Hi mdesign, well whether that works in the future or not depends on whether Rhino supports it or not.

Do you have any earlier versions of Rhino on that same machine? What happens if you try to copy/paste from Rhino7 into Rhino v5 or v6?

Getting a flat result may mean something like Rhino v7 is putting PDF format into the clipboard only and isn't responding to any requests for a v5 or earlier 3DM format type.

For the copy/paste from Rhino to MoI to work, Rhino needs to respond to requests for Rhino v5 3DM files. If it doesn't respond to that then that's the problem.
