In any 3D view the glazing shows up as if it were in front. Even the glass on the back side shows through as a color tone. The perspective or iso is fine but any glass panel shows through. This occurs in the "shaded" and "realistic" settings. It is not evident in "hidden line" or "raytrace." I've explored a number of visibility options to no effect.
Is this a glitch in my software? Something systemic? I don't see any comments or questions in the forums that address this issue.
Try updating your video drivers. Revit 2013 has this problem with older display drivers with some video cards. An updated driver should fix the issue.
I also had this problem and once i updated my video driver it was taken care of - i have a nvida graphic card.
I just updated my Nvidia drivers to a .88 driver number....it was the newest version on Nvidias website. It fixed the "transparency" issue, but caused all kinds of other problems. Revit would crash when leaving the materials dialog box. Embedded "flash" animations/videos in web pages would crash, and more...i just rolled back my driver to the previous version.
So, be careful when updating drivers...the newest isn't always the best. I have an Nivdia 1800m card. The 880m is also having issues at this point. Nvidia is working on fixes...
You can try turning off hardware acceleration in the Revit options dialog found on the application menu (big purple "R").
