Hi all, I know this has probably seems like Navisworks 101, but I'm looking for a little bit of advice on best practice for creating my NWF file.

Is it best to open my MEP central model in Navisworks and then save this as the NWF file?

I can see the advantage of always having an absolutely latest version of our model visible in the NWF file. Are there any disadvantages of using the Revit file over an exported NWC file?

After this how do you append other companies models, Revit or NWC?

Cheers,
Jon.
