Has somebody else encountered this?
At some point when modelling a SubD the Gumball starts being totally off when selecting a single vertex.
At first I thought this had to do with SubD toggle between smooth and straight mode, but it is not.
My Gumball is set to World and I have already ran “Reset Gumball”.
Not sure how to reproduce as sometimes it works ok…
Hello- I have not seen this. Can you post that object?

Sure! Although I am no sure if it will come up on your end.
Probably it is one of those things that does not come up on other pcs or is solved after I restart Rhino or copy the object to another file.

I’ve experienced this too some days ago.
This should be fixed in the 8.5 service release candidate. I reported it a couple weeks ago but I’m not sure if the fix is in 8.4.
