Revit 2013 to Navisworks 2013 new selection tree structure

[djc1984]

I am now using the new revit 2013 to navis 2013 export, which has a new selection tree structure within Navis.

This is a nice new feature, but is there any way to not include detail items in the export? (SEE PICTURE BELOW)

I cannot see any reason why we would want the detail items to come through. I cannot switch them off like i do lines with the render style option because they are actually solids.

Also, when exporting revit 2013 to navis 2013, the export option "entire project" needs to be checked, as this is the only way to include rooms in the export. Unfortunately, this option seems to be the reason that we are also getting detail items included in the export.

Any ideas????
