Ok, in 2009 everything worked fine. Since we updated 2010, any and all filled regions (detail component) within my plumbing valves won't appear in the the project. Even the valves that come with Revit, such as the butterfly valve. The round circle in the middle should be filled with a solid region but it all you see is a circle and no fill.
I have tried everything I know but nothing works. In the family, I can see the filled region and it adjusts with the constraints appropriately but still won't appear. I have even tried starting from scratch and still nothing. The one quirky thing I did find was if I was if I changed the visibility settings of the detailed component to show in "Fine", it appears in Fine but won't appear in Medium or Coarse. Also, if I change the element properties and uncheck "Use Annotation Scale", the filled region appears. I have tried applying different view templates, different project templates, VG settings, etc.
So after exhausting ever imaginable option, I decided to post. I need help!!!!!!!
