Problem with 3D & Elevation Views

[BomberAIA]

3D & Elevation views show the walls & roof semi-transparent. I checked all settings. Could there be a DWG import drawing casings this problem? I'm using Revit 20111 & 2014.. Thanks

I found the problem. I had a DWG imported with a large extend. I erased it and everything was normal.

Next time, instead of importing, try linking cad file, works much better ;)

Read up on Revit and large dwg extents. They're not allowed.

Revit goes crazy with large numbers. Everybody thinks computers are capable of extreme accuracy. This is a total myth. The programmers have to decide when they are writing the program what kind of numbers they will use, and every number format imposes restrictions. The number format in use here is called floating point. Among the many joys of floating point is that it cannot represent every number accurately. Google it.
