Newbie questions about unfolding meshes (to not lose your time... and mine ! ;-) )

Hello all,

I apologize for my bad English writing, but I hope it is enough to let you understand my needs.

I wonder if your TT Toolbox can do what I need, and before spending a lot of time learning both Grasshopper and TT Toolbox, could you please tell me if this tool will be able to do this for me : 

I need to transform a rounded surface in triangle meshes, then chose the lines to cut some joined meshes, then to align these ones on a plan.

For instance, imagine a portion (a quarter) of a sphere. I need to plan pieces of this form for laser cutting fabric, in the goal of sewing the fabric to reproduce the quarter of the sphere in real life.
So in abstract : doing "surface to mesh", then chose and align these meshes on a plan to finally make a DXF file with this for laser cutting.

I know "ExactFlat" Rhino plugin, but alas it can stretch the fabric and so it is not what I need. 

So : will GrassHopper + TT Toolbox the right, fastest and easiest tool for doing this ?

Thank you very much for your time and your tries helping me.

Cordially,
Guy
