Hi, How can I fix this problem? This message appears in the .log file generated by revit when trying to export to navis. Other models export ok, this happens only in one model

Have you tried appending the revit model to its own navisworks file to see if you get the same error?

appending the revit model to its own navisworks file ?
Sorry, I dont even understand the concept.
What it consist of?
How can I do it?

@Anonymous No problem! Just open up Navisworks, Click on Append at the top left corner, switch the file type to RVT and find your Revit File. 🙂 Then save as an NWC

I'm having this same problem when i'm trying to export REVIT to NWC.

Do you fixed this problem?

Finally it seamed to be a corrupted family issue.
