunchbox to create panels and then after use kangaroo for form finding.
My goal in fact is this:

1) have starting area;
2) creation panels (with lunchbox);
3) find the form finding kangaroo;
4) the shape find, being able later to planarize the panels (such as hexagons, squares, etc. ). I tryed but doesn't work - maybe problems with rest lenght or stiffness-

This is the best method I think I understood.
I tried this but I always have the problem of lunchbox that, from an initial surface "cut", I always that "untrimmed" ...you can see this problem with the attached files

I can not understand how I can do to solve this simple exercise.

Thanks for your help
