Unroll and join Brep from branch

Hey Together

I have a bit of a problem with unrolling a Fassade for Laser cutting.
I tried to unroll them with the lunchbox plugin with also setting join to True. While unrolling the plugin doesn’t quite manage to join all surfaces. My question now is how can i join all Surfaces in one branch together

This is how the panels look like, most of them are a bit different from each other.

Have you already tried OpenNest?

Sorry Felix, but I can’t get it to work either. I’m not exactly a nesting expert!
Maybe @Petras_Vestartas can give you some pointers? He’s the developer of OpenNest.

it doesn’t work because lots of the faces are not exactly planar, they have some torsion

You can increase Rhino tolerance by scaling down the geometry:
