Import Rhino Files with Groups / Layers

Hi there :wink:
I´ve benn trying to figure out how to import Rhino Files into Blender with my Layer- System. I´ve got the Problem that it always splits into single objects without building any groups or building “big objects” with all the files from each layer while importing as .obj.

I can see that Blender “recognizes” the layers, but i don´t get a way to handle it the way i want.

What i would like to get is an import where i have all objects imported seperatly and my layers as groups of these objects.

The only way i get this to work is to import every single layer which takes ages… or to import everything as "big objects (all files from one layer in one object) and seperate this by loose parts which isn´t really a clean solution.

Can anyone help me with this? :wink:

Thanks ;D
