Objects Missing in Viewports

[M V]

I have a DWG I linked in from a Revit export and I am now noticing after applying some Vray textures that the objects are missing in my viewports. When I render, then show up in the rendering with their materials applied and if I click in the area they are in, I can actually select them, but they don't show up in any of my viewports. I have tried turning the shading on and off and that has not worked. What gives?

Was this a really dumb question? "Metric to Imperial" gets 18 replies and I cant get one? This is my first week using Max, so I am still figuring some things out. Any help would be very appreciated.

Dear valerostudio,

just close and restart max to see if the problem persists. Some graphic card bug, may be

I found that reverting from the Nitrous Graphics mode to Direct 3D solved a similar issue I was having. With the Nitrous display, AutoCAD blocks wouldn't show up in the viewport unless a modifier was applied to them. Once I switched back too Direct 3D I could see my blocks again.
