Lunchbox on imported geometry

Hello, does anyone have a script that chen convert imported geometry to a surface? I model my geometry in 3dsmax (i dont know how to model in rhino), and i import it as a obj into rhino then as a mesh into grasshopper. 

Here in grasshoper i want to use lunchbox to create a structure (its an architectural project) i want to transform this mesh into a surface than i will use lunchbox with panels or structure to create the structure of the form (metal structure covered with glass)

Does anyone knows how can i do this? 

Thanks a lot!
