import/rebild/subdivide surface

Hello,

I try to subdivide a surface, created in 3ds max into hexagons with grasshopper.

In Rhino I converted it into an open polysurface, sliced it and lofted the curves in GH. Due to te geometry, the loft failed, because the geomety divides int 2 directions.
I tryed to slice it with a horizontal plane but the loft failed as well.

The 2 "MESH TO SURFACE" groups in the script are parts from files i found in other discussions. Unfortunately the hexagon command from lunchbox cannot handle the output brep from the first script.

Do you know any way to bring a geometry like this into grasshopper without rebuild in grasshopper from scratch? This is just a testform, I'd like to replace it when the script is running.

Thanks for Your help
