Can anybody tell me how to import a Rhino 3dm file into Acrobat with the file structure still intact?
I see that Rhino is listed as compatible with Acrobat but I can’t find anything that explains how to get my 3D model into Acrobat with the tree structure intact. I tried simply dragging the 3dm file into Acrobat but got an error saying the file type was not supported or that it has been damaged.

There is a third-party plugin for Rhino 4+ that exports into PDF:
