Revit A 2009 IFC files in NavisWorks 2009

[balsmark]

Hi,

I have a project model in Revit Architecture 2009 and have exported it to IFC 2x2 and IFC2x3. When I try to open those files in NavisWorks they load to 1% and then nothing happens. I have not experienced this with any other IFC files in Navis?
Revit Structure IFC files reads in fine and is well structured with all relevant infomation brought through as well.
Does anyone have a clue on whats wrong?


Regards,
Björn

I wouldn't recommend using ifc's, you will lose information (physical and data) that is almost guaranteed, this is what people at NavisWorks told me. Exporting an nwc from Revit is the only reliable way.
