Revit 2018. Buildings are see through on elevation views

[Anonymous]

Good Day,

I am currently working on Revit 2018. When i go into elevation view all of my views are transparent. I can't see everything inside the buildings, only things like pillars, windows and foundations behind the Top Surface.

I have checked all settings and none of the walls are set to transparent. I have also checked the settings with other projects and none of them have the same problem.

Any help would be greatly appreciated.

Turn off any CAD imports for those views.

Thank you very much, can't believe it was such an easy solution.

How do you turn off CAD imports? Sorry pretty new to Revit.

Thank you! 

But WHY is this the solution? The Items that showed up are not the CAD items?
This is a glitch that needs a fix...
