Opening a Rhino 6 file (.3dm) in Rhino 5

I want to open Rhino 6 .3dm file in Rhino 5. So far people I want to send the file to don’t have Rhino 6. This is a real problem for me, luckily I’m only using a evaluation copy.

If so then just save as Rhino5.

I tried that and it’s opening up in 5 in a strange orientation . As though it was saved with origin and then opened instead of inserted

Solved.I had my "ground plane " on in 6 and it showed up in 5 .Thanks
