How can I unroll this mesh using Grasshopper?

Hi All,

I was about to do a laser cutting fabrication for my model, but I have difficulties unrolling this mesh (as seen on the picture)

Is there any possibilities to unroll this type of mesh using Grasshopper or Rhino?

Thank you for your consideration.

Someone correct me if I'm wrong, but that can not unroll. First, being mesh (to my knowledge there are only components for unroll surfaces) and secondly because it is not a structure with planar faces. How you imagined it would unroll it? anyway, you can simplify to the maximum your design and unroll with Pepakura software.

Correct, this mesh is too complex to unroll. If you manage to simplify it, you can try this little script to unroll it (works with breps only so you need to convert every mesh face to surface). Maybe it'll produce some reasonable unroll (depends on brep complexity).
