I am working on a large building project with a lot drawings, so I thought I would try to use navisworks cross-referencing to keep all drawings up to date.

My problem is that when exporting the model and dwf-files all elements are supposed to get a GUID-name. Otherwise it is not possible for navisworks to cross-check the drawings.

Does anyone know why not all elements get this GUID-name when exporting from Revit structure 2012?

I'm using the 2012 exporter when exporting to nwc.

It seems that it is wall elements with holes in them and slab elements with holes that do not get GUID-names.
