How can I retain the model tree/layer structure when I create a new 3d pdf from a Rhino file? The 3d file does have a model tree with layers, but they are all called “node” and the actual names of the layers from the Rhino file are buried 3 levels down sometimes. When I looked at tutorials on the website, the layers from other CAD software transport without problem. I would like to be able to do the same with Rhino files because they can have a lot of layers and it is not easy to change all the names manually.
