How to turn off the AutoCAD line drawings seen on a Revit rendering

[octavio2]

I made a 3D camera view  of a floor, where you can see the floor in 3D which includes the columns and ceilings, etc.  However, the 3D shows the AutoCAD drawing lines of the drawing that was used for reference to create the Revit drawing.  

Can you advise (remind me) how to turn off these CAD reference drawings, or where is the setting to turn these off?

Thanks in advance.
