I have a rather large assembly to convert to a Revit Family file. All features are successfully recognized as native Revit features. When Inventor finishes publishing, an html-file is displayed, showing the result of the operation. This file shows 169 successes, and one failure, with a very vague error message: 'The object could not be rebuilt due to a Revit error'. Does anyone know of a possible cause for this error? Seeing as the operation takes about half an hour, I'm a little bit hesitant to go 'trial-and-error' on this one.
