Delete the view and create a new 3D view see if you can still see them.

thank you, it solves the problem, is this revit bug issue.

3D views can get corrupted after a lot of zooming and orbiting.

I have experienced a similar phemon on occasion.  I don't know how it's caused, but I do know how to correct it.  End session and close Revit. Update Display Adapter Driver through Device Manager. Re-launch Revit and voila!  Problem solved.  

...but, sometimes the 3D view is just corrupted. **it happens.
