Working in Revit 2014 & NavisWorks 2014.
The piping insulation which is in the Nav file only shows up periodically. We'll be needing that to identify the best position(s) for the cable/bus tray. I've gone back to the original, unmodified file to try an find a reason. Nothing popped out at me. Does anyone have an idea how to identify the insulation? Maybe even why something would show up inconsistently?
I included a screen shot for a view of the files that are being used.
