I have a model with a fill surface, when I open it's fine, when I ctrl-Q my fill surface fails. I open it to find the problem and the patch boundary selection box is empty. So I reselect, it ok and it's fine. Then I ctrl-Q again and same thing all over again. Anybody seen this, heard about this, any suggestions.
And no I can't post, wish I could. And I'm running 2012sp2.
Thanks in advance,
