Is this because I’ve swapped Named Positions from what was active when the snapshot was created?
But it keeps asking regardless of how many times I switch between snapshots.
And I can’t see how to add Named Positions to existing snapshots. Choose Edit Snapshots only brings up a dialog which says “delete snapshot data” in Rhino 7:
Ok, I clicked “do not show this message again” and now, even if I click save on my Snapshot and go through the four clicks required to save (and one of those four clicks in the add/edit panel I was looking for previously), but it does not save.
How do I get that message window back, because apparently you do need to click yes on that bloody window every time you switch snapshots in order to save it… 
thread very carefully with Snapshops. It was never built right, and I recommend you only use it in a disposable copy of your file. Lots of problems reported, never addressed AFAIK: Snapshots issues
Oh, no. It’s blocks all over again! 
So, Named Positions and layer visibility juggling it is then. Do you know of any stability issues (other than the added hassle) with that?
(And the fact that my client who downloaded Rhino won’t be able to switch between concepts as easily… and mayhaps put a dent in his willingness to adopt Rhino…)
