A reader flagged this issue for me.

Word 2016 for Mac: I can't cut-and-paste an image from a vector drawing program I am a scientist and I routinely create images in a vector drawing program called ChemBioDraw. In past versions of Word, I was always able to copy these images to the clipboard and paste directly into the text of a document. With Word 2016 for Mac, all I get is many lines of gibberish code and no image. Am I missing something, or has the ability to handle vector graphics been eliminated from the program? FYI- a friend of mine who does design is having the same problem with a CAD program.

A quick search of the ChemBioDraw support forum highlights several threads that appear to be about the same issue.

I'm a new user of ChemDraw, and I have tried to copy/paste my structure into word and just end up with heaps of text like this:

With the rather unhelpful response

Currently our products are not supported with MS Office 2016. We plan to support MS Office 2016 for the future release/update.

The only thing I can suggest in the meantime is use the "Paste as PDF" functionality, this should allow display and round-trip editing.

I did a quick test with ChemDoodle and there don't seem to be any issues with this chemical drawing programme.
