We receive files from rhino where objects are created on a material by layer basis. i.e. all objects that are to be rendered with concrete are created on a layer named Concrete etc. I am simplifying quite a bit. see the attached images for an example of the nested layer tree in rhino. We export the rhino file to dwg, then import by layer, which combines all rhino geometry on each layer. This is preferred for our workflow as this is the way we work with other import formats; combine geometry by material.
As in the attached image and .max file, the nested hierarchy of the rhino layers is represented in the layer name, separating parent/siblings by a “$” token.
I am trying to recreate the layer tree just as it is in rhino and move all the objects to the newly created layers. I’m close, this creates the tree appropriately but does not move all of the objects to new layers… only some. I assume this is because layer names already exist or something… but i’m not getting errors.
Any help would be appreciated. Thanks.
Max file. I had to strip out all but a couple faces per object for privacy/security purposes.

This seems to work with the sample file you’ve provided, but it may fail with other scenes.
