Well the first step is to use a clipboard viewer utility to see what clipboard data types Rhino v7 is putting in the clipboard when you do a copy from Rhino.

It seems that there isn't a clipboard viewer built in to Windows anymore like there used to be.

If you can try some app like the ones mentioned here:
https://www.thewindowsclub.com/windows-clipboard-manager-viewer

the data that I'm looking for is a list of clipboard formats like it should have a list something like "CF_DIB", "PDF", "Rhino v7 3DM clip", etc...

I can cook up a little app that would gather and show this list if none of those viewers seems to do it well.
